Star ULTRA-MAX 802H Instructions D'installation Et D'opération page 6

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 hotplate. 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. It is shipped set for 5" water column manifold pressure
for use with natural gas.
MANUAL SHUT OFF VALVE
A manual shut off valve should be installed upstream from the manifold and within six feet of
the hotplate.
CONNECTING GAS SUPPLY LINE
The gas inlet of the hotplate 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 hotplate is equipped with fixed orifice hoods and is shipped from the factory for use with
natural gas. To convert to propane gas, install the burner orifice hoods, located on the manifold,
as follows:
1. Remove grates and burners.
2. Remove the burner orifice hoods and install the orifice hoods supplied.
3. Replace the burners and grates. Be sure venturi opening is positioned on valve orifice.
4. Set manifold pressure to (10) inch water column. A 1/8" pipe plug on the burner manifold
can be removed for attaching a pressure gauge. Remove the slotted, or hex-threaded plug
from the pressure regulator. Invert the plug and
now be visible on the plug. The regulator is now set for 10" (25.4 cm) water
column. Attach the conversion label, supplied with the unit, close to the nameplate
on the top side of the front panel. Pilot flame may need to be adjusted for LP gas.
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.
