WARNING:
FIRE HAZARD
This hotplate is supplied with a gas pressure regulator. Failure to properly install the supplied regulator will result in an extremely hazardous condition.
Flow arrow stamped on body of regulator must point toward the hotplate.
Regulator adjusting screw and vent hole must point UP.
INSTALLING THE HOTPLATE
Refer to the nameplate. Verify the fuel type and pressure, which must
match the nameplate specications. Connecting the hotplate to the
wrong fuel type and/or pressure will compromise the safety and/or performance of the appliance.
The hotplate must be placed in its nal operational position and leveled front-to-back and side-to-side, with a spirit level, prior to beginning the gas piping installation. Re-check the level of the unit at
the conclusion of the gas piping installation.
Each gas hotplate is supplied with a separate gas pressure regulator, which must be installed on the manifold pipe protruding from the rear of the hotplate. Ensure that the regulator is installed such that the
ow arrow stamped on the body of the regulator points toward the
hotplate. Failure to properly install the supplied regulator will result in an extremely hazardous condition.
A moisture trap (drip leg) consisting of a tee, 4” nipple pointing down, and cap must be installed upstream of the gas pressure regulator.
A manual gas shut-off valve may be required by local codes and is, in any case, strongly recommended. The shut-off valve must be installed between the gas supply piping and the gas pressure regulator.
It is the responsibility of the gas piping installer toidentify the code requirement for a shut-off valve.
Shut-off valves, moisture trap and all associated piping must besupplied by the gas piping installer.
IMPORTANT:
Verify fuel gas type. If the available fuel does not match
the nameplate specication,
exchange the hotplate for the correct type. DO NOT attempt
to modify a unit in the eld to
accept a different fuel.
IMPORTANT:
Avoid damage to the regulator: if the gas supply piping system is pressure tested at pressures
exceeding 1/2 psig (3.45kPa),
the hotplate must be isolated or disconnected from the gas piping system for the duration of the test.
