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:
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 to
identify the code requirement for a shut-off valve.
Shut-off valves, moisture trap and all associated piping must be
supplied by the gas piping installer.
