FAN OPERATION

To operate the exhaust fan turn on the fan switch that is typi­cally mounted on a wall near the hood. The “XG” hood may
be equipped with a fan, auto start controller, and/or light switch
mounted on the face of the hood.

GREASE EXTRACTION (XG EXTRACTORS)

The Gaylord Industries Patent Pending XG Extractor Cartridge
is designed to deliver the absolute optimum in collection ef­ciency at the lowest possible pressure drop. The units are ETL
listed to UL 1046 standard, and are also recognized as part of
an XG Ventilator. They are constructed of corrosion resistant
stainless steel and feature a GX style handle for easy removal
from the ventilator to which they are mounted. Another great
feature of the XG lter is that it can be opened up and turned
back on itself for easy and efcient dishwasher cleaning. The
opening of the lter is accomplished by a top mounted, dual
hinge and a set of snap buttons at the bottom to secure the
lter in position. The benet to such a design ensures that
restaurant employee’s will always have access to the inside of
the extractors for easy cleaning, and will not mistakenly install
the units in the opened, or disassemble position.

CLEANING

At the end of the cooking day, or at periodic intervals, cartridges
are removed and washed either in a dishwasher or soaked in
a deep well sink, scrubbed and rinsed.

OPERATION

FIRE PROTECTION

NFPA #96 requires the use of surface, duct and plenum pro-
tection on all hoods.

These systems are designed to detect and extinguish res on
the cooking surface, within the plenum and at the duct collar.
Refer to the re extinguishing system owner’s manual for opera-
tion and maintenance instructions of these systems.

The “XG-GFBD” hood is equipped with an exhaust duct re
damper. In the event of a re, should the thermostat reach its
activation point of 325° F, the damper would close preventing
the ames from entering the ductwork and spreading to other
parts of the building. The re is contained in the kitchen area
where it can be properly fought.

The hood may be supplied without a re damper which is
designated by the sufx “ND” in the model number or with a
Balancing Only damper denoted with a “GBD” in the model
number. Refer to the nameplate on the hood for the exact
model number. (See Figure 7, page 5).

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 cartridge
extractors. Daily, or at periodic intervals, depending on the type of cook­ing, the cartridge extractors must be removed and cleaned. To clean,
proceed as follows:

1. Remove lters. CAUTION: Care should be taken when removing
lters, especially over fryers. It is recommended that the cooking
equipment be cooled down and the fryers be covered prior to removing
lters. To remove, lift up slightly on lters 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. Prior to cleaning, open the XG extractor to gain access
to the lters interior. Formula G-510 is highly recommended for this
application. For information contact:

3. With extractors removed, wipe and clean the back wall and top of the
plenum area and the grease gutter with hot detergent water. NOTE: If
steam or hot water pressure wash is used for periodic cleaning of the
interior, remove the grease drawer and connect a hose to the gutter
drain and lead it to a oor sink or large bucket to drain off water.

4. Replace extractors. Be sure to replace extractors with bafes running
vertical as shown in Fig. 5.

IMPORTANT NOTE: In the event of a re the thermostat must be replaced.
(Applicable to GFBD models only.)

ETL Listed Nameplate

The total minimum required exhaust
volume can be found stamped on
the ETL nameplate located on each
hood section. Minimum listed values
do not always correspond to the
design requirements for each hood
section.

MEASURING AIRFLOW

Measuring Airflow

The XG hood has been designed to give you
an approximate airflow per linear foot of hood
based on the static pressure measured at a
particular location on you XG hood section.
The method will require the balancer to have a
manometer, (Dwyer 475-00 FM
recommended), which he/she will use to get a
static pressure measurement for every hood
section. The static tap, as seen in fig. 8, will be
located behind a small 4 to 6 screw access
cover, located directly above your f

ilters.

Instructions:

1. Turn on the exhaust fan to the hood
section you intend to measure the
exhaust airflow.

2. Remove access cover as seen in fig. 8.

3. Locate the static tap, and remove the
sealing boot.

4. Zero you Dwyer 475-00 Digital
Manometer.

5. Take the 1/8” vinyl tube attached to your
Dwyer 475-00 Digital Manometer and
attach it to the static tap.

6. Record the value indicated on your
meter.

7. Compare your recorded values to Fig. 9,
Airflow vs. Static Tap Chart to determine
your rate of

flow

for the hood per unit length
of the hood. Total flow will be the CFM/LF
obtained from Fig. 9 multiplied by the
length of the ventilator section.

8. Design values will be noted on the
listing label attached to the inside of the
ventilator, or sticker attached to the
inside of the access cover.

Fig. 9, Airflow vs. Static Tap Chart

Balancing

Hood system flow rates are to be adjusted to
obtain the correct pressures noted above. Flow
adjustment for the XG ventilator is to be done by
either manipulation of the Gaylord Industries
GBD, or GFBD balancing dampers, or by fan
pulley adjustment. Reference your GBD/GFBD
technical manual for more details

Consult the Gaylord Industries factory for Listed,
and recommended airflow rates over particular
equipment line up, as well as best practice
system balancing, and

equipment place.
