OPERATION
FAN OPERATION
To operate the exhaust fan turn on the fan switch that is typically mounted on a wall near the hood. The “PG” hood may
be equipped with a fan and/or light switch mounted on the
face of the hood.
GREASE EXTRACTION
The Gaylord “PG” Series Hood, as a standard, utilizes UL Classified filters to extract the grease from the airstream. The filter
is a self-balancing baffle type and is constructed of aluminum
or stainless steel. Typical grease extraction rate varies between 40% and 65%.
The hood may be equipped with optional extractor cartridges,
as shown in figure 6 page 3, that have a grease extraction
efficiency of up to 90%. When equipped with cartridges, the
model number prefix is “PGX”. Refer to the nameplate on the
hood for exact model number. (See Figure 7, page 5.)
CLEANING
At the end of the cooking day, or at periodic intervals, the filters
or cartridges are removed and washed either in a dishwasher
or soaked in a deep well sink, scrubbed and rinsed.
GREASE EXTRACTION
FIRE PROTECTION
NFPA #96 requires the use of surface, duct and plenum
protection on all hoods.
These systems are designed to detect and extinguish fires on
the cooking surface, within the plenum and at the duct collar.
Refer to the fire extinguishing system owner’s manual for
operation and maintenance instructions of these systems.
The “PG” hood is equipped with an exhaust duct fire damper.
In the event of a fire, should the fuse link reach its activation
point of 212 °F, the damper would close preventing 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.
The hood may be supplied without a fire damper which is
designated by the suffix “ND” in the model number. Example:
“PG-ND”. Refer to the nameplate on the hood for the exact
model number. (See Figure 7, page 5).

FIGURE 3
FRONT FACE DISCHARGE
Standard Make-up Air
Options
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. 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.
2
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.
MAINTENANCE AND CLEANING INSTRUCTIONS
At the end of each cooking day, the exposed interior surfaces of the
hood should be wiped down and the grease cup emptied. During the
course of operation, grease particles are gradually collecting inside
the filters or optional cartridge extractors. Daily, or at periodic intervals, depending on the type of cooking, the filters or cartridge extractors must be removed and cleaned. To clean, proceed as follows:
1. Remove filters. CAUTION: Care should be taken when removing
filters, especially over fryers. It is recommended that the cooking
equipment be cooled down and the fryers be covered prior to removing filters. To remove, lift up slightly on filters and pull out at the
bottom, then straight down.
2. Filters may be cleaned either by using a dishwasher or by soaking in
deep well sink using hot water with a degreasing detergent, scrubbed
and rinsed. Formula G-510 is highly recommended for this application. For information contact:

3. With filters removed, wipe and clean the back wall and top of the
plenum area and the grease gutter with hot detergent water. NOTE:
If a steam or hot water pressure is used for periodic cleaning of the
interior, remove the grease cup and connect a hose to the gutter
drain and lead it to a floor sink or large bucket to drain off water.
4. Replace filters. Be sure to replace filters with baffles running vertical
as shown in Fig. 5., or if cartridge extractors are used, the inlet slot is
at the top as shown in Figure 6.
If the hood is equipped with either an exhaust or supply fire damper,
which is located at the duct collar, NFPA #96 requires that the fuse link
be inspected semi-annually and replaced annually. It is recommended
that a professional service organization be contracted to perform this
service. Normally, this could be the same company that services the fire
protection system. IMPORTANT NOTE: All exhaust fire damper
replacement fuse links must be UL Listed and rated for 212°F (100°C)
and all supply fire damper replacement fuse links must be UL Listed and
rated for 165°F (74°C).
FIGURE 5
NOTE: FILTERS MUST BE INSTALLED WITH
BAFFLES RUNNING VERTICAL AS SHOWN.
INSPECTION AND CLEANING REQUIREMENTS
CAUTION: Care should be taken when removing
filters, especially over fryers. It is recommended
that the cooking equipment be cooled down and
the fryers be covered prior to removing filters.
The 1998 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 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.

1. Inspect duct system and verify that there
are no other non hood systems tied in. If
so they must be removed.
C. Improperly placed make-up air diffusers.
1. Make-up air directed at the hood will likely
create cross drafts disrupting the air flow
into the hood. Adjust the louvers to direct
the make-up air away from the hood.
2. Make-up air should be delivered through
registers at ceiling height, and distributed
throughout the kitchen area.
3. M a k e - u p a i r r e g i s t e r s l o c a t e d n e a r t h e

hood typically creates cross drafts
resulting in smoke loss.
D. Inadequate make-up air.
1.
Make-up air must be supplied for
replacement of air exhausted through all
kitchen exhaust systems. A general "rule
of thumb" is that 75% to 80% of the
replacement air should be fresh,
conditioned, (heated or cooled) air
brought into the kitchen area, with the
remaining 20% to 25% allowed to flow into
the kitchen from adjacent areas.

MEASURING BAFFLE FILTER VELOCITY
MEASURING FILTER VELOCITY
Smoke capture and grease extraction efficiency are dependent upon the
proper air velocity at the filter.
The designed air volume for the “PG” Series hood varies between 150
and 500 CFM per lineal ft. depending upon the type of cooking equipment, and style of hood. Refer to the “Filter Velocity Charts” below. Filter
sizes are determined by the designed CFM per lineal ft. The average
velocity (FPM) taken at the face of the filter should be within the range
shown on the charts. If the velocity is below or above the required average, the exhaust fan should be adjusted accordingly.

The standard instrument used for measuring the filter velocities on a
Gaylord Hood is a Pacer, Model DA40 or DA4000 Digital Anemometer.
This instrument is the easiest, most accurate and the best suited for
measuring filter inlet velocities. To take accurate air velocity readings,
follow the instructions below.
Instructions
1. Attach the cable from the sensing head to the meter and the handle
sections to the sensing head.
2. Place the sensing head against the filter as illustrated in figures 8
and 9.
3. Using the 16 second averaging feature on the meter, slide the head
across one or two filters, as illustrated in figure 8, until the 16 second
average has elapsed.
4. Record the velocity (fpm) on the start up inspection report form. A
sample report form, which can be photocopied, is provided on page 10.
Continue this process for each of the filter sets.
5. Average the velocities and compare to the air velocity shown on the
Filter Velocity Chart. The average velocity may be slightly lower or higher
providing that it is within the minimum and maximum range as shown on
the Filter Velocity Chart.
If the air velocity is outside the minimum/maximum range, the performance of the hood will be affected and therefore the exhaust fan must be
adjusted.

5. Using the 16 second averaging feature on the meter, slide the sensing
head along the slot, back and forth, accross two or three cartridges, and
record the velocity at the end of the 16 second mark. Continue this process
for the full length of the hood.
Imortant Note: If the hood includes custom air baffles as illustrated in Fig.
11, always take separate readings on the section of the hood that includes
custom air from the section that does not have the baffles. Non custom air
and custom air readings must be recorded seperately. Do not average
them together.
6. Record the velocity (fpm) on the start up inspection report form. A
sample report form, which can be photocopied, is provided on page 10.
7. The designed, or optimum velocity, is noted on the shop drawings and
the Inlet Velocity Chart. Two velocities will be noted if the ventilator
includes custom air baffles.
8. Compare the recorded air velocity to the designed air velocity shown
on the shop drawings or the Air Velocity Chart. The recorded velocity may
be slightly lower or higher providing that it is within the minimum and
maximum range as shown on the Inlet Velocity Chart .
If the air velocity is outside the minimum/maximum range, the performance of the hood will be affected and therefore the exhaust fan must be
adjusted.
Smoke capture and grease extraction efficiency are dependent upon the
proper air velocity at the inlet slot of the cartridge extractors. 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 designed air volume. 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 hood nameplate. (See Figure 7,Page 5).

Air velocity readings less than what is specified on the “Inlet Velocity
Chart” may allow smoke and grease to escape the confines of the ventilator and/or reduce grease extraction 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 in the instructions. Positioning the sensing head incorrectly will give velocity readings
that cannot be compared to the “Inlet Velocity Chart”.
FIGURE 11
The standard instrument used for measuring cartridge extractor inlet
velocities on a Gaylord Hood is a Pacer, Model DA40 or DA4000 Digital
Anemometer. This instrument is the easiest, most accurate and the best
suited for measuring hood inlet slot velocities. To take accurate air velocity
readings, follow the instructions below.
Instructions
1. It is first necessary to determine if the hood includes Custom Air baffles
as shown in Fig. 11. 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, remove one or
more cartridge extractors and look along the bottom cartridge track for a
Custom Air baffle as shown in Figure 11.
2. If the hood includes Custom Air baffles, it will be necessary to take two
sets of readings - one for the section of hood that includes Custom Air
baffles and one where it does not.
3. Attach the cable from the sensing head to the meter and the handle
sections to the sensing head.
4. Place the sensing head against the lower lip of the cartridge inlet slot
as illustrated in Figure 11 and 12.
