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.
