CG3 VENTILATOR DESCRIPTIONS
There are 5 different types of CG3 “Classic Gaylord”, waterwash ventilators. The differences involve the type and location
of fire damper and whether the ventilator has a fire damper. The
first part of the model number indicates the type of ventilator,
see below:
Explanation of Prefixes:

Summary of CG3 Ventilators:
The CG3 and CG3-FDL are very similar. Both have a damper
motor that closes the inlet damper during the wash mode and
stays closed until the exhaust fan is started. Both have
thermostats that can detect an “Internal Fire”. The main
difference is the CG3-FDL has a Fire Damper Lockout (FDL)
bracket added that prevents the inlet damper from closing to
the fire position, so it does NOT have a fire damper.
The CG3-FDD and CG3-FDT are similar to each other. Both
have fixed inlet dampers and do not have damper motors. They
both have fuse link activated fire dampers in the duct collar that
will close when the temperature reaches 250°F. The CG3-FDT
has an added thermostat that will detect an “Internal Fire” and
activate the “Internal Fire Mode”. The CG3-FDD does NOT
have any thermostats.
The CG3-ND has a fixed inlet damper and does NOT have a
fire damper.

"CG3" SERIES VENTILATOR PRINCIPLE OF OPERATION
GREASE EXTRACTION
The Gaylord “CG3” Series Ventilator extracts up to 95% of the
grease, dust and lint particles from the airstream passing
through it, when operated and maintained in accordance with
design specifications.
The hot, contaminant-laden air rising from the cooking
surface merges with the higher velocity air that wipes the front
of the cooking equipment and extends, like an air blanket, from
the front edge of the cooking equipment to the air inlet of the
ventilator. As the air moves through the ventilator at a high
speed, it is forced to make a series of turns around three
baffles. As the high velocity air turns around each baffle, the
heavier-than-air particles of grease, dust and lint are thrown out
of 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 wash
cycle.
Baffle #1
This baffle, located at the air entrance of the ventilator, is a
three position damper. Position 1 is the exhaust on mode as
shown in Figure 1 below, position 2 is the wash mode, and
position 3 is the fire mode. When the "Start Fan" button is
pushed on the control cabinet, the damper opens to the
exhaust mode (position 1) to become the preliminary grease
extraction baffle. There is a small sloped grease collecting
gutter on the back side of the damper which drains off liquefied
grease, preventing it from re-entraining into the airstream.
Baffle #2
This baffle is located on the interior back wall of the ventilator
and is a stainless steel pipe, equipped with brass spray
nozzles on 8" to 10" centers. (Refer to Figure 1) During the
wash cycle, hot detergent water is released through the
nozzles. If the ventilator’s automatic fire control system is
activated, fire smothering water spray is also released through
the spray nozzles.
Baffle #3
This baffle is located on the back of the inspection doors. This
baffle is also a grease collecting gutter, collecting grease, dust
and lint extracted by the ventilator - preventing the contaminants
from dropping back into the high velocity airstream.
NOTE: Some ventilators may be equipped with optional
“Custom Air” baffles (shown dotted) which reduces the
exhaust volume where the baffle occurs.
NOTE: Some ventilators may be equipped with optional
continuous cold water mist. Refer to Page 24 for details.

"CG3" SERIES VENTILATOR PRINCIPLE OF OPERATION
WASH CYCLE
The wash cycle is activated each time the exhaust fan is shut
off by pushing the “Start Wash” button on the Command
Center or as programmed on the clock. When activated the
exhaust and supply fans shut off, the damper control is
energized and the damper begins closing forward to the wash
position, and once closed the hot water wash sprays come on.
The ventilator may be equipped with an optional second wash
manifold as shown in Figure 3 and is indicated in the model
number, stamped on the ventilator nameplate, by the suffix
“DW”. This is typically used when extra heavy duty cooking
equipment is under the ventilator.
This hot detergent water washes the day’s grease, dust and
lint accumulation from the interior of the ventilator flushing it
down to the main gutter which slopes to a pre-flushed drain
which leads to the building drain system. Spray nozzles are
located on 8" to 10" centers on the wash manifold mounted on
the interior back wall of the ventilator. At the end of the wash
cycle, the water automatically shuts off, and the interior of the
ventilator is clean - ready for the next day’s operations. The
damper remains in the wash position until the exhaust fan is
restarted. This is to prevent conditioned air from going up the
exhaust system during off hours.
The length of the wash cycle may be set between 3 minutes
and 9 minutes. The length of time is dependent upon the type
of cooking equipment being used. Typical settings are 3
minutes for light-duty equipment, 5 minutes for medium-duty
equipment, and 9 minutes for heavy-duty equipment. However,
adequate cleaning is dependent upon water pressure, water
temperature, daily grease accumulation, the length of the
wash cycle, frequency of wash cycle and the type of detergent
being used. It may be necessary to increase the wash time to
achieve proper cleaning. Refer to page 15 for details on setting
the wash time.

"CG3" SERIES VENTILATOR PRINCIPLE OF OPERATION
INTERNAL FIRE MODE — For CG3 and CG3-FDT only!
Automatic internal fire protection is accomplished by the
action of the thermostat(s), which are located at the point
where the ductwork joins the ventilator. When the temperature
of the conveying airstream, which must pass over the thermostats, reaches 250°F, the system is activated, and the
following occurs:
1. The damper begins closing back to the fire position,
position 3 as shown in Fig.4—stopping the combustionsupporting, natural draft through the ventilator and creating
a fire barrier to contain the fire in the kitchen. (N/A on CG3FDT)
2. The exhaust fan serving the ventilator is shut off. The
supply fan is also shut off.
3. Fire-smothering water spray is released into the interior of
the 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, Damper
Closing" for approximately 5 seconds.
6. Then the digital display reads "Fire In Hood, Notify Fire
Department". This display stays on until the thermostat
cools down below 250°F.
7. A red light on the Command Center illuminates.
8. If the Command Center is intertied with a building alarm or
monitoring system, a fire signal would be sent to that
system.
9. Upon cooling of the thermostat below 250
Down Cycle starts. The water continues to spray during
the Cool Down Cycle (2 minutes). The damper moves to
the 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 countdown
in seconds until the wash turns off. The damper moves to
the exhaust position.
11. At the end of the cool down cycle the wash turns off and
the digital display reads "Fan Off 12:00 (actual time), Start
Fan>F1". The damper closes to the wash position. (N/A
on CG3-FDT)

NOTE: The water may be shut off prior to the end of the 2 minute
cool down cycle by pushing the “Exit” button on the C-6000
Command Center. After the water has shut off, the damper
remains in the wash position until the “Start Fan” button is
pushed.
CAUTION:
In case of severe fire the thermostats located in the plenum will
activate. As a precautionary measure, it is recommended that
the thermostats be replaced.

EXTERNAL FIRE MODE
An External Fire Mode is activated by the Ventilator’s Fire
Suppression (Duct, Plenum, Surface/Appliance) system’s
microswitch or contacts and/or an optional break glass fire
switch (see Figure 5). Terminals 4 & FS are used for the
External Fire Mode, refer to wiring diagram for details. The
break glass fire switch, if used, would normally be located at
the exit of the kitchen. When the External Fire Mode is
activated, the following occurs:
1. The Exhaust Fan comes on immediately if it was off to help
remove smoke, heat, etc.
2. The Supply Fan shuts off immediately.
3. The digital display reads “Ext.FireActive” and alternates
between “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 is
released into the interior of the ventilator through the spray
nozzles. The 60-second delay allows the ventilator’s fire
suppression system time to put out the fire, before starting
the water spray.
If the fire intensifies and the thermostat reaches 250°F, the fire
damper would then close and the exhaust fan would shut off.
See Internal Fire Mode.
To resume normal operations, open the fire switch and flip the
toggle switch to the position marked “normal”. Replace the
glass rod and close the cover. Push either the “Start Fan” or
“Start Wash” button.
TESTING INTERNAL FIRE MODE –
FOR CG3 AND CG3-FDT ONLY!
The internal fire protection system may be tested periodically
by pushing and holding for 20 seconds, the “Fire Test
Switch” located inside the electrical compartment of the
control cabinet. Pushing this switch duplicates thermostatic
action.
CAUTION: Before pushing the “Fire Test Switch”,
check to see if the internal fire protection system is tied to the
building alarm system.
TO RESUME NORMAL OPERATION
1. To discontinue the 2 minute cool down cycle at any point
during the cycle, push the “Exit” F5 button on the C-6000
Command Center.
2. Push the “Start Fan” F1 button on the Command Center.
SURFACE FIRE PROTECTION
The National Fire Protection Association, NFPA-96 document
requires fire extinguishing equipment over all grease producing
cooking equipment such as griddles, ranges, fryers, broilers,
and woks. In addition, the system must protect the interior of
the ventilator and the exhaust duct.
The most common fire system is either a wet chemical type
or the Gaylord Quencher water spray system. In the event of
a fire this system would normally be activated and discharged
prior to the ventilator’s internal fire protection. If the fire is
unusually severe or the surface fire protection system malfunctions, the ventilator’s internal fire protection system would
activate, thus providing a second level of defense. These
systems may be intertied with the ventilator control cabinet to
activate the External Fire Mode.

INTERNAL & EXTERNAL FIRE MODES AT THE SAME TIME
It is possible that both the Internal and External Fire modes can
be activated at the same time. If this occurs, the Internal Fire
Mode will override the External Fire mode until the thermostat(s)
cool below 250°F. At this point the Cool Down Cycle will start
counting down for 2 minutes. After the Cool Down Cycle, the
External Fire mode will start.
Special Note: If the control is in the Cool Down Cycle
when the External Fire mode is activated, the Cool
Down Cycle will finish counting down for 2 minutes,
before switching to the External Fire Mode.
Summary of Both Fire Modes at the Same Time

Starting the Exhaust Fan
To start the exhaust fan push the “Start Fan” button on the
Command Center. If the Command Center is programmed to
start the fan automatically, then the start button does not need
to be pushed. It is important to start the exhaust fan before
turning 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 display
reads "Starting Fan, xx Seconds to Fan On". xx is the
coundown in seconds until the exhaust fan comes on.
5. After the damper fully opens (elapsed time approximately
45 seconds) the exhaust fan comes on.
6. The digital display then reads "Fan On 12:00" (current
time) and "Start Wash> F2".
Stopping the Exhaust Fan and
Starting the Wash Cycle
CAUTION: The cooking equipment must be shut off prior to
shutting off the exhaust fan. Failure to do this will cause
excessive heat buildup and could cause the surface fire
protection system to discharge.
To start the wash cycle push the “Start Wash” button on the
Command Center. If the Command Center is programmed to
start the wash automatically, then the start button does not
need to be pushed. When the wash cycle is activated the
following occurs:
1. The exhaust and supply fans shut off.
2. The damper begins closing forward to the wash position.
(See Figure 3, page 7). This action takes approximately 45
seconds. (N/A on CG3-FDD and CG3-ND)
3. The digital display reads "Starting Wash, Damper Closing" for approximately 5 seconds, then the digital display
reads "Starting Wash, Wash On in xx seconds". xx is the
countdown 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 away
the grease collected during the days operation. The wash
cycle stays on for the length of time programmed in the
Command Center. The length of the wash cycle may be
set between 3 minutes and 9 minutes. Typical settings are
3 minutes for light-duty equipment, 5 minutes for mediumduty 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 "Wash
On, Wash #1 xxx seconds". xxx is the coundown in
seconds until the wash system shuts off.
6. Upon completion of the wash cycle, the damper stays in the
closed wash position until the exhaust fan is re-started. This
is to prevent conditioned air from going up the exhaust stack
during off hours.(N/A on CG3-FDD and CG3-ND)
7. The digital display now reads "Fan Off 12:00" (current
time) and Start Fan>F1.
After the wash cycle is completed, wipe the exposed front
surface of the damper at the air inlet slot, as well as other
exposed exterior surfaces. (Refer to Figure 7, Page 11).
In very heavy cooking operations it may be necessary to wash
the ventilator(s) more than once a day. This can be done
manually by pushing the “Start Wash” button
NOTE: For proper operation of the wash system there must
be adequate water pressure and temperature. There is a
pressure/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 low
detergent switch. If so equipped, the green light will flash if the
detergent tank is empty or if the detergent pump is malfunctioning 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 the
detergent switch will activate as if there is no detergent.
NOTE: The ventilator wash system is designed to remove
accumulations of grease within the extraction
chamber. If the ventilator is not washed a minimum of once
during a cooking day, a grease buildup could accumulate
which the wash system cannot remove. If this occurs, it is
recommended that the ventilator be put through several wash
cycles by pushing the “Start Wash” button on the Command
Center. If this does not remove the grease, it will be necessary
to remove the grease manually by using a scraping tool, such
as a putty knife, or retain the services of a commercial hood
cleaning service to steam clean or pressure wash the system.
daily
WARNING: Some commercial hood cleaning services blow
a fire retardant chemical into hood and duct systems. Fire
retardant chemicals should never be applied to any portion of
The Gaylord Ventilator. If retardant is applied to the ventilator,
it must be removed.

PREVENTIVE MAINTENANCE
PREVENTIVE MAINTENANCE
The following should be checked periodically in order to keep
The Gaylord Ventilator operating at design efficiency:
Weekly
1. The detergent tank should be checked at least weekly and
kept full with a recommended detergent. (Refer to Page 13)
Monthly
1. The detergent system fittings should be checked at
least monthly. This is an airtight system and fittings
should be tight. (For complete details refer to the Detergent Pump section on Page 12.)
2. At least monthly, at the conclusion of a wash cycle, open
the inspection doors of the ventilator and check to ensure
that the interior has been cleaned of grease, dust, and lint.
(Refer to Figure 7) If overall cleaning appears to be
inadequate, refer to “Trouble-Shooting of the Wash Sys-
tem”, Page 27.
3. The main grease gutter of the ventilator should be
checked at least monthly to remove any foreign material
such as paper towels, order chits, etc.
Every Six Months
1. 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 high
heat and speed bearing lubrication.
2. Check for proper velocity at air inlet slot. Refer to Pages
21 through 23 for method of checking velocity.
3. Test the "Internal Fire Mode" to check for proper damper
closure. Refer to Page 9 for instructions.
4. Detergent tank and foot valve should be cleaned every six
months.
INSPECTION AND CLEANING REQUIREMENTS
NFPA-96 (Standard for Ventilation Control and Fire Protection
of Commercial Cooking Operations) require that hoods, ducts
and exhaust fans be inspected by a properly trained, qualified
and certified company or person(s) in accordance with the
following table.
Upon inspection, if found to be contaminated with deposits
from grease-laden vapors, the entire exhaust system shall be
cleaned by a properly trained, qualified, and certified company
or person(s) acceptable to the authority having jurisdiction in
accordance.
When a vent cleaning service is used, a certificate showing
date of inspection or cleaning shall be maintained on the
premises. After cleaning is completed, the vent cleaning
contractor shall place or display within the kitchen area a label
indicating the date cleaned and the name of the servicing
company. It shall also indicate areas not cleaned.

DETERGENT PUMP OPERATION
The Gaylord Ventilator detergent pump is an integral part of the
wash-down system of The Gaylord Ventilator. The pump is
located within the control cabinet unless otherwise specified.
(Refer to schematics on Pages 33 through 35.)
OPERATION
The detergent pump is started when the wash cycle begins.
The pump draws detergent up from the detergent tank, pushing
it through the copper tubing and into the hot water line serving
the ventilator.
NOTE: Some control cabinets are equipped with a low
detergent switch. If so equipped, the green light will flash if the
detergent tank is empty or if the detergent pump is malfunctioning 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 the
detergent switch will activate as if there is no detergent.
Initial Operation
To prime and operate the pump for the first time, it is recom-
mended that water be used instead of detergent to prevent
detergent from spilling in case of leaks at the system’s fittings.
Priming The Pump
The detergent pump is self-priming. Push the pump test
switch, located on the junction box of the motor, and hold down
until liquid climbs up the vinyl tubing and fills the pump head.
The pump will be operating properly when both upper and lower
poppet checks can be seen moving up and down slightly. If the
pump does not self-prime, an air lock may have developed
within the pump head and the following action should be taken:
1. Hold down pump test switch and loosen top cap slightly
to allow air to be pushed out. Repeat as necessary until
liquid climbs up tube and fills pump head.
Note: Do not overly tighten cap or damage to the pump
head will occur.
2. If the pump still does not work properly, check the
following:
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.
PREVENTIVE MAINTENANCE
As with any piece of fine equipment, a reasonable amount of
care must be taken to keep it in good working order:
1. Caution should be taken not to spill detergent on the
exterior of the pump.
2. A periodic check should be made of all fittings
to guarantee their tightness.
NOTE: The detergent pump motor has sealed bearings and
will not require lubrication.

control cabinet (refer to chart). Generally, the factory setting will be
sufficient 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 time
2. Water pressure 5. Frequency of wash cycle
3. Daily grease accumulation 6. Type of detergent
Depending upon these factors, it may be necessary to adjust
the detergent flow. Adjustment may be accomplished by
changing 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 your
Gaylord Certified Service Agency.

DETERGENT FOR THE WASH SYSTEM
FORMULA G-510 is the only cleaner recommended by Gaylord Industries for use in the washdown system of The Gaylord
Ventilator. FORMULA G-510 is a concentrated colloid cleaner
specially formulated to remove the daily accumulation of
grease inside The Gaylord Ventilator without damaging the
rubber and synthetic parts of the detergent pumping system.
FORMULA G-510 is biodegradable, safe for kitchen personnel, and has a variety of uses.
DILUTION OF FORMULA G-510 FOR
VENTILATOR CLEANING
Normal Cleaning
For ventilators covering cooking equipment such as broilers,
griddles, fryers, or any other heavy grease producing equipment, fill the detergent tank with full strength FORMULA
G-510.
Light-Duty Cleaning
For ventilators covering light grease producing equipment such
as ovens, kettles, steamers and ranges, fill the detergent tank
with a mixture of one part FORMULA G-510 to one part water.
Cleaning the Ventilator Exterior
Mix one part FORMULA G-510 to twenty parts water in hand
spray bottle. Spray on and wipe off. NOTE: Once a day, this
same solution should be used to clean the front of the fire
damper and main grease extracting baffle.
FOR OTHER CLEANING JOBS
The colloidal action of FORMULA G-510 makes it a cleaner
especially well-suited for use in kitchens. The colloids break
up dirt and grease into millions of tiny particles that constantly
repel 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 harsh
chemicals, yet offers outstanding performance on the tough-
est cleaning jobs.
Use a mixture of one part FORMULA G-510 to twenty parts
water 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 water
for extremely heavy grease build-up, such as on the floor and
on equipment around deep-fryers. Spray on and rinse or wipe
off. For extremely soiled areas, gentle agitation, followed by a
soaking period, will result in more thorough cleaning.
DON’T be afraid to experiment with FORMULA G-510 because
it contains no phosphates, nitrates, enzymes, sulfates, sulfonates or silicates.
LIMITED WARRANTY
G-510 CHEMICAL DIVISION warrants that FORMULA G-510 will not cause cleansing agent damage
to the rubber and synthetic parts of the injection pump

CHEMICAL DIVISION’S obligation under this warranty and any warranties implied by law shall be
limited to repairing or replacing, at its option, any of

examination shall disclose to its satisfaction to have
been damaged by the use of FORMULA G-510 for the
life of the detergent pumping system. This warranty
shall not cover damages caused by any other detergent. The use of any other detergent shall void this
warranty.
All repairs and replacement parts under this warranty
shall be F.O.B. G-510 CHEMICAL DIVISION’S fac-
tory. The owner shall pay the necessary freight and

510. G-510 CHEMICAL DIVISION MAKES NO OTHER
WARRANTY OF ANY KIND WHATSOEVER, EXPRESSED OR IMPLIED, AND ALL IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
FOR A PARTICULAR PURPOSE WHICH EXCEED
THE AFORESAID OBLIGATION ARE HEREBY DISCLAIMED AND EXCLUDED FROM THIS AGREEMENT. G-510 CHEMICAL DIVISION SHALL NOT BE
RESPONSIBLE FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES RESULTING FROM A
BREACH OF THIS WARRANTY.

MODEL C-6000 SERIES COMMAND CENTER - INSTRUCTIONS
General Description:
The C-6000 Command Center is designed to start and stop the
exhaust fan and wash up to 5 groups of ventilators in sequence
with a delay period between each group. A sequence wash may
be necessary if the building’s hot water system is not capable
of 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, or
may be programmed for Automatic operation.
