GAS PIPING
Gas piping shall be of such size and so installed as to provide a supply of gas suffi cient to meet
the full gas input of the appliance. If the appliance is to be connected to existing piping, it shall
be checked to determine if it has adequate capacity. Joint compound shall be used sparingly and
only on the male threads of the pipe joints. Such compounds shall be resistant to the action of
L.P. gases. WARNING: Any loose dirt or metal particles which are allowed to enter the gas lines
on this appliance will damage the valve and affect its operation. When installing this appliance,
all pipe and fi ttings must be free from all internal loose dirt.
GAS PRESSURE REGULATOR
A convertible pressure regulator is provided with each griddle. It should be connected to the
inlet pipe at the rear of the unit. The gas supply is then connected to it. The supply pressure to
the regulator is not to exceed 1/2 psig. All units are shipped for use with natural gas. M and T
Series Models are shipped set for 5" water column manifold pressure. TS and TSCHS Series
Models are shipped set for 4" water column manifold pressure.
MANUAL SHUT OFF VALVE
A manual shut off valve should be installed upstream from the manifold and within six feet of
the griddle.
CONNECTING GAS SUPPLY LINE
The gas inlet of the griddle is sealed at the factory to prevent entry of dirt. Do not remove this
seal until the actual connection is made to the gas supply line.
PROPANE GAS - CONVERSION
This griddle is equipped with fi xed orifi ce hoods and is shipped from the factory for use with
natural gas. To convert to propane gas install the orifi ce hoods located behind the front panel
as follows:
1. Remove the front panel by removing the
screws located on the front and bottom.
2. Remove the burner mounting screws in
the center of the combustion chamber
access covers.
3. Slide the burners back off the orifi ce
hoods.
4. Remove the natural gas orifi ce hoods and
install the propane orifi ce hoods.
5. Slide the burners back over the orifi ce
hoods and reinstall the burner mounting
screws.
6. Reinstall the front panel.
7. Set the pressure regulator to 10" (25.4cm) water column by removing the slotted or hex
cap from the center of the regulator. Invert the plug and reinstall. The letters "LP" will now
be visible on the plug. Reinstall the cap. An 1/8" pipe plug is located on the manifold for
attaching a pressure gauge.
CHECKING FOR GAS LEAKS
Check entire piping system for leaks. Soap and water solution or other material acceptable for
the purpose, shall be used in locating gas leakage.
Matches, candle fl ame or other sources of ignition shall not be used for locating
gas leaks.
