CONNECTING GAS SUPPLY LINE
The gas inlet of the griddle is sealed at the factory to prevent the entry of dirt and debris. Do not
remove this seal until the actual connection is made to the gas supply line.
CHECKING FOR GAS LEAKS
Soap and water solution or other material acceptable for the purpose should be used in locating
gas leakage. Matches, candle flame, or other sources of ignition should not under any circumstances
be used for this purpose. Check the entire piping system for leaks immediately after connection.
LIGHTING INSTRUCTIONS
The griddles are equipped with standing pilots and should be lit immediately after the gas is turned
on. Pilot flames can be lit and observed through the front panel view ports, but the best access for
lighting the pilot is from the bottom of the unit, behind the center wall. When griddle is first lit, it will
smoke until the preservation oils and impurities are burned off. Use the following procedure to light
all pilots.
i. Turn off the main valve to the unit and wait 5 minutes to clear gas.
ii. Turn off all knobs and pilot valves.
iii. Turn on the main valve and light all pilots.
iv. Turn the burner knobs to desired setting.
v. To turn burners off, turn knobs off.
PILOT LIGHT REGULATION
Adjust pilot light flames as small as possible, while still being high enough to light burner immediately
when the burner valve is turned on high. The flame should be solid blue with no flickering or yellow
tipping.
BURNER ADJUSTMENT
i. Remove the front panel.
ii. Set the thermostat or control setting of one burner to 450° F (232° C).
iii. Loosen the shutter retaining screw, and close the air shutter on the front of the burner to give a soft
blue flame with luminous yellow tips and open to a point where the yellow tips disappear and a hard
blue flame with darker blue inner cone is obtained. Tighten the shutter screw.
iv. Repeat for all burners.
v. Return thermostat to off position and return power switch[es] to “OFF” and proceed to replace the
front panel.
