"CG" SERIES VENTILATOR PRINCIPLE OF OPERATION
GREASE EXTRACTION
The Gaylord “CG” 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 four baffles.
As the high velocity air turns around each baffle, the heavierthan-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 of
airplane wing type construction, and in its normally open
position, acts as the primary extracting baffle. (Refer to Figure
1) This baffle is hinged at each end and, in case of fire, is
automatically closed by thermostatic action. There is a small
sloped grease collecting gutter on the back side of the damper
which drains off liquefied grease, preventing it from re-entrain-
ing 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.
Baffle #4
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. Baffle #4 is inter-connected with
baffle #2, and performs washing and fire protection functions
simultaneously with baffle #2.
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 25 for details.

"CG" 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, if equipped with optional time clock (“TC” Series), as
programmed on the clock. The “Wash On” light is illuminated
each time the wash cycle comes on, and hot, detergent
injected water is released into the interior of the ventilator for
the time set on the wash timer.
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 two wash pipes (BAFFLES)
mounted on the interior back wall of the ventilator. (Refer to
Figure 3) At the end of the wash cycle, the water is
automatically shut off, and the interior of the ventilator is clean
- ready for the next day’s operations.
There are three standard wash cycle times that are set
depending upon the type of cooking equipment being used.
COMMAND CENTER
MODEL C-5000
SERIES
The 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 accumula-
tion, 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 the next higher setting to achieve
proper cleaning.

350°F THERMOSTAT
INTERNAL FIRE MODE
Automatic internal fire protection is accomplished by the
action of the thermostats, 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 350°F (177°C), the system is activated, and the
following occurs:
1. The hinged, grease-extracting fire damper baffle at the air
inlet of the ventilator closes — stopping the combustionsupporting, natural draft through the ventilator. (Refer to
Figure 6)
2. The exhaust fan serving the ventilator is shut off, stopping
the combustion-supporting, mechanically induced draft.
The supply fan is also shut off.
3. Fire-smothering water spray is released into the interior of
the ventilator through the cleaning system.
4. The “Fire” light on the Command Center illuminates.
Water will run until the thermostat cools below 350°F (177°C),
and then continue for a 5 minute cool down cycle. The water
may be shut off prior to the end of the 5 minute cool down cycle
by pushing the “Cancel” button located inside the electrical
compartment of the control cabinet. After the water has shut
off, the dampers can be reset by pushing the reset handle on
the damper control switch (Refer to Figure 5), and the exhaust
fan(s) re-started by pushing the “Start Fan” button on the
Command Center.
EXTERNAL FIRE MODE
A break glass fire switch is optional (see Figure 4) and if
provided, would normally be located at the exit of the kitchen.
Pulling the fire switch shuts off the supply fan and starts the
exhaust fan if it was off, releases fire smothering water spray
into the interior of the ventilator and the “Fire” light on the
Command Center flashes. During this time, the fire damper
remains open, and the exhaust fan remains on to help remove
smoke, heat, etc. If the fire intensified and the thermostat
reached 350°F, the fire damper would then close and the
exhaust fan would shut off.
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.

TESTING INTERNAL FIRE MODE
The internal fire protection system may be tested periodically
by pushing the “Fire Test Switch” which is 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 5 minute cool down cycle at any point
during the cycle, push the “Cancel” button located inside
the electrical compartment.
2. Reset all damper control switches.
3. Push the “Start Fan” button on the Command Center.
SURFACE FIRE PROTECTION
The Gaylord Ventilator may be equipped with surface fire
protection either dry or wet chemical, or the Gaylord Quencher
System. In the event of a fire, the surface fire protection
system would normally be activated and discharged prior to
the ventilator’s internal fire protection. These systems may be
intertied with the ventilator control cabinet to activate the
External Fire Mode. 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.

"RG" SERIES VENTILATOR PRINCIPLE OF OPERATION
GREASE EXTRACTION
The Gaylord Royal “RG” 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 is located at the air inlet of the ventilator and is
formed as part of the inspection door. There is a small grease
collecting gutter on the back side of the baffle which drains off
liquefied grease, preventing it from re-entraining into the
airstream.
Baffle #2
This baffle is on the interior back wall of the ventilator and
includes a square stainless steel pipe, equipped with brass
spray nozzles on 8" to 10" centers. 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 door.
NOTE: Some ventilators may be equipped with optional
“Custom Air” baffles (shown dotted) which reduces the exhaust volume where the baffles occur.
NOTE: Some ventilators may be equipped with optional
continuous cold water mist. Refer to Page 25 for details.

operations.
There are three standard wash cycle times that are set
depending upon the type of cooking equipment being used.
On fuse link activated ventilators, water will continue to run
until it is shut off by the hand valve located inside the
ventilator control cabinet. The fire damper must then be
reset by replacing the fuse links. IMPORTANT NOTE: All
replacement fuse links must be UL Listed and rated for 280°F
(138°C).
The hand valve may then be reopened and the exhaust fan
may then be re-started by pushing the “Start Fan” button on
the Command Center.

Starting the Exhaust Fan
To start the exhaust fan push the “Start Fan” button on the
Command Center. If the Command Center is equipped with a
time clock (“TC” Series control), it may be programmed to start
automatically at any desired time. (Refer to programming
instructions on Page 15 for automatic operations.) The “Fan
On” light will illuminate when the exhaust fan is running. It is
important to start the exhaust fan before turning on the cooking
equipment.
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.
1. To start the wash cycle push the “Start Wash” button
on the Command Center. If the Command Center is
equipped with a time clock (“TC” Series control), it may be
programmed to start automatically at any desired time.
Refer to programming instructions on Page 15 for auto-
matic operations. When the wash cycle is activated the
“Wash On” light illuminates and the following occurs:
A. The exhaust fan shuts off.
However, adequate cleaning is dependent upon water
pressure, water temperature, daily grease accumulation, the length and frequency of the wash cycle, and
the type of detergent being used. Refer to wash timing
instructions on Page 14 for setting the length of the
wash cycle.
NOTE: Some control cabinets are equipped with a
low detergent switch. If so equipped, the “Wash On”
light will flash if the detergent tank is empty or if the
detergent pump is malfunctioning and detergent is not
pumping.
2. After the wash cycle is completed, wipe the exposed front
surface of the baffle at the air inlet of the ventilator, as well
as other exposed exterior surfaces. (Refer to Figure 15)
3. The ventilator is now clean. The exhaust fan may be
restarted by pushing the “Start Fan” button on the
Command Center.
In very heavy cooking operations it may be necessary to wash
the ventilator(s) more than once a day. If equipped with a time
clock (Model C-5000-TC Series) the Command Center is
capable of being programmed to start the wash cycle several
times within a 24-hour period. Refer to programming instruc-
tions on Page 15.
NOTE: For proper operation of the wash system:
Water Pressure 40 psi min. - 80 psi max.
(2.8Kg/cm2 - 5.6Kg/cm2)
Water temperature 140°F min. - 180°F max.
(60°C min. - 82°C max.)
NOTE: The ventilator wash system is designed to remove daily
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.
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.
B. Hot detergent water is automatically released into the
interior of the ventilator for the length of time set on the
wash timer. The length of the wash cycle may be set
for 3 different wash times, 3 minutes for light-duty
equipment, 5 minutes for medium-duty equipment,
and 9 minutes for heavy-duty equipment.

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 12)
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 15) If overall cleaning appears to be
inadequate, refer to “Trouble-Shooting of the Wash Sys-
tem”, Page 19.
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 necessary
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 22
through 24 for method of checking velocity.
3. Test the "Internal Fire Mode" (electrically activated
dampers only) to check for proper damper closure. Refer
to page 5. Reset damper when test is complete.
4. Detergent tank and foot valve should be cleaned every six
months.
NOTE: Annual and semi-annual inspections are
recommended by the NFPA, Standard No. 96, Chapter 8.

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 “Wash On” light will
flash if the detergent tank is empty or if the detergent pump is
malfunctioning and detergent is not pumping.
Initial Operation
To prime and operate the pump for the first time, it is
recommended 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.
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.
DETERGENT FLOW
Detergent flow is initially factory set according to the pipe size
of the 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 5. Frequency of wash
2. Water pressure cycle
3. Daily grease accumulation 6. Type of detergent
4. Wash cycle time
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.

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
redeposit 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 deposits 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, sul-
fonates 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

This is the sole warranty with respect to FORMULA
G-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.
IMPORTANT
