CG3 VENTILATOR DESCRIPTIONS

There are 5 different types of CG3 “Classic Gaylord”, water-wash ventilators. The differences involve the type and locationof fire damper and whether the ventilator has a fire damper. Thefirst part of the model number indicates the type of ventilator,see below:

Explanation of Prefixes:CG3 ........... Water-wash ventilator with three-position,

thermostatically activated (electric) damperat air inlet slot.[With Damper motor and 1or more Thermostat(s)]

CG3-FDL ... Water-wash ventilator with three-position, ther-mostatically activated (electric) damper at airinlet slot. A bracket (Fire Damper Lockout)has been added to prevent the damper fromclosing to the fire position.[With Dampermotor and 1 or more Thermostat(s)]

CG3-FDD ... Inlet damper is fixed, and there is a weightedfuse link activated fire damper located at theduct collar. [No Damper motor, No Ther-mostats]

CG3-FDT ... Inlet damper is fixed, and there is a weightedfuse link activated fire damper located at theduct collar, and there is a single thermostatto activate the fire mode in the control cabinetand ventilator. [No Belimo, One Thermo-stat]

CG3-ND Inlet damper is fixed. No Fire Damper at ductcollar. A bracket (Fire Damper Lockout) hasbeen added to show that the damper will notclose to the fire position. [No Dampermotor, No Thermostats]

Summary of CG3 Ventilators:The CG3 and CG3-FDL are very similar. Both have a dampermotor that closes the inlet damper during the wash mode andstays closed until the exhaust fan is started. Both havethermostats that can detect an “Internal Fire”. The maindifference is the CG3-FDL has a Fire Damper Lockout (FDL)bracket added that prevents the inlet damper from closing tothe fire position, so it does NOT have a fire damper.

The CG3-FDD and CG3-FDT are similar to each other. Bothhave fixed inlet dampers and do not have damper motors. Theyboth have fuse link activated fire dampers in the duct collar thatwill close when the temperature reaches 250°F. The CG3-FDThas an added thermostat that will detect an “Internal Fire” andactivate the “Internal Fire Mode”. The CG3-FDD does NOThave any thermostats.

The CG3-ND has a fixed inlet damper and does NOT have afire damper.

GREASE EXTRACTIONThe Gaylord “CG3” Series Ventilator extracts up to 95% of thegrease, dust and lint particles from the airstream passingthrough it, when operated and maintained in accordance withdesign specifications.

The hot, contaminant-laden air rising from the cookingsurface merges with the higher velocity air that wipes the frontof the cooking equipment and extends, like an air blanket, fromthe front edge of the cooking equipment to the air inlet of theventilator. As the air moves through the ventilator at a highspeed, it is forced to make a series of turns around threebaffles. As the high velocity air turns around each baffle, theheavier-than-air particles of grease, dust and lint are thrown outof the airstream by centrifugal force. The extracted grease,dust and lint are collected in the interior of the ventilator,remaining out of the airstream until removed daily by the washcycle.

Baffle #1This baffle, located at the air entrance of the ventilator, is athree position damper. Position 1 is the exhaust on mode asshown in Figure 1 below, position 2 is the wash mode, andposition 3 is the fire mode. When the "Start Fan" button ispushed on the control cabinet, the damper opens to theexhaust mode (position 1) to become the preliminary grease

"CG3" SERIES VENTILATOR PRINCIPLE OF OPERATION

extraction baffle. There is a small sloped grease collectinggutter on the back side of the damper which drains off liquefiedgrease, preventing it from re-entraining into the airstream.

Baffle #2This baffle is located on the interior back wall of the ventilatorand is a stainless steel pipe, equipped with brass spraynozzles on 8" to 10" centers. (Refer to Figure 1) During thewash cycle, hot detergent water is released through thenozzles. If the ventilator’s automatic fire control system isactivated, fire smothering water spray is also released throughthe spray nozzles.

Baffle #3This baffle is located on the back of the inspection doors. Thisbaffle is also a grease collecting gutter, collecting grease, dustand lint extracted by the ventilator - preventing the contaminantsfrom dropping back into the high velocity airstream.

NOTE: Some ventilators may be equipped with optional“Custom Air” baffles (shown dotted) which reduces theexhaust volume where the baffle occurs.

NOTE: Some ventilators may be equipped with optionalcontinuous cold water mist. Refer to Page 24 for details.

WASH CYCLEThe wash cycle is activated each time the exhaust fan is shutoff by pushing the “Start Wash” button on the CommandCenter or as programmed on the clock. When activated theexhaust and supply fans shut off, the damper control isenergized and the damper begins closing forward to the washposition, and once closed the hot water wash sprays come on.The ventilator may be equipped with an optional second washmanifold as shown in Figure 3 and is indicated in the modelnumber, stamped on the ventilator nameplate, by the suffix“DW”. This is typically used when extra heavy duty cookingequipment is under the ventilator.

This hot detergent water washes the day’s grease, dust andlint accumulation from the interior of the ventilator flushing itdown to the main gutter which slopes to a pre-flushed drainwhich leads to the building drain system. Spray nozzles arelocated on 8" to 10" centers on the wash manifold mounted onthe interior back wall of the ventilator. At the end of the washcycle, the water automatically shuts off, and the interior of theventilator is clean - ready for the next day’s operations. Thedamper remains in the wash position until the exhaust fan isrestarted. This is to prevent conditioned air from going up theexhaust system during off hours.

The length of the wash cycle may be set between 3 minutesand 9 minutes. The length of time is dependent upon the typeof cooking equipment being used. Typical settings are 3minutes for light-duty equipment, 5 minutes for medium-dutyequipment, and 9 minutes for heavy-duty equipment. However,adequate cleaning is dependent upon water pressure, watertemperature, daily grease accumulation, the length of thewash cycle, frequency of wash cycle and the type of detergentbeing used. It may be necessary to increase the wash time toachieve proper cleaning. Refer to page 15 for details on settingthe wash time.

INTERNAL FIRE MODE — For CG3 and CG3-FDT only!Automatic internal fire protection is accomplished by theaction of the thermostat(s), which are located at the pointwhere the ductwork joins the ventilator. When the temperatureof the conveying airstream, which must pass over the thermo-stats, reaches 250°F, the system is activated, and thefollowing occurs:

1. The damper begins closing back to the fire position,position 3 as shown in Fig.4—stopping the combustion-supporting, natural draft through the ventilator and creatinga fire barrier to contain the fire in the kitchen. (N/A on CG3-FDT)

2. The exhaust fan serving the ventilator is shut off. Thesupply fan is also shut off.

3. Fire-smothering water spray is released into the interior ofthe ventilator through the spray nozzles.

4. The digital display reads "Fire In Hood, Fan Off, Wash On"for approximately 5 seconds.

5. Then the digital display reads "Fire In Hood, DamperClosing" for approximately 5 seconds.

6. Then the digital display reads "Fire In Hood, Notify FireDepartment". This display stays on until the thermostatcools down below 250°F.


CAUTION:

In case of severe fire the thermostats located in the plenum willactivate. As a precautionary measure, it is recommended thatthe thermostats be replaced.

FIG. 4FIRE CYCLE

7. A red light on the Command Center illuminates.

8. If the Command Center is intertied with a building alarm ormonitoring system, a fire signal would be sent to thatsystem.

9. Upon cooling of the thermostat below 250oF, the CoolDown Cycle starts. The water continues to spray duringthe Cool Down Cycle (2 minutes). The damper moves tothe exhaust position. (N/A on CG3-FDT)

10. While in the cool down cycle the digital display reads"Cool Down Cycle, xxx sec. to end". xxx is the countdownin seconds until the wash turns off. The damper moves tothe exhaust position.

11. At the end of the cool down cycle the wash turns off andthe digital display reads "Fan Off 12:00 (actual time), StartFan>F1". The damper closes to the wash position. (N/Aon CG3-FDT)

NOTE: The water may be shut off prior to the end of the 2 minutecool down cycle by pushing the “Exit” button on the C-6000Command Center. After the water has shut off, the damperremains in the wash position until the “Start Fan” button ispushed.

TESTING INTERNAL FIRE MODE –FOR CG3 AND CG3-FDT ONLY!The internal fire protection system may be tested periodicallyby pushing and holding for 20 seconds, the “Fire TestSwitch” located inside the electrical compartment of thecontrol cabinet. Pushing this switch duplicates thermostaticaction. CAUTION: Before pushing the “Fire Test Switch” ,check to see if the internal fire protection system is tied to thebuilding alarm system.

TO RESUME NORMAL OPERATION

1. To discontinue the 2 minute cool down cycle at any pointduring the cycle, push the “Exit” F5 button on the C-6000Command Center.

2. Push the “Start Fan” F1 button on the Command Center.

SURFACE FIRE PROTECTIONThe National Fire Protection Association, NFPA-96 documentrequires fire extinguishing equipment over all grease producingcooking equipment such as griddles, ranges, fryers, broilers,and woks. In addition, the system must protect the interior ofthe ventilator and the exhaust duct.

The most common fire system is either a wet chemical typeor the Gaylord Quencher water spray system. In the event ofa fire this system would normally be activated and dischargedprior to the ventilator’s internal fire protection. If the fire isunusually severe or the surface fire protection system malfunc-tions, the ventilator’s internal fire protection system wouldactivate, thus providing a second level of defense. Thesesystems may be intertied with the ventilator control cabinet toactivate the External Fire Mode.

FIG. 5BREAK GLASS FIRE SWITCH

C-1357A SERIES

EXTERNAL FIRE MODEAn External Fire Mode is activated by the Ventilator’s FireSuppression (Duct, Plenum, Surface/Appliance) system’smicroswitch or contacts and/or an optional break glass fireswitch (see Figure 5). Terminals 4 & FS are used for theExternal Fire Mode, refer to wiring diagram for details. Thebreak glass fire switch, if used, would normally be located atthe exit of the kitchen. When the External Fire Mode isactivated, the following occurs:

1. The Exhaust Fan comes on immediately if it was off to helpremove smoke, heat, etc.

2. The Supply Fan shuts off immediately.

3. The digital display reads “Ext.FireActive” and alternatesbetween “Reset FireSwitch” and “Fan On, Wash On”.

4. A red light on the Command Center flashes.

5. After a 60-second delay, a fire smothering water spray isreleased into the interior of the ventilator through the spraynozzles. The 60-second delay allows the ventilator’s firesuppression system time to put out the fire, before startingthe water spray.

If the fire intensifies and the thermostat reaches 250°F, the firedamper would then close and the exhaust fan would shut off.See Internal Fire Mode.

To resume normal operations, open the fire switch and flip thetoggle switch to the position marked “normal”. Replace theglass rod and close the cover. Push either the “Start Fan” or“Start Wash” button.

INTERNAL & EXTERNAL FIRE MODES AT THE SAME TIME

It is possible that both the Internal and External Fire modes canbe activated at the same time. If this occurs, the Internal FireMode will override the External Fire mode until the thermostat(s)cool below 250°F. At this point the Cool Down Cycle will startcounting down for 2 minutes. After the Cool Down Cycle, theExternal Fire mode will start.

Special Note: If the control is in the Cool Down Cyclewhen the External Fire mode is activated, the CoolDown Cycle will finish counting down for 2 minutes,before switching to the External Fire Mode.

Starting the Exhaust FanTo start the exhaust fan push the “Start Fan” button on theCommand Center. If the Command Center is programmed tostart the fan automatically, then the start button does not needto be pushed. It is important to start the exhaust fan beforeturning on the cooking equipment.

When the exhaust fan is activated the following occurs:

1. The damper begins opening to the exhaust position.(N/A on CG3-FDD and CG3-ND)

2. A green light on the Command Center illuminates.

3. The supply fan comes on.

4. The digital display reads "Starting Fan & Damper Open-ing" for approximately 5 seconds. Then the digital displayreads "Starting Fan, xx Seconds to Fan On". xx is thecoundown in seconds until the exhaust fan comes on.

5. After the damper fully opens (elapsed time approximately45 seconds) the exhaust fan comes on.

6. The digital display then reads "Fan On 12:00" (currenttime) and "Start Wash> F2".

Stopping the Exhaust Fan andStarting the Wash CycleCAUTION: The cooking equipment must be shut off prior toshutting off the exhaust fan. Failure to do this will causeexcessive heat buildup and could cause the surface fireprotection system to discharge.

To start the wash cycle push the “Start Wash” button on theCommand Center. If the Command Center is programmed tostart the wash automatically, then the start button does notneed to be pushed. When the wash cycle is activated thefollowing occurs:

1. The exhaust and supply fans shut off.

DAILY OPERATION

2. The damper begins closing forward to the wash position.(See Figure 3, page 7). This action takes approximately 45seconds. (N/A on CG3-FDD and CG3-ND)

3. The digital display reads "Starting Wash, Damper Clos-ing" for approximately 5 seconds, then the digital displayreads "Starting Wash, Wash On in xx seconds". xx is thecountdown in seconds to until the wash starts.

4. After the damper closes to the wash position, the hot,detergent injected, water sprays come on to wash awaythe grease collected during the days operation. The washcycle stays on for the length of time programmed in theCommand Center. The length of the wash cycle may beset between 3 minutes and 9 minutes. Typical settings are3 minutes for light-duty equipment, 5 minutes for medium-duty equipment and 9 minutes for heavy-duty equipment.Refer to page 15 for details on setting the wash time.

5. During the wash cycle, the digital display reads "WashOn, Wash #1 xxx seconds". xxx is the coundown inseconds until the wash system shuts off.

6. Upon completion of the wash cycle, the damper stays in theclosed wash position until the exhaust fan is re-started. Thisis to prevent conditioned air from going up the exhaust stackduring off hours.(N/A on CG3-FDD and CG3-ND)

7. The digital display now reads "Fan Off 12:00" (currenttime) and Start Fan>F1.

After the wash cycle is completed, wipe the exposed frontsurface of the damper at the air inlet slot, as well as otherexposed exterior surfaces. (Refer to Figure 7, Page 11).

In very heavy cooking operations it may be necessary to washthe ventilator(s) more than once a day. This can be donemanually by pushing the “Start Wash” button

NOTE: For proper operation of the wash system there mustbe adequate water pressure and temperature. There is apressure/temperature gauge inside the control cabinet.

Water Pressure 40 psi min. - 80 psi max.

Water temperature 140°F min. - 180°F max.

NOTE: Some control cabinets are equipped with a lowdetergent switch. If so equipped, the green light will flash if thedetergent tank is empty or if the detergent pump is malfunc-tioning and detergent is not pumping. The digital display reads"Low Detergent" and the text alternates from "Fill Tank" and"Check Pump". If the detergent tank is filled with water thedetergent switch will activate as if there is no detergent.

NOTE: The ventilator wash system is designed to remove dailyaccumulations of grease within the extractionchamber. If the ventilator is not washed a minimum of onceduring a cooking day, a grease buildup could accumulatewhich the wash system cannot remove. If this occurs, it isrecommended that the ventilator be put through several washcycles by pushing the “Start Wash” button on the CommandCenter. If this does not remove the grease, it will be necessaryto remove the grease manually by using a scraping tool, suchas a putty knife, or retain the services of a commercial hoodcleaning service to steam clean or pressure wash the system.

WARNING: Some commercial hood cleaning services blowa fire retardant chemical into hood and duct systems. Fireretardant chemicals should never be applied to any portion ofThe Gaylord Ventilator. If retardant is applied to the ventilator,it must be removed.

DAILY OPERATIONAll functions of the ventilator, such as starting the exhaust fan,starting the wash cycle, etc., are controlled by the CommandCenter located on the control cabinet. Refer to Pages 14through 17 for detailed instructions on the operation of theCommand Center.

PREVENTIVE MAINTENANCE

PREVENTIVE MAINTENANCEThe following should be checked periodically in order to keepThe Gaylord Ventilator operating at design efficiency:

Weekly1. The detergent tank should be checked at least weekly and

kept full with a recommended detergent. (Refer to Page 13)

Monthly1. The detergent system fittings should be checked at

least monthly. This is an airtight system and fittingsshould be tight. (For complete details refer to the Deter-gent Pump section on Page 12.)

2. At least monthly, at the conclusion of a wash cycle, openthe inspection doors of the ventilator and check to ensurethat the interior has been cleaned of grease, dust, and lint.(Refer to Figure 7) If overall cleaning appears to beinadequate, refer to “Trouble-Shooting of the Wash Sys-tem”, Page 27.

3. The main grease gutter of the ventilator should bechecked at least monthly to remove any foreign materialsuch as paper towels, order chits, etc.

Every Six Months1. Exhaust fan(s) should be checked every six months for

belt tightness, belt alignment, and lubrication of neces-sary moving parts.

NOTE: A blue lithium based grease is best suited for highheat and speed bearing lubrication.

2. Check for proper velocity at air inlet slot. Refer to Pages21 through 23 for method of checking velocity.

3. Test the "Internal Fire Mode" to check for proper damperclosure. Refer to Page 9 for instructions.

4. Detergent tank and foot valve should be cleaned every sixmonths.

INSPECTION AND CLEANING REQUIREMENTSNFPA-96 (Standard for Ventilation Control and Fire Protectionof Commercial Cooking Operations) require that hoods, ductsand exhaust fans be inspected by a properly trained, qualifiedand certified company or person(s) in accordance with thefollowing table.

Upon inspection, if found to be contaminated with depositsfrom grease-laden vapors, the entire exhaust system shall becleaned by a properly trained, qualified, and certified companyor person(s) acceptable to the authority having jurisdiction inaccordance.

DETERGENT PUMP OPERATION

PREVENTIVE MAINTENANCE

As with any piece of fine equipment, a reasonable amount ofcare must be taken to keep it in good working order:

1. Caution should be taken not to spill detergent on theexterior of the pump.

2. A periodic check should be made of all fittingsto guarantee their tightness.

NOTE: The detergent pump motor has sealed bearings andwill not require lubrication.

The Gaylord Ventilator detergent pump is an integral part of thewash-down system of The Gaylord Ventilator. The pump islocated within the control cabinet unless otherwise specified.(Refer to schematics on Pages 33 through 35.)

OPERATIONThe detergent pump is started when the wash cycle begins.The pump draws detergent up from the detergent tank, pushingit through the copper tubing and into the hot water line servingthe ventilator.

NOTE: Some control cabinets are equipped with a lowdetergent switch. If so equipped, the green light will flash if thedetergent tank is empty or if the detergent pump is malfunc-tioning and detergent is not pumping. The digital display reads"Low Detergent" and the text alternates from "Fill Tank" and"Check Pump". If the detergent tank is filled with water thedetergent switch will activate as if there is no detergent.

Initial OperationTo prime and operate the pump for the first time, it is recom-mended that water be used instead of detergent to preventdetergent from spilling in case of leaks at the system’s fittings.

Priming The PumpThe detergent pump is self-priming. Push the pump testswitch, located on the junction box of the motor, and hold downuntil liquid climbs up the vinyl tubing and fills the pump head.The pump will be operating properly when both upper and lowerpoppet checks can be seen moving up and down slightly. If thepump does not self-prime, an air lock may have developedwithin the pump head and the following action should be taken:

1. Hold down pump test switch and loosen top cap slightlyto allow air to be pushed out. Repeat as necessary untilliquid climbs up tube and fills pump head.

Note : Do not overly tighten cap or damage to the pumphead will occur.

2. If the pump still does not work properly, check thefollowing:

A. Foot valve should be clean and immersed in the liquid.

B. Check all fittings to ensure an airtight system.

C. Poppet checks within the foot valve, pump head and brass check valve should be clean and operating freely.

D. Detergent lines should be free and clear.

DETERGENT FLOWDetergent flow is initially factory set according to the pipe size of thecontrol cabinet (refer to chart). Generally, the factory setting will besufficient to provide adequate cleaning of the ventilator. However,adequate cleaning is dependent upon a number of factors:

1. Temperature of hot water 4. Wash cycle time2. Water pressure 5. Frequency of wash cycle3. Daily grease accumulation 6. Type of detergent

Depending upon these factors, it may be necessary to adjustthe detergent flow. Adjustment may be accomplished bychanging the cam to a different size. To change the cam:

1. Loosen Allen set screw on brass cam.2. Remove cam and replace with next size as required.3. Cam #1 minimum setting. Cam #4 maximum setting.

NOTE: Cams are available from Gaylord Industries or yourGaylord Certified Service Agency.

FORMULA G-510 is the only cleaner recommended by Gay-lord Industries for use in the washdown system of The GaylordVentilator. FORMULA G-510 is a concentrated colloid cleanerspecially formulated to remove the daily accumulation ofgrease inside The Gaylord Ventilator without damaging therubber and synthetic parts of the detergent pumping system.FORMULA G-510 is biodegradable, safe for kitchen person-nel, and has a variety of uses.

DILUTION OF FORMULA G-510 FORVENTILATOR CLEANINGNormal CleaningFor ventilators covering cooking equipment such as broilers,griddles, fryers, or any other heavy grease producing equip-ment, fill the detergent tank with full strength FORMULAG-510.

Light-Duty CleaningFor ventilators covering light grease producing equipment suchas ovens, kettles, steamers and ranges, fill the detergent tankwith a mixture of one part FORMULA G-510 to one part water.

Cleaning the Ventilator ExteriorMix one part FORMULA G-510 to twenty parts water in handspray bottle. Spray on and wipe off. NOTE: Once a day, thissame solution should be used to clean the front of the firedamper and main grease extracting baffle.

FOR OTHER CLEANING JOBSThe colloidal action of FORMULA G-510 makes it a cleanerespecially well-suited for use in kitchens. The colloids breakup dirt and grease into millions of tiny particles that constantlyrepel each other. These particles cannot recombine or rede-posit on a surface and are, therefore, easily washed away.FORMULA G-510 is biodegradable and contains no harshchemicals, yet offers outstanding performance on the tough-est cleaning jobs.

Use a mixture of one part FORMULA G-510 to twenty partswater for:

VINYL/PLASTIC/WALLS...Removes dirt, grease, food de-posits and fingerprints.REFRIGERATORS...Removes dirt, spilled milk, blood,mildew and objectionable odors.RESTROOMS...Add a disinfectant to clean all fixtures,walls, floors, etc.

Use a mixture of one part FORMULA G-510 to five parts waterfor extremely heavy grease build-up, such as on the floor andon equipment around deep-fryers. Spray on and rinse or wipeoff. For extremely soiled areas, gentle agitation, followed by asoaking period, will result in more thorough cleaning.

MODEL C-6000 SERIES COMMAND CENTER - INSTRUCTIONS

General Description:The C-6000 Command Center is designed to start and stop theexhaust fan and wash up to 5 groups of ventilators in sequencewith a delay period between each group. A sequence wash maybe necessary if the building’s hot water system is not capableof supplying the required volume of water at one given time.

The exhaust fan and wash sequence may be started Manu-ally by pushing the “Start Fan ” or “Start Wash ” buttons, ormay be programmed for Automatic operation.

Programmed operations may include:1. Starting the exhaust fan once within a 24-hour period.

2. Stopping the exhaust fan and starting the wash cyclesequence once within a 24-hour period

The C-6000 Command Center provides information and pro-gramming for various functions by accessing nine different menucatagories. An overview of the nine menu items are as follows:

1. Service - Displays Gaylord's website address:gaylordusa.com

2. Detergent - Displays Toll-Free Number to order deter-gent: 800-286-2010

3. Wash Length - Sets length of each wash cycle from 3 to9 minutes

4. Delay Time (for sequence wash units only) - Sets delaybetween washes from 1 minute to 99 minutes

5. Set Clock - Day, hour and minutes

6. AutoMode [M or A] - Sets the C-6000 to Manual orAutomatic modes. In Automatic mode, the C-6000 willstart the Fan and Wash at the preset times that were setusing the Set Wash Times option.

A = Automatic / M = Manual

Also allows individual days (Mon, Tues., etc.) to be set ONor OFF when Automatic mode is selected.

7. Set Wash Times - Sets Start Times for Automatic startof Fan and wash when C-6000 is set to Automatic mode.

4. Skipping a day so the exhaust fan and wash cycle do notoperate for holidays or specific days within a 7-day weekwhen the kitchen is not operating.

OPERATING INSTRUCTIONS

1. Push "Start Fan" before turning on cooking equipment.Note: There is a 45 second delay after pushing the buttonbefore the fan starts to allow the damper to open to the"Exhaust" position.

2. At the end of the day, or whenever cooking is completed,push "Start Wash". This will turn off the exhaust fan andclose the damper forward to the "Wash" position.

Note: There is a 45 second delay after pushing the buttonbefore the wash cycle starts, to allow the damper, if soequipped, to close to the "Wash" position. After closing, thetimed wash cycle begins. Damper stays closed until "StartFan" is pushed. Note: 24 hour kitchens must push "Start Wash"at least once a day, or as needed for proper cleaning.3. To set the length of the time for the wash cycle, press

"Menu", then press [F1] until "Wash Length" appears on thedisplay. Follow the instructions on the display to edit thelength of washes as necessary.

Each Gaylord Ventilator is engineered to properly ventilatethe specific cooking operation. The exhaust air volume is en-gineered as a specific volume per lineal ft. of ventilator and isdetermined by the type of cooking equipment being ventilated.The following Air Volume Chart lists the various volumes perlineal ft. designs.

A ventilator may be designed to operate at two different airvolumes. For example, half the ventilator may operate at 150CFM/Lin. Ft. by utilizing “Custom Air” Baffles, and the otherhalf at 250 CFM/Lin. Ft.

Refer to “Measuring Inlet Slot Velocity” on Page 21 for instruc-tions on how to determine the designed Air Volume/Lin. Ft.

The total exhaust volume for each ventilator is stamped on theventilator nameplate. (Refer to Figure 13 on Page 23.)

DUCT VELOCITYBased between 1700 FPM - 1900 FPM

WATER TEMPERATURE REQUIREMENTS140°F Min. - 180°F Max.

HOT WATER PRESSURE REQUIREMENTS40 PSI Min. - 80 PSI Max.HOT WATER CONSUMPTIONSingle Wash - .60 GPM/Lineal Ft. @ 40 PSI Average

.90 GPM/Lineal Ft. @ 80 PSI Average

Dual Wash - 1.14 GPM/Lineal Ft. @ 40 PSI Average1.67 GPM/Lineal Ft. @ 80 PSI Average

The length of the wash cycle may be set between 3 minutesand 9 minutes. The length of time is dependent upon the typeof cooking equipment being used. Typical settings are 3minutes for light-duty equipment, 5 minutes for medium-dutyequipment, and 9 minutes for heavy-duty equipment. However,adequate cleaning is dependent upon water pressure, watertemperature, daily grease accumulation, the length of thewash cycle, frequency of wash cycle and the type of detergentbeing used. It may be necessary to increase the wash time toachieve proper cleaning. Refer to page 15 for details on settingthe wash time.

RP DEVICE - INITIAL START UP

RP DEVICEThe reduced pressure principle device (RP) is required toprevent contaminated water from backflowing upstream topotable water. The unit provided in the Gaylord control cabinetis manufactured by Watts Regulator Co.

1. Initial Start-up - To avoid water hammer or shock damageperform the following initial start-up procedures:

A. Close the outlet hand valve.

B. Open the inlet hand valve slowly, fill the valve and bleed

the air through test cock number 2, 3, and 4.

C. When the valve is filled, open the outlet hand valveslowly and fill the remaining supply system. The initialstart-up procedure is now complete.

The reduced pressure principle device type backflow preventer(Refer to Figure 11A &11B) consists of two primary chamberswith spring loaded check valves and a secondary chamber witha spring loaded relief valve. This device prevents backflow byopening and closing the check valves if the pressure from theinlet side to the outlet side of the device varies.

1. Intermittent Discharge - Intermittent discharge of waterthrough the relief valve is fairly common and usually occursif there is inlet pressure fluctuations of more than 3 psi andwhen the solenoid valve closes after a wash cycle.

2. Continuous Discharge - If there is continuous dischargeof water out the relief valve when the ventilator is not in awash cycle, do the following:

A. Leave the inlet hand valve open and close the outlethand valve. If there is still continuous discharge itindicates that foreign material is preventing the firstcheck valve from closing. If flushing will not clear theunit, remove and clean the first check valve.

B. If there is continuous discharge of water out of therelief valve during a wash cycle, there is foreignmaterial preventing complete closing of the reliefvalve. Flushing the relief valve may correct this condition.

Repeat procedure if necessary. If flushing does not stopdischarge with flow through the device, remove and clean reliefvalve.

In no case should the relief valve outlet port be plugged, closedoff or restricted.

This device should be inspected occasionally for continualdischarge from the relief valve, which indicates a need formaintenance. It is recommended that the RP device beinspected and tested once a year.

NOTE: Some regulations require annual inspection and test-ing by a company certified to perform such duties.

See Instruction Manual IS-TK-DP, obtainable from your Wattsinstaller or distributor. For the name of your nearest installer ordistributor, call Watts Regulator at (978) 688-1811.

MEASURING INLET SLOT VELOCITY

Smoke capture and grease extraction efficiency are depen-dent upon the proper air velocity at the inlet slot of the ventilator.

The “Air Velocity Chart” below gives the optimum inlet slotvelocity and the minimum and maximum allowed velocities. Ifthe slot velocity is below or above the minimum or maximum,the exhaust fan must be adjusted accordingly.

NOTE: The height of the inlet slot can vary depending upon thedesign of the ventilator. It is, therefore, important to firstmeasure the inlet slot and compare it to the chart below todetermine the required average inlet slot velocity. The de-signed air volume per lineal foot is related to the velocity asshown on the chart below. The total air volume for the ventilatorcan be found on the ventilator nameplate. (Refer to Figure 13).

Air velocity readings less than what is specified on the “AirVelocity Chart” may allow smoke and grease to escape theconfines of the ventilator and/or reduce grease extractionefficiency. This can result in grease deposits which lead tosanitation problems or fire hazards if left uncorrected. If the airvelocity readings are higher than the maximum allowed, it willrequire more energy to operate the exhaust fan, excessivenoise levels will result, and grease can be pulled through theextractor depositing in the duct and fan.

Higher or lower velocities than the allowed will normally put theentire heating and ventilating system out of balance.

*The nominal height of the front inlet slot on “DS” series ventilators is always 3".

CROSS SECTION OF TYPICALVENTILATOR INLET SLOTS

The standard instrument used for measuring the inlet velocitieson a Gaylord Ventilator is a Pacer, Model DA40 or DA4000Digital Anemometer. This instrument is the easiest, mostaccurate and the best suited for measuring ventilator inlet slotvelocities. To take accurate air velocity readings, follow theinstructions at right.

Instructions1. It is first necessary to determine if the ventilator includesCustom Air baffles as shown in fig. 12B. If shop drawings areavailable, and if equipped, the custom baffles and their locationwill be noted on the front elevation. If not available, to determineif Custom Air baffles are provided, open the inspection doorand look for the top custom air baffle, as shown in Fig. 12B.

2. If the ventilator includes Custom Air baffles, it will benecessary to take two sets of readings - one for the section ofventilator that includes Custom Air baffles and one where itdoes not.

3. Attached the sensing head guide bracket, Gaylord PartNumber 18408, to the sensing head.

4. Attach the cable from the sensing head to the meter and thehandle sections to the sensing head.

5. Place the sensing head guide bracket against the lower lipof the inlet slot as illustrated.

6. Using the 16 second averaging feature on the meter, slidethe sensing head along the slot, back and forth, for a 3'-0" to4'-0" distance, and record the velocity at the end of the 16second mark. Continue this process for the full length of theventilator.

Imortant Note: If the ventilator includes custom air baffles asillustrated in Fig. 12B, always take separate readings on thesection of the ventilator that includes custom air from thesection that does not have the baffles. Non custom air andcustom air readings must be recorded seperately. Do notaverage them together.

Important Note: On the rear slot of a Model BDL-DS Series,do not use the guide bracket. Refer to Figure 12C.

7. Record the velocity (fpm) on the start up inspection reportform. A sample report form, which can be photocopied, isprovided on page 52.

8. The designed, or optimum velocity, is noted on the shopdrawings and the Air Velocity Chart on page 21. Two velocitieswill be noted if the ventilator includes custom air baffles.

9. Compare the recorded air velocity to the designed airvelocity shown on the shop drawings or the Air Velocity Charton page 21. The recorded velocity may be slightly lower or

higher providing that it is within the minimum and maxi-mum range as shown on the Air Velocity Chart .

If the air velocity is outside the minimum/maximum range, the performanceof the ventilator will be affected andtherefore the exhaust fan must beadjusted.

FIG. 14CONTINUOUS COLD WATER MIST

OPTIONAL CONTINUOUS COLD WATER MIST

GENERAL

Continuous cold water mist is an option on all “CG3” Seriesventilators and is typically used on ventilators that cover solidfuel burning appliances such as mesquite broilers.Continuous cold water mist ventilators incorporate a watermanifold with spray nozzles, located at the lower edge of theair inlet slot. (Refer to Figure 14) When the exhaust fan isstarted, the solenoid valve in the cold water loop in the Gaylordcontrol cabinet opens (refer to illustration on Page 36), turningon the mist nozzles which remain on as long as the exhaust fanis on. The nozzles produce a very find mist and are located sothat the entire air stream passes through the mist. The purposeof the mist is to knock down any hot embers, produced by thesolid fuel, that may be drawn up into the ventilator and to cooldown the exhaust air.

ENGINEERING1. Pipe Size - 1/2" cold water supply required to the control

cabinet.

2. Water Pressure - 40 psi flow pressure. The control cabinetis equipped with an adjustable pressure regulator.

3. Water Consumption - .66 gph/lineal ft. of ventilator.

MAINTENANCEEvery six months check the following:

1. Water Pressure - Turn on the exhaust fan, opening thecontrol cabinet door and check the water pressure gaugein the cold water loop. Water flow pressure should be at 40psi. If it is not, adjust the pressure regulator until 40 psi isachieved.

2. Mist Nozzles - Turn on the exhaust fan, look into the airinlet slot and check each mist nozzle for proper spray.Remove and clean the nozzle if necessary.

TROUBLE-SHOOTING1. If the mist nozzles do not come on when the fan is started,

check the following:

A. Open the electrical compartment of the control cabinetand check to ensure that the cold water mist overrideswitch is in the “On” position.

B. Check the cold water mist hand valve in the controlcabinet to ensure that it is in the “Open” position.

C. Check the cold water mist solenoid coil for voltage.Also check the coil for continuity.

D. Foreign material in the cold water supply line may haveclogged the solenoid valve and prevented its opening.If this is the case, a alight tap on the solenoid valvehousing should release the valve.

2. If water mist is spraying out of the air inlet slot, check thefollowing:

A. With the cold water mist on, open the control cabinetand check the pressure gauge to ensure that the flowpressure is not above 40 psi. Adjust the pressurereducing valve if necessary.

B. With the cold water mist on, check the mist nozzlesfor even spray. Foreign particles in the nozzle couldcause an erratic mist causing it to come out the airinlet slot.

STANDARD VENTILATOR MODELS

STANDARD MAKE-UP AIR OPTIONSThe make-up air options shown below are available on all BDL Series Ventilators.

Except the MAI Series is not available on the CG3-BDL-CL.

This method of introducing air into the hood istypically referred to as the “short circuit” method.This design has very limited applications and theamount of supply air able to be introduced variesconsiderably with the type of cooking equip-ment. This air may be untempered air in mostareas depending upon climatic conditions andthe type of cooking equipment. The differencebetween the quantity of air being introduced andthe amount of air being exhausted must be sup-plied through a traditional make-up air system.

This method of introducing make-up air into thekitchen is flexible and has many advantages.Make-up air is discharged through stainless steelperforated panels as illustrated (MAW Series) oroptional registers. Typical supply volume is 80%of the exhaust or more, depending on air bal-ance desired. Supply air temperatures shouldrange from 60 to 65°F (16 to 18°C), but may beas low as 50°F (10°C) depending on air volume,distribution, and internal heat load.
