GAS PIPING
Gas piping shall be of such size and so installed as to provide a supply of gas sufficient 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 fittings 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 fixed orifice hoods and is shipped from the factory for use with natural
gas. To convert to propane gas install the orifice 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 orifice
hoods.
4. Remove the natural gas orifice hoods and
install the propane orifice hoods.
5. Slide the burners back over the orifice 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 flame or other sources of ignition shall not be used for
locating gas leaks.
