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 s upply piping mus t be inside 3/ 4” diameter or greater.
3. Use pipe specific sealant for gas piping on all pipe joints. Apply enough sealant to the male threads only.
Sealant must be resistant to the action of liquified petroleum gas (LPG).
4. Ensure all supply piping is clean and free of obstructions, dirt, chips/flakes 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.
Danger: FIRE AND EXPLOSION HAZARD, NEVER use an open flame to check for gas leaks. Fire and explosion
may occur.
Warning: RISK OF INJURY, Installation procedures must be performed by authorized technicians with full
knowledge of all applicable gas-fired appliance codes. Failure can lead to personal injury and property damage.
Important: All pipe joints must be checked for leaks before lighting. Leak checks should be performed
with a soap and water solution.
Installing the appliance
Refer to the nameplate: ensure the fuel type and pressure correspond with the nameplate. Do not
connect the appliance to the wrong fuel type and/or pressure.
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 waterpass prior to the gas piping installation. Re-check the appliance level after installing the gas
pipe.
Each gas appliance is equipped 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 in such a way
for the flow arrow stamped on the body of the regulator points toward the griddle. Wrong installation of
the regulator will result in an extremely hazardous condition.

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 appliance.
Vent hole must point UP.
Important: Ensure the fuel is the gas type. If the available fuel does not match the nameplate
specification, exchange the appliance for the correct type.
Gas pressure setting:
Gas pressure regulator is factory set.
Pilot flame setting:
The pilot adjustments are located between the control valves for each set of burners. The right valve
controls the front pilot; the left valve controls the rear pilot.
Using a small, 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: inside and outside sections of the burner must light
without undue delay. Windy conditions may require a higher flame to allow the pilot to remain ignited.
Adjust burner flame:
Remove all burner control knobs, remove the front panel. Turn on the individual burner. The right knob
controls the front burner; the left knob controls the rear burner.
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
