INSTALLATION

General

1. Carefully remove unit from carton or crate. Burner tie
wires and other packing material should be removed
from units. On stainless steel units, the protective
material covering the stainless steel should be removed
immediately after the unit is installed.

2. Remove top grates and place in a safe area to prevent
damage.

3. Should it be necessary to remove the steel griddle plate
on units equipped with griddle thermostats, the griddle
thermostat bulb and capillary must rst be withdrawn
from the bulb shield assembly, located on the underside
of the griddle plate. This can be accomplished with the
griddle front raised and supported by the griddle prop
located on the underside of the griddle plate. Loosen the
four pal nuts securing the bulb shield assembly to the
griddle plate and withdraw the griddle thermostat bulb.

4. When a griddle plate is being installed on units equipped
with griddle thermostats, the thermostat bulb must
be inserted in the groove between the plate and the
bulb shield assembly. This can be accomplished with
the griddle front raised and supported by the griddle
prop, located on the underside of the griddle plate. It is
important for accurate temperature control that the bulb
be located inside the groove. Tighten the four pal nuts
securing the bulb shield assembly to the griddle plate.

5. These units must be installed under an adequate
ventilation system. Refer to section titled Ventilation for
further instructions.

INSTALLATION Continued

Gas Connections

1. The installation and connection must comply with local
codes, or in the absence of local codes, with CAN/CGA­B149 Installation Code or with the national Fuel Gas Code,
ANSI Z223.1/NFPA No. 54 – Latest Edition.

2. The correct type of gas for which the unit was
manufactured is noted on the rating plate, and this type
of gas must be used.

3. The gas pressure must be checked when the unit is
installed, to ensure that the unit gas pressure is the same
as specied on the rating plate. If necessary, pressure
adjustments can be made at the pressure regulator,
supplied on each unit.

4. Have a qualied gas technician check the gas pressure
to make certain that existing gas facilities (meter, piping,
etc.) will deliver the BTU’s of gas required at the unit with
no more than ½” water column pressure drop. When
checking pressure, be certain that all the equipment on
same gas line is turned to the “ON” position.

5. The appliance and its individual shut o valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of 1/2 PSIG. (3.45 KPA).

Leg Installation

The leg channel is located on the package base. This channel
must be installed when using the legs.

6. The appliance must be isolated from the gas supply
piping system by closing its individual manual shut o
valve during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2 PSIG.
(3.45 KPA).

7. Make certain that the new piping, joints and connections
have been made in a clean manner and have been
purged, so that the piping compound, chips, etc., will not
clog pilots, valves and/or controls. Use pipe joint sealant
that is certied for use with liqueed petroleum gas.

8. WARNING: Check gas connections for leaks, using soap
solution or similar means. Do Not Check with an Open
Flame.

LEG INSTALLATION

Installation of Banking Plates

All units may be installed independently or banked with
other GD or ED Series equipment. To ensure a matching
and permanent t between units, two banking plates are
available for each unit to be installed. One at the front and
one at the rear of each two units being banked together.

1. Level each unit by adjustment of leveling bolts or legs.
Use a spirit level and level unit four ways; across front and
back and down left and right edges. Level all other units
to the rst unit.

INSTALLATION Continued

Note: Griddles may not rest evenly on the unit body if units
are not leveled.

2. Remove sheet metal screws at rear of unit.

3. Attach one banking plate in position at rear by placing
the 1/4” (6 mm) diameter holes in the banking plate
over the screw holes in the rear of units and fasten by
replacing the sheet metal screws removed in Step 2.

4. Push units into position on counter top or back bar.

5. Remove the two acorn nuts from the sides being banked
(one for each control panel). Place banking plate over
the two protruding screw heads, replace acorn nuts and
tighten.

2. Remove and discard leveling bolts on unit to be installed
on a non-combustible counter stand.

3. Place units in desired position on counter stand, securing
the rst unit with 8-32 machine screws and at washers.
Insert 8-32 machine screws through the 7/32” (5 mm)
diameter holes in stand into the nutserts in the bottom of
GD Series units.

4. Connect banking plates as described in section titled.
Installation of Banking Plates.

5. Secure last unit to counter stand with 8-32 machine
screws and at washers. Insert 8-32 machine screws
through the 7/32” (5 mm) diameter holes in stand into
nutserts in the bottom of GD Series units

Ventilation

Counter equipment must be installed in a location in which
the facilities for ventilation permit satisfactory combustion
of gas and proper venting. Proper ventilation is imperative
for good operation of the appliance. The ideal method
of ventilating counter equipment is the use of a properly
designed ventilating canopy, which should extend at least
6”/152mm beyond all sides of the appliance (except against
the wall if the canopy is a wall installation). This is usually part
of a mechanical exhaust system.

Air Supply

FRONT VIEW

Installation of Non-Combustible
Counter Stands (Optional)

1. Assemble and level counter stand as illustrated in the
instructions found in the counter stand carton.

1. It is necessary that sucient room air ingress be allowed
to compensate for the amount of air removed by any
ventilating system. Otherwise, a subnormal atmospheric
pressure will occur, aecting the appliance operation
adversely and causing undesirable working conditions.

2. Appliances shall be located so as not to interfere with
proper circulation of air within the conned space. All gas
burners and pilots require sucient air to operate.

3. Large objects should not be placed in front of the
appliance which might obstruct the air ow through
the front. Do not obstruct the ow of combustion and
ventilation air.

4. Do not permit fans to blow directly at the appliance, and
wherever possible, avoid open windows adjacent to the
appliance sides and back; also wall type fans which create
air cross-currents within the room.

ADJUSTMENTS

Burner Adjustments – All Units

1. Before making any adjustment, turn all gas valves
to “OFF”. Remove the burner tie wires, if not already
removed. Be sure all piping is gas tight and that air is
purged from lines.

2. All units are shipped from factory at burner ratings set
for the gas specied on the rating plate at normal gas
pressure. The only adjustment necessary is for that
governing air.

Air Adjustment: If necessary, the air is adjusted by rotating
the air shutter on burner. The burner must have enough air
that the tips of the ames are not yellow, but not so much air
that the ames will lift o the burner ports. Securely tighten
air shutter screw so air shutter cannot be moved.

Hot Plates

IMPORTANT: The ue must be installed prior to start-up.

Pilot Burner Adjustment

Each burner in the hot plate is equipped with a pilot. The
burner pilot is ignited by the piezo ignitor located behind the
front door.

The pilot has been adjusted at the factory; however, it may
require adjustments once installed. The pilot adjusting valve
is located under each burner valve.

Open the bottom door and use a long thin straight blade
screwdriver to adjust the valve. Refer to Flame Size Chart.

Burner Operation

The burner will light automatically from the pilot. Turn the
valve to the full “ON” position. Once the ame has ignited,
adjust the valve to the desired setting.

Fryers

Before Operating the Fryer

1. Before leaving the factory, the fryer was tested and the
thermostat calibrated with oil in the fry tank; therefore, it
is necessary to clean the fry tank before lling with frying
compound. Use detergent or other cleaning agents, with
hot water. Thoroughly rinse and dry fry tank.

2. BEFORE LIGHTING THE PILOT, ll the fry tank. NEVER
OPERATE THE PILOT OR BURNER WITH AN EMPTY FRY
TANK. It only takes a few minutes to completely ruin a fry
tank and void the warranty.

3. WARNING: When fryers are in use, fryer restraint chains/
cables must be installed in order to prevent the fryer from
tipping and splashing hot liquid. Hot shortening causes
severe burns. Never attempt to move a fryer when the
frypot is full. Drain frypot completely before moving fryer.

Pilot Burner Adjustment

1. Turn thermostat knob to lowest position.

2. Depress and turn automatic gas valve knob to “OFF”
position. Caution: Wait 5 minutes before lighting or
relighting pilot.

3. Turn automatic gas valve knob to “Pilot” position.

4. Push knob in, light pilot, and continue to hold knob in for
about 60 seconds after pilot light is lit.

5. Adjust pilot ame to 3/4” (19 mm).

6. If pilot does not continue to burn after releasing button,
repeat above procedure or…

7. Have a qualied Serviceman check the system. DO NOT
ALLOW ANYONE ELSE TO ATTEMPT REPAIRS.

To Operate Main Burner

1. If liquid frying compound is used, the main burner may
be turned on.

2. To ignite burner, turn automatic gas valve
counterclockwise to the “ON” position.

3. If a Hydrogenated (SOLID) frying compound is used,
pack the tank with compound and turn the main burner
on for approximately ve seconds and turn it o for
approximately ten seconds. Repeat until compound
is melted. If any smoke is seen during the process, the
heating action is being carried out too fast and the
frying compound is being scorched as well as possibly
damaging the fry tank.

ADJUSTMENTS Continued

Shutdown Instructions

To shut down fryer for a short period, turn automatic gas
valve knob to the “PILOT” position.

For complete shutdown, turn automatic gas valve knob
clockwise to “PILOT” position, depress the knob, turn slightly
clockwise, release, and continue to turn clockwise to “OFF”.

Calibration Instructions

1. Field calibration is seldom necessary and should not
be attempted unless experience with cooking results
denitely proves that the control is not maintaining the
temperature to which the dial is set.

2. Suspend thermometer or thermocouple in the middle
of the fry tank, approximately 2” (51 mm) below the
shortening level.

3. Allow burner to cycle at least four times.

4. When the burner just cycles o after the fourth cycle,
compare reading of the thermometer or thermocouple
with thermostat setting.

5. If the two do not agree, ± 10°F (5°C), loosen the two set
screws on the thermostat knob.

6. Set the pointer at the temperature indicated by the
thermometer.

7. Tighten the set screw rmly.

8. Ensure the back surface of the knob is spaced away from
the dial plate at least the thickness of a dime.

NOTE: Do not turn adjusting shaft more than two turns in
either direction or permanent damage can result. This action
will void the Standard Fenwal thermostat warranty.

Griddles

IMPORTANT: The ue must be installed prior to start-up.

For the griddle equipped with thermostats the pilot and the
main burner are controlled by the ON-OFF valve. MAKE SURE
THE THERMOSTAT IN ON OFF POSITION. Turn on the main
valve and light the pilot with a match. The pilot adjusting
screw is located at the bottom of the thermostat.

Pilots ames must be 3/4 inch (19mm) long

Burner Operation

The burner will light automatically from the pilot. Turn the
valve to full “ON” position. Once the ame has ignited, adjust
the valve to the desired setting.

Hi-Lo Valve Adjustment

Griddles equipped with Hi-Lo valves require a low ame
setting. To adjust, proceed as follows:

1. Burner must be cold.

2. Be sure pilot ames are lit, and adjusted.

3. Turn dial to “LO” position, then remove dial.

4. With a screwdriver, turn the small adjusting screw inside
the valve stem and adjust to obtain the low cooking
temperature desired, maintaining a stable ame covering
the entire burner (minimum 3/16 inch (5 mm) long
ame).

5. Replace dial and turn to “OFF” position.

Calibration Instructions

1. Use a test instrument with a special disc type
thermocouple or a reliable surface type pyrometer. Note:
a drop of oil on the face of the disc will provide better
contact with the plate.

2 Set all griddle thermostats to 350°F (177°C). In order

to allow the griddle temperature to stabilize, the
thermostats must be allowed to cycle twice before taking
a test reading.

Lighting Instructions And
Pilot Burner Adjustment

Each griddle burner is equipped with a pilot.

For the HI-LO valve operated model, the pilot adjusting valve
pilot burner is located on the manifold to the left of each
griddle valve. Open the pilot valve with a screwdriver and
light the pilot with a match.

3. Check the griddle temperature when the thermostat
just cycles “OFF” by placing the thermocouple rmly on
the griddle surface directly above the sensing bulb of
the thermostat. The reading should be between 335°F
(168°C) and 365°F (185°C). If the reading is outside of
these limits, calibrate as follows:

4. Carefully remove the dial, not disturbing the shaft
position.
