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:

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).

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.

INSTALLATION (continued)

SET GAS PRESSURE:

Gas pressure regulator is factory set.

SET PILOT FLAME:

The pilot adjustments are located between the control valves for
each set of burners. The right valve controls the front pilot; the
left valve controls the rear pilot.

Using a small, flat-blade screwdriver, turn the screw clockwise to
decrease the flame size, or counter-clockwise to increase the
flame size.

Adjust the pilot flame to 1/4” high. Test for operation: inside and
outside sections of the burner must light without undue delay.
Drafty conditions may require a higher flame to allow the pilot to
remain lit.

ADJUST BURNER FLAME:

Remove all burner control knobs, then remove the front panel.
Turn an individual burner on. The right knob controls the front

burner; the left knob controls the rear burner.
Loosen the locking screw on the shutter.
Turn the shutter to admit more or less air as required. Adjust the

air shutter until the flame is mostly blue in color.
Tighten the locking screw when finished. Replace the front panel

and all knobs before returning the unit to service.

IMPORTANT:

Adjustments must be performed
by a qualified technician only.

IMPORTANT:

This hotplate is shipped from
the factory equipped for either:
natural gas and adjusted for
sea level to 2000 feet elevation;
or, propane (LP) gas and
adjusted for sea level to 5000
feet elevation.

WARNING:

FIRE HAZARD

IF YOU SMELL GAS:

¤ DO NOT try to light

any appliance.
¤ DO NOT touch any

electrical switch
¤ DO NOT use any

telephone in your
building.

In the event a gas odor is
detected, shut down the

shutoff valve and contact
your local gas supplier
from a neighboring loca­tion.

Follow the instructions
received from the gas
supplier immediately
and exactly.

GENERAL OPERATIONAL NOTES

Carefully read the description of the hotplate operation on the
specification sheet.

Do NOT use this appliance if it has been submerged in water.
Call a qualified technician to examine the appliance and to service
or replace any component which has been submerged. Burners
which have been allowed to become wet must be thoroughly dried
before use.

For initial startup, and any time the gas supply has been shut-off, it
may take several minutes to light the pilot while air in the piping and
manifolds is purged.

The burner control knobs must be turned by hand only. Never use
tools to turn the control knob. If the knob will not turn by hand, do
NOT attempt to force or repair it. Contact your Authorized Wells
Service Agency for repairs. Forced or improperly repaired valves
pose the risk of fire and/or explosion.

Make sure burners, pilot burner and grate assembly are properly
installed before attempting to operate.

LIGHTING THE PILOT LIGHT

Before lighting the pilot light, smell all around the appliance area for
gas. Be sure to smell near floor level because some gas is heavier
than air and will settle to the floor.

For initial startup, and any time the gas supply has been shut-off, it
may take several minutes to light the pilot while air in the piping and
manifolds is purged.

The pilot light must be lighted by hand:
Turn both control knobs to the full OFF position.
Be sure the gas shut-off valve is ON and the appliance has had

time for the air to be purged from the lines.
Light the pilot with a long match or fireplace lighter. Use of a

cigarette lighter is NOT recommended.

SHUT DOWN INSTRUCTIONS

Turn all burner knobs to OFF.
Turn all pilots OFF.
Turn the main gas supply OFF.
