INSTALLATION (continued)
DANGER:
FIRE AND
EXPLOSION HAZARD
NEVER use an open flame to
check for gas leaks. Fire and
explosion may result.
IMPORTANT:
All pipe joints must be checked
for leaks before lighting. Leak
checks should be performed
with a soap and water
solution.
WARNING
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.
IMPORTANT:
Verify fuel gas type. If the
available fuel does not match
the nameplate specification,
exchange the hotplate for the
correct type. DO NOT attempt
to modify a unit in the field 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.
INSTALLING THE HOTPLATE
Refer to the nameplate. Verify the fuel type and pressure, which must
match the nameplate specifications. 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 final 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
flow 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.
