ENGLISH

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.

Vent hole must point UP.

IMPORTANT:

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.

Verify fuel gas type. If the available fuel does not match the nameplate specification, exchange the hotplate for the correct type.

IMPORTANT:

The appliance and its individual manual shutoff valve must be disconnected from supply system piping during any pressure testing of that system at pressures in excess of 1/2 p.s.i. (3.5 kPa).

Also, the appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping at test pressures equal to or less than 1/2 p.s.i. (3.5 kPa).
