2. GENERAL INSTALLATION INSTRUCTIONS:
Ensure gas supply and gas type, as shown on unit nameplate agree.
Unit installation must conform with the National Fuel Gas Code, ANSI Z223.1-1996, the National Gas
Installation Code, CAN/CGA-B149.1, or the Propane Installation Code, CAN/CGA-B149.2 as applicable
and in accordance with local codes.
Screw legs into the permanently fastened nutson the four corners of the unit and tighten by hand. Level the
unit by turning the adjustment screw at the bottom of each leg. Do not slide unit with legs mounted, lift if
necessary to move unit.
Pipe gas supply to unit.
Pipe threading compound must be resistant to the action of liquefied petroleum gases.
These units are suitable for installation on noncombustible surfaces only.
Caution: DO NOT use an open flame to check for leaks. Check all gas piping for leaks
!
with a soap and water solution before operating unit.
GGT Griddles are furnished with either a pilot safety valve or a standing pilot (not available in the
European Community). Please follow the instructions for your unit.
Pilot Safety Valve Lighting Instructions
1Turn on maingas supply to unit, on-off valve locatedbehind the unit (not suppliedwith unit).
2Turn the burner control knobs to "OFF" position. Open the front panel and wait at least 5 minutes to
allow any gas which may have accumulated in the firebox compartment to escape.
3Depress red button on the pilot safety valve and light through observation hole in firebox. Keep red
button on pilot safety depressed for at least 1 minute after pilot has lit. If pilot does not light, repeat
this step.
4To adjust the pilot flame, rotate knob next to the red button. Turning the knob clockwise increases
the pilot flame. A properly sized pilot should be 1/2" to 3/4" long (12/19 mm).
Standing Pilot Lighting Instructions (Not Available in theEuropean Community )
The pilot lights on the griddles have been set at the factory. A screwdriver maybe required for the
first lighting to adjust the flame for your elevation.
1Turn off the manual shut off valve and wait 5 minutesto clear the gas.
2Turn all knobsto the "OFF" position.
3Remove the grease drawer and front panel for easy access.
4Turn the manualshut off valve on.
5Hold an ignition source (match) at the pilot tube. When the flame is established, remove the ignition
source.

6Turn the burner knobs to "HI". If the burner does not ignite, promptly open the pilot valve more. If the
pilot flame appears larger than necessary, turn it down and reset burner ignition. The pilot flame
should be as small as possible but large enough to guarantee reliable ignition of the burners when
the knobs are turned to "HI".
7Replace the front panel and grease drawer.
Lighting Main Burner:
Since the burner is lit from constantly burning pilot, turn knob to “HI” to put the unit in operation; then
adjust to any desired position between “LO” and “HI”.
Main Burner Air Supply:
For efficient burner operation, a proper balance of gas volume and primary air supply must be
maintained which will result in complete combustion. Insufficient air supply results in a yellow
streaming flame. Primary air supply is controlled by an air shutteron the burner.
Loosen the screws on the front of the burner, and adjust the air shutter to eliminate the yellow on
the burner flame. Lock the air shutter in place by tighteningthe screws.
European Community:
If adjustment becomes necessary in the field, it should be done by a factory authorized and trained
technician who should seal the screw after the adjustment to safeguard against unauthorized
tampering by the end user.
All burners are lit from constantly burning pilots, turning the control valve as desired is all that is
required to put the unit in service.
Do not permit fans to blow directly on the unit. Wherever possible, avoid open windows next to the
unit’s sides or back. Avoid wall type fans which create air cross-currents within the room.
It is also necessary that sufficient air should be allowed to enter the room to compensate for the
amount of air removed by any ventilating system. Otherwise, a subnormal atmosphere will occur,
adversely affecting operation and causing undesirable working conditions.
A properly designed and installed hood will act as the heart of the ventilating system for the room or
area in which the unit is installed, and will leave the unit independent of changing draft conditions.
All valves must be checked and lubricated periodically.Consult the authorized service
representative in your area.
Season Griddle:
Heat to low temperature (300 - 350 F/150-180C) and pour on a small amount of cooking oil, about
one ounce (30cc) per square foot of surface. Spread the oil over the entire griddle surface with a
cloth to create a thin film. Wipe off any excess oilwith a cloth.Repeat this procedure 2 to3 times until
the griddle has a slick, mirror-like surface.
Operation:
Turn the burners on about 15-20 minutes before cooking for preheating. Set the knobs to the
desired flame height or temperature. Each thermostat will control the burner to bring that area of the
plate up to the set temperature. If different temperature settings are to be used, adjoining areas
should be set at progressively higher temperatures using the lowest temperatures on the outside
burners. A uniform and systematic approach to the loading of the griddle will produce the most
consistent product results.

6. CLEANING / MAINTENANCE
Initial Cleaning:
Prior to operating your new griddle, thoroughly wash the griddle surface and the exterior with a mild
detergent or soap solution. Do not use abrasive cleaners since thismight damage the cabinetfinish.
If the stainless steel surfaces become discolored, scrub by rubbing only in the direction of the
finished grain.
Cleaning:
1Always turn unit off and allow it to cool completely before cleaning. Clean thoroughly before first
use.
2After each use, clean the griddle with wire brush or flexible spatula.
3Once a day, thoroughly clean splash back, sides and front. Remove the grease drawer, empty it and
wash it out.
4Once a week, clean the griddle surface thoroughly. If necessary, use a griddle stone, wire brush or
steel wool on the surface. Rub with the grain of the metal while the griddle is still warm. A detergent
may be used on the plate surface to help clean it; but, care must be taken to be sure the detergent is
thoroughly removed. After removal of the detergent, the surface of the plate should then be covered
with a thin film of oil to prevent rusting. Clean stainless surfaces with a damp cloth and polish with a
soft dry cloth. To remove discoloration, use a non-abrasive cleaner. After each "weekly" cleaning,
the griddle must be seasoned again. If the griddle usage is very high, the "weekly" cleaning
procedures may be done more often than once a week.
Parts protected by the manufacturer or his agent are not to be adjusted by the installer
unless the installer is an authorized service agent.
!
The conversion should be done before connecting the unit to the gas supply.
1Remove the knobs and front panel.
2Remove the supply tubes that go between the valves and the orifice fittings.
3Remove the orifice fittings from the firebox. Change the orifices to the size recommended for
propane (L.P.).
4Replace the orifice fittings into the firebox.
5Replace the supply tubes between the valves and the orifice fittings.
6Replace the front panel, grease drawer and knobs.
7Reverse plug in pressure regulator.The marking on the plugfacing out should match gas supply.
8Continue with the installation.
