GAS APPLIANCE CODE COMPLIANCE
The installation of gas piping from the outlet side of the gas meter or
service regulator to the charbroiler must be performed by a technician
qualified and certified or licensed to install gas-fired equipment.
A licensed and qualified technician must perform the initial startup and
adjustment of this appliance.
The installation of this gas-fired appliance must conform to local codes,
or in the absence of such codes, with the current edition of
National Fuel Gas Code ANSI Z223.1.
The installation of this gas-fired appliance must comply with
applicable portions of NFPA 96 for ventilation. The current edition of
NFPA 96 (Standard for the Installation of Equipment for the Removal
of Smoke and Grease Laden Vapors from Commercial Cooking
Equipment) specifies ventilation requirements to ensure the removal
of exhaust gasses and products of combustion.
IT IS THE RESPONSIBILITY OF THE INSTALLER TO ENSURE
THAT THIS GAS GRIDDLE INSTALLATION CONFORMS TO ALL
APPLICABLE CODES AND ORDINANCES.
The venting of this appliance must not be obstructed, nor may such
venting interfere with the flow of combustion air required for proper
operation of the gas burners.
Additionally:
1. The gas supply line used to connect the appliance to the gas
supply system must be black iron pipe, or other material as
approved by local ordinance for gas piping.
2. Gas supply piping must be 3/4” inside diameter or greater.
3. Use pipe sealant made specifically for gas piping on all pipe joints.

Sealant must be resistant to the action of LP gas.
4. Verify that all supply piping is clean and free of obstructions, dirt,
chips and pipe sealant compound prior to installation.
5. All pipe joints must be checked for leaks before lighting. Leak
checks should be performed with a soap and water solution.
NEVER CHECK FOR LEAKS WITH AN OPEN FLAME.

INSTALLING THE GAS GRIDDLE
Refer to the nameplate. Verify the fuel type and pressure, which must
match the nameplate specifications. Connecting the hotplate to the
wrong fuel type and/or pressure will compromise the safety and/or
performance of the appliance.
BE SURE TO MAINTAIN REQUIRED CLEARANCES TO
COMBUSTIBLE SURFACES.
The appliance must be placed in its final operational position and
leveled front-to-back and side-to-side, with a spirit level, prior to
beginning the gas piping installation. Re-check the level of the unit
at the conclusion of the gas piping installation.
Each gas appliance is supplied with a separate gas pressure
regulator, which must be installed on the manifold pipe protruding
from the rear of the griddle. Ensure that the regulator is installed
such that the flow arrow stamped on the body of the regulator points
toward the griddle. Failure to properly install the supplied regulator
will result in an extremely hazardous condition.
A moisture trap (drip leg) consisting of a tee, 4” nipple pointing down,
and cap must be installed upstream of the gas pressure regulator.
A manual gas shut-off valve may be required by local codes and is,
in any case, strongly recommended. The shut-off valve must be
installed between the gas supply piping and the gas pressure
regulator.
It is the responsibility of the gas piping installer to identify the code
requirement for a shut-off valve.
Shut-off valves, moisture trap and all associated piping must be
supplied by the gas piping installer.
DANGER:
FIRE AND
EXPLOSION
HAZARD
NEVER use an open flame to
check for gas leaks. Fire and
explosion may result.
IMPORTANT:
All pipe joints must be checked
for leaks before lighting. Leak
checks should be performed
with a soap and water solution.
WARNING:
FIRE HAZARD
This appliance is supplied with
a gas pressure regulator.
Failure to properly install the
supplied regulator will result in
an extremely hazardous
condition.
Flow arrow stamped on body
of regulator must point toward
the griddle.
Vent hole must point UP.
IMPORTANT:
Verify fuel gas type. If the
available fuel does not match
the nameplate specification,
exchange the appliance for the
correct type.
IMPORTANT:
The appliance and its
individual manual shutoff valve
must be disconnected from
supply system piping during
any pressure testing of that
system at pressures in excess
of 1/2 p.s.i. (3.5 kPa).
Also, the appliance must be
isolated from the gas supply
piping system by closing its
individual manual shutoff valve
during any pressure testing of
the gas supply piping at test
pressures equal to or less than
1/2 p.s.i. (3.5 kPa).

The pilot adjustments are near the control valve for each set of
burners.
Using asmall, flat-blade screwdriver, turn the screw clockwise to
decrease the flame size, or counter-clockwise to increase the
flame size.
Adjust the pilot flame to 1/4” high. Test for operation: all sections
of the burner must light without undue delay. Drafty conditions
mayrequire ahigher flame to allow the pilot to remain lit.
Replace the grates, front panel and all knobs before returning the
unit to service.
ADJUST BURNER FLAME:
Remove all burner control knobs, then remove the front panel.
Remove grates and radiants.
Turn an individual burner on.
Loosen the locking screw on the shutter.
Turn the shutter to admit more or less air as required. Adjust the
air shutter until the flame is mostly blue in color.
Tighten the locking screw when finished. Replace tall grates and
radiants, the front panel and all knobs before returning the unit to
service.
INSTALLATION (continued)
IMPORTANT:
Adjustments must be performed
by aqualified technician only.
IMPORTANT:
The appliance is shipped from
the factory equipped for natural
gas and adjusted for sea level

WARNING:
FIRE HAZARD
IF YOU SMELL GAS:
¤ DO NOT try to light
any appliance.
¤ DO NOT touch any
electrical switch
¤ DO NOT use any
telephone in your
building.
In the event agas odor is
detected, shut down the
unit at the main gas shut-
off valve and contact your
local gas supplier from a
neighboring location.
Follow the instructions
received from the gas
supplier immediately
and exactly.
GENERAL OPERATIONAL NOTES
Carefully read the description of the charbroiler operation on the
specification sheet.
Do NOT use this appliance if it has been submerged in water.
Call aqualified technician to examine the appliance and to service
or replace any component which has been submerged. Burners
which have been allowed to become wet must be thoroughly dried
before use.
For initial startup, and any time the gas supply has been shut-off, it
maytake several minutes to light the pilot while air in the piping and
manifolds is purged.
The burner control knobs must be turned by hand only. Never use
tools to turn the control knob. If the knob will not turn by hand, DO
NOT attempt to force or repair it. Contact your Authorized ICB
Service Agency for repairs. Forced or improperly repaired valves
pose the risk of fire and/or explosion.
Make sure burners, pilot burner and drip tray are properly installed
before attempting to operate.
LIGHTING THE PILOT FLAME
Before lighting the pilot light, smell all around the appliance area for
gas. Be sure to smell near floor level because some gas is heavier
than air and will settle to the floor.
For initial startup, and any time the gas supply has been shut-off, it
maytake several minutes to light the pilot while air in the piping and
manifolds is purged.
The pilot light must be lighted by hand:
Remove grates. Turn all control knobs to the full OFF position.
The pilot is located adjacent to the burner, and is accessible from
the top of the unit.
Be sure the gas shut-off valve is ON and the appliance has had
time for the air to be purged from the lines. Attempt to light the
pilot every 15 seconds after the gas valve is turned on.
Light the pilot with along match or fireplace lighter.
DO NOT use acigarette lighter.
Reinstall grates
SHUT DOWN INSTRUCTIONS
Turn all burner knobs to OFF.
Turn all pilots OFF.
Turn the main gas supply OFF.
