EXHAUST CANOPY
It is essential that facilities be provided over the griddle to carry off fumes and gases. However, the
unit should not be directly connected to a flue or stack.
LEVELING UNIT
This griddle is supplied with (4) feet which must be screwed into the legs attached to the body. Level
unit by adjusting the (4) feet which have an adjustment of -/4" (4.75mm) for accurate and perfect
lineup with other units.
DO NOT INSTALL WITHOUT ATTACHING FEET - DO NOT REMOVE FEET.
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 LP 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 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 line is then connected to it. It is shipped set for 6" (5.4cm)
water column manifold pressure for use with natural gas.
MANUAL SHUT-OFF VALVE
A manual shut-off valve should be installed upstream from the union and within 6 feet (.89m) of this
appliance.
GAS CONVERSION
This griddle is equipped with fixed orifice hoods and is shipped from the factory for use on either
natural or LP gas. To convert to propane gas, install the burner orifice hoods, located in the grease
drawer, (NAT orfices are not included) as follows:
. Remove front panel by removing screws located on the front and the bottom.
2. Remove the burner(s) from the orifice hood(s). This is accomplished by removing the burner
mounting screw(s) and sliding the burner(s) off the hood(s).
3. Remove natural gas orifice hood(s) and install the propane hood(s) furnished.
4. Reinstall burner(s).
Note: MD and TD series units use a #47 drill orifice for natural gas and a #55 drill orifice
for propane. TCHSD and TSPD series units (w/safety pilots) use a #41 drill orifice for
natural gas and a #52 drill orifice for propane gas.
5. Reinstall front panel.
6. Remove the slotted, or hex-threaded, plug from the pressure regulator. Invert the plug and re-
install. The letters "LP or NAT" should now be visible on the plug. LP units the regulator is now
set for 0" (5.4cm) water column, and NAT units the regulator is now set for 6" (5.4cm) water
column.
7. For LP Gas, set manifold pressure to 0" (5.4cm) water column. A /8" pipe plug on the supply
pipe can be removed for attaching a pressure gauge.
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.
CHECKING FOR GAS 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 this purpose.
Check entire piping system for leaks.
