“GX2-UV” SERIES PRINCIPLE OF OPERATION

The Gaylord “GX2-UV” Series Non Water-Wash Ventilator
offers simplicity, economy and performance that no other
ventilator can offer. The unique “extractor insert” gives a
grease extraction efficiency far superior to that of a typical
baffle filter. The Gaylord “GX2-UV” Series Ventilators are UL
Listed and meet all the requirements of NFPA #96 and the
International Mechanical Code.

EXHAUST FAN OPERATION

The exhaust fan is controlled by the Gaylord CUV-100 Control
Cabinet. The cabinet is usually located on a wall near the
ventilator. When the control is turned on, the exhaust fan and
UV Lamps will come on.

GREASE EXTRACTION

The Gaylord “GX2-UV” Series Ventilator extracts up to 99%
of the grease, dust, and lint particles from the airstream
passing through it. Grease extraction is accomplished by
unique, removable stainless steel “extractor inserts” which
incorporate a series of horizontal baffles. As the air moves
through the extractor at high speed, it is forced to make a
series of turns around these baffles, forcing the heavier-than-
air particles of grease, dust, and lint to be thrown out of the
airstream by centrifugal force. The sticky grease collects in
the extractor and the liquified grease drains down into the
main grease gutter which slopes to the grease cup. Note:

Some ventilators may be equipped with optional “Custom Air”
baffles (shown dotted) to reduce the exhaust volume over
specific light duty cooking appliances. The extractor inserts
come in two sizes15½" (5.6 lbs.) and 19½" (6.75 lbs.).

Particulate Separator

Once the largest particles of grease have been captured
through inertial impaction by the baffles. The smaller particles
of grease will be arrested in the particulate separator using the
principles of diffusion and inertial impaction.

UV Lamps

Once the baffles and particulate separators have collected the
grease particles larger than 1 micron. The UV lights will be
able to break down the remaining grease by direct exposure
to 254nm light and by the Ozone, Hydroxyl Radicals and
Anionic oxygen created by the 187nm UV light. This will carry
down the ductwork and continue to break down the grease,
particulate and odor molecules keeping the ductwork much
cleaner. The byproducts of this process are CO2, H20 and the
base minerals from the grease and particulate matter coming
off of the cooking surface. There will be a light gray dust that
collects on the lamps, which will be need to wiped off. The
ductwork will need to be inspected per NFPA-96 schedules
but, will need much less frequent cleaning.

IMPORTANT NOTE: Never operate ventilator without extrac­tor inserts in place.

“GX2-UV” SERIES PRINCIPLE OF OPERATION

CLEANING

At the end of the cooking day the exhaust fan is turned off at
the CUV-100 control. After the fan has been turned off, the
extractor inserts and particulate separators are removed and
can be washed either in a dishwasher or soaked and rinsed
off. The grease cup is also removed and emptied at this time.
To ease in the removal of the extractor inserts, an “Extractor
Removal Tool” is available which eliminates the need for
kitchen personnel to climb up on the cooking equipment, or
up a ladder.

The UV lamps will develop a coating of dust. This coating must
be removed for optimum performance. Therefore, once a week
while the cartridges are removed, inspect the lamps and clean
as needed. Use a clean dry cloth and if necessary wash with
mild detergent and water first.

“GX2-UV” SERIES PRINCIPLE OF OPERATION

FIRE PROTECTION

NFPA-96 requires the use of Surface Fire Protection (Duct,
Plenum, Surface/Appliance) on all hoods. It is these systems
that are the first line of defense against equipment fires.

The “GX2-UV-FDD” Series ventilator incorporates a fuse link
damper at the duct collar. In the event of a fire, should the
fuse link at the duct collar reach 280°F, the fuse link melts
allowing the damper to close. (See Fig. 3) After the fire is
extinguished the fuse link(s) in the duct collar needs to be
replaced and the damper reset.

The “GX2-UV-EDD” Series ventilator incorporates an Electric
Damper at the Duct collar and 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 thermostat(s), reaches 250°F, the
Electric Damper at the Duct collar closes and the Exhaust
and Supply fans and UV Lamps shut off, when the ventilator
and fans are wired according to Gaylord’s wiring diagram.
After the thermostat(s) cool below 250°F the damper will
reset automatically, and the Exhaust and Supply fans will
restart, if the CUV-100 control is turned “ON”.

The “GX2-UV-ND” Series ventilator does NOT have a damper.
The damper in the “GX2-UV-FDD” and the “GX2-UV-EDD”

prevent the flames from entering the ductwork and spread­ing to other parts of the building. The fire is contained in the
kitchen area where it can be properly fought.

MAINTENANCE AND CLEANING INSTRUCTIONS

CLEANING

At the end of each cooking day, the exposed interior
surfaces of the ventilator should be wiped down and the
grease cup emptied. During the course of operation, grease
particles are gradually collecting inside the extractor inserts
and particulate separator. Daily, or at periodic intervals,
depending on the type of cooking, the extractor inserts and
particulate separators, must be removed and cleaned. To
clean, proceed as follows:

1. Remove extractor inserts by hand or by using the
extractor removal tool. CAUTION: Care should be
taken when removing extractors, especially over fryers.
It is recommended that the cooking equipment be
cooled down and the fryers be covered prior to removing
extractors. To remove, lift up slightly on extractor insert
and pull straight out.

2. Extractor inserts may be cleaned either by using a
dishwasher or by washing in a sink using hot water and
a degreasing detergent. Formula G-510 is highly
recommended for this application. For information

E-mail: [e-mail]

3. With the extractor inserts and particulate separators
removed, wipe and clean the back wall and the grease
gutter with hot detergent water. NOTE: If a steam or hot
water pressure washer is used for periodic cleaning of
the interior, connect a hose to the gutter drain and lead
it to a floor sink or large bucket to drain off the water.

4. To replace the extractor inserts, care must be taken to
insure that point “A” rests in the rear clip as illustrated
in Fig. 4.

5. If the ventilator(s) has a fuse link operated supply duct
fire damper NFPA-96 requires inspection of the fuse link
every 6 months and replacement annually.

6. UV lamps must be wiped down
on a regular basis. This
may need to be done
as often as weekly
on some systems.

INSPECTION AND CLEANING REQUIREMENTS

The 2001 edition of 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.

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.
Factory trained service agencies are certified by Gaylord
Industries, Inc. to perform these inspections. For the name
and phone number of your nearest agent call 800-547-9696

SAFETY CONCERNS WITH UVC

As with many types of technology if it is not used properly and/
or proper precautions are not taken there is the potential for
injury or harm. This is especially true with UVC light due to
the fact that it does not physically hurt at the time of exposure.
While UVC is very effective at breaking down grease mol­ecules, direct exposure to large amounts is harmful to skin
and eyes. The amount of UVC generated in these hoods is
greater than that what results from direct exposure to the sun.
Under no circumstances is it acceptable to view the lighted
lamps without proper eye protection or expose bare skin
directly to the light. All interlocks and safety precautions
called for in this manual must be followed to avoid the potential
for harm to service personnel and/or operators. In addition,
only trained and authorized personnel may perform some
maintenance See previous page for details.

Personal Protective Equipment

1. Eye protection that prevents 100% of UVC being trans-
mitted through the lens must be worn at all times when
performing service work on any Ultima Vent that is
energized and/or has the potential to be energized and
expose personnel to UVC light.

2. Whenever service work is performed it is recommended
that long sleeve pants and shirts be worn to minimize the
potential for inadvertent exposure of the skin to UVC.

Safety Interlocks

This product comes equipped with the following sensors to
verify that all access doors are in place and that the exhaust
fan is running:

1. Mechanical door switch on the UV Access door to ensure
that the door is closed

2. Gaylord Extractor Monitor (GEM) that ensures all of the
Extractor Inserts are installed.

3. Air Pressure switch to verify air flow and exhaust fan
operation

All of these devices must be working and/or adjusted properly
in order for the system to operate properly.

10

START-UP PROCEDURES

Before using the Ultima Vent a complete and thorough start-up of the Ultima Vent system must be performed by a qualified, and
authorized service technician. Because of this the UV modules will be shipped separate from the hood to an Certified Service
Agent(CSA). Contact Gaylord Industries to arrange for this service. It is normally included in the purchase price of the hoods.

Start-up requirements and activities

At the time of shipment a Certified Service Agent (CSA)will be
selected to perform the installation of the UV modules and the
start-up for the Ultima Vent system.

The Service agent should confirm the following prior to going
to the job site:

1. The Exhaust and Supply fan(s) are connected to the
ductwork

2. The fans have electricity and will run

3. The CUV-100 control panel is mounted and has the
following:

a. Power to the CUV -100
b. All necessary electrical connections between the CUV-

100 and the hood, surface fire protection system, and
fans.

4. All lighting wiring is connected to the hoods and light
switch

5. There is a 120 Volt, 20 Amp power circuit going to each
hood section, for UV lamps

6. Any personnel (Fire Marshal, owners rep., GC, FP
contractor, air balancer, etc) required to witness the start
up would need to be notified of time and date for start-up.

Field Start up directions

Allow about 1 hour per hood section, at the job site, for the
activities described below:

1. Check for power to the CUV-100 and wiring between the
CU V-100 and the hoods

2. Check that all Extractor Inserts are properly installed

3. Start the exhaust fan by turning the CU V-100 control on.
Both supply and exhaust fans should start. The green “UV
System On ” light should be on. If this does not occur refer
to "UV Troubleshooting" on pages 17, 18 and 20.

4. Turn CUV-100 control off. This will shut off the fans.

5. Open the UV Access door and remove the blank plate
from the UV light opening.

6. Install the UV light modules in the hood. Connect the plug
on the UV module to the hood.

7. Start the exhaust fan and check for the green “UV
System On” light at the hood(s) and control panel. Make
sure that all access doors are closed.

8. Check the air velocity at the inlet slot

9. Record the data on the start up form. Determine the
correct inlet slot velocity and record that in the design
velocity location. Then determine the percentage of de­sign that the actual air velocity represents

11. Remove an Extractor Insert

a. The red “Safety Interlock Activated” lamp should come on

and an audible alarm sound.

12. Check the UV Access door interlock

a. Open the UV Access door with the fan on.The red

“Safety Interlock Activated” lamp should come on and
an audible alarm sound.

Caution: Before any Fire tests are performed, check with
the building superintendent to see if the Surface Fire
Protection system is wired to the building alarm, monitor-
ing system, and/or fire department.

13. If the FP contractor is there have them trip the micro
switches on the FP system to verify that the Exhaust
Fan(s) starts and supply Fan(s) shut off.

14. Once all is working correctly demonstrate the following to
the end user

a. If the hood is interlocked with the FP system. Have the

FP contractor test it and confirm that the External fire
mode works properly.

b. Instruct them that if for any reason they can see the UV

light directly they must shut off the hood immediately
and call a CSA.

c. Check for proper damper operation if this hood has a

damper
d. How to remove, clean and replace the Extractor Inserts
e. That they need to perform the required end user main-

tenance described in the tech manual and hire CSA to

perform the UV maintenance as described in the tech

manual and have the duct system inspected/or cleaned

per the requirements of NFPA-96.
f. The frequency will need to be adjusted based on the

type, amount and duration of cooking done at this site.
q. Fill out the start up form completely with comments
r. Notify the Dealer/customer if the air volumes are more

than 5% low or 10% high and give the dealer and GC

a copy of the Start-up report.
g. Send a copy of the Start-up report to Gaylord and keep

a copy for your records.

MEASURING INLET SLOT VELOCITY

MEASURING INLET SLOT VELOCITY

Smoke capture and grease extraction efficiency are de­pendent upon the proper air velocity at the inlet slot of the
ventilator.The required average slot velocities are shown
on the “Air Velocity Chart” below. If the slot velocity is
below the required average, the exhaust fan must be
adjusted accordingly.

NOTE: The height of the inlet slot can vary depending
upon the design of the ventilator. It is, therefore, important
to first measure the inlet slot and compare it to the chart
below to determine the required average inlet slot veloc­ity. The designed CFM per lineal foot is related to the
velocity as shown on the chart below. The total CFM for
the ventilator can be found on the ventilator nameplate.
(See Figure 6).

Air velocity readings less than what is specified on the “Air
Velocity Chart” may allow smoke and grease to escape
the confines of the ventilator and/or reduce grease extrac-
tion efficiency. This can result in grease deposits which
lead to sanitation problems or fire hazards if left uncor­rected. If air velocity readings are higher than those
specified, it will require more energy to operate the
exhaust fan and excessive noise levels will result. Higher
or lower velocities than the required average will normally
put the entire heating and ventilating system out of bal­ance. When measuring the air velocity it is very important
to take an average reading across the inlet slot plane as
described on Page 13. Positioning the sensing head
incorrectly will give velocity readings that cannot be com­pared to the “Air Velocity Chart”.

FIG. 5B

MEASURING INLET SLOT VELOCITY

The standard instrument used for measuring the inlet velocities on a Gaylord
Ventilator is a Pacer, Model DA40 or DA4000 Digital Anemometer. This
instrument is the easiest, most accurate and the best suited for measuring
ventilator inlet slot velocities. To take accurate air velocity readings, follow
the instructions below.

Instructions

1. It is first necessary to determine if the ventilator includes Custom Air baffles
as shown in Fig. 5B. If shop drawings are available, and if equipped, the
custom baffles and their location will be noted on the front elevation. If not
available, to determine if Custom Air baffles are provided run your hand along
the bottom inlet slot and feel for the Custom Air baffle as illustrated in Fig. 5B.

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

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

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

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

6. Using the 16 second averaging feature on the meter, slide the sensing head along
the slot, back and forth, for a 3'-0" to 4'-0" distance, and record the velocity at the end
of the 16 second mark. Continue this process for the full length of the ventilator.

Important Note: If the ventilator includes custom air baffles as illustrated in Fig.
5B, always take separate readings on the section of the ventilator that includes
custom air from the section that does not have the baffles. Non custom air and
custom air readings must be recorded separately. Do not average them together.

Important Note: On the rear slot of a Model BDL-DS Series, do not use the
guide bracket. Refer to Figure 5C.

7. Record the velocity (fpm) on the start up inspection report form. A sample
report form, which can be photocopied, is provided on page 16.

8. The designed, or optimum velocity, is noted on the shop drawings and
the Air Velocity Chart on page 12. Two velocities will be noted if the ventilator
includes custom air baffles.

9. Compare the recorded air velocity to the designed air velocity shown on the
shop drawings or the Air Velocity Chart on page 12. The recorded velocity may
be slightly lower or higher providing that it is within the minimum and maximum
range as shown on the Air Velocity Chart .

If the air velocity is outside the minimum/maximum range, the performance of
the ventilator will be affected and therefore the exhaust fan must be adjusted.

MODEL “MAW” SERIES

FRONT FACE DISCHARGE

This method of introducing make-up air into the
kitchen is flexible and has many advantages.
Make-up air is discharged through stainless steel
perforated panels as illustrated (MAW Series) or
optional registers (MAR Series). Typical supply
volume is 80% of the exhaust or more, depend­ing on air balance desired. Supply air tempera­tures should range from 60 to 65°F (16 to 18°C),
but may be as low as 50°F (10°C) depending on
air volume, distribution, and internal heat load.

MODEL “MAI” SERIES

INTERNAL DISCHARGE

This method of introducing air into the hood is
typically referred to as the “short circuit” method.
This design has very limited applications and
the amount of supply air able to be introduced
varies considerably with the type of cooking
equipment. This air may be untempered air in
most areas depending upon climatic conditions
and the type of cooking equipment. The differ­ence between the quantity of air being intro­duced and the amount of air being exhausted
must be supplied through a traditional make-up
air system.
