INSTALLATION

GAS APPLIANCE CODE COMPLIANCE

The installation of gas piping from the outlet side of the gas meter or
service regulator to the griddle must be performed by a technician

qualied and certied or licensed to install gas-red equipment.
A licensed and qualied technician must perform the initial startup and

adjustment of this appliance.

The installation of this gas-red appliance must conform to local codes,

or in the absence of such codes, with the current edition of
National Fuel Gas Code ANSI Z223.1.
For use in the State of Massachusetts, this appliance must be installed
in compliance with Massachusetts Fuel Gas and Plumbing Code

CMR 248.

The installation of this gas-red appliance must comply withapplicable

portions of NFPA 96 for ventilation. The current edition of NFPA 96

(Standard for the Installation of Equipment for the Removal of Smoke
and Grease Laden Vapors from Commercial Cooking Equipment)
species ventilation requirements to ensure the removal of exhaust

gasses and products of combustion.
IT IS THE RESPONSIBILITY OF THE INSTALLER TO ENSURE

THAT THIS GAS GRIDDLE INSTALLATION CONFORMS TO ALL
APPLICABLE CODES AND ORDINANCES.

The venting of this appliance must not be obstructed, nor may such

venting interfere with the ow of combustion air required for proper

operation of the gas burners.
Additionally:

1. The gas supply line used to connect the griddle to the gas supply

system must be black iron pipe, or other material as approved by

local ordinance for gas piping.

2. Gas supply piping must be inside 3/4” diameter or greater.

3. Use pipe sealant made specically for gas piping on all pipe joints.

Apply sealant sparingly to the male threads only. Sealant must be
resistant to the action of LP gas.

4. Verify that all supply piping is clean and free of obstructions, dirt,

M122 2M-306626 Owners Manual for HDG-Series Griddles

chips and pipe sealant compound prior to installation.

5. All pipe joints must be checked for leaks before lighting. Leak
checks should be performed with a soap and water solution.

NEVER CHECK FOR LEAKS WITH AN OPEN FLAME.

DANGER:

FIRE AND
EXPLOSION
HAZARD

NEVER use an open ame to
check for gas leaks. Fire and

explosion may result.

WARNING:

RISK OF INJURY

Installation procedures
must be performed by a

qualied technician with full
knowledge of all applicable
gas-red appliance

codes. Failure can result
in personal injury and
property damage.

IMPORTANT:

All pipe joints must be

checked for leaks before
lighting. Leak checks should

be performed with a soap and
water solution.

IMPORTANT:

Information on the
construction and installation
of ventilating hoods may be
obtained from the current
edition of NFPA 96

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 griddle 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 griddle.

Vent hole must point UP.

INSTALLING THE GAS GRIDDLE

Refer to the nameplate. Verify the fuel type and pressure, which must

match the nameplate specications. Connecting the hotplate to the

wrong fuel type and/or pressure will compromise the safety and/or
performance of the appliance.

BE SURE TO MAINTAIN REQUIRED CLEARANCES TO
COMBUSTIBLE SURFACES.

The griddle must be placed in its nal 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 griddle is supplied with a separate gas pressure regulator,

which must be installed on the manifold pipe protruding from the rear
of the griddle. Ensure that the regulator is installed such that the

ow arrow stamped on the body of the regulator points toward the

griddle. 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.

IMPORTANT:

Verify fuel gas type. If the
available fuel does not match

the nameplate specication,

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).

SET PILOT FLAME:

Remove all burner control knobs, then remove the front panel.

The pilot adjustments are near the control valve for each set of

burners.

Using a small, at-blade screwdriver, turn the screw clockwise to

decrease the ame size, or counter-clockwise to increase the
ame size.

Adjust the pilot ame to 1/4” high. Test for operation: all sections

of the burner must light without undue delay. Drafty conditions

may require a higher ame to allow the pilot to remain lit.

Replace the front panel and all knobs before returning the unit to

service.

ADJUST BURNER FLAME:

Remove all burner control knobs, then remove the front panel.

Turn an individual burner on.

Loosen the locking screw on the shutter.

Turn the shutter to admit more or less air as required. Adjust the

air shutter until the ame is mostly blue in color.

Tighten the locking screw when nished. Replace the front panel

and all knobs before returning the unit to service.

IMPORTANT:

Adjustments must be performed

by a qualied technician only.

IMPORTANT:

The griddle is shipped from
the factory equipped for natural
gas and adjusted for sea
level to 2000 feet elevation.
For conversion to LP / Propane,
or for operation above 2000
feet elevation, contact your
Authorized Wells Service
Agency.

OPERATION

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 unit at
the main gas 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 griddle operation on the

specication sheet.

Do NOT use this appliance if it has been submerged in water. Call a

qualied 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 re and/or explosion.
Make sure burners, pilot burner and grease tray are properly installed

before attempting to operate.

LIGHTING THE PILOT FLAME

Before lighting the pilot light, smell all around the appliance area for

gas. Be sure to smell near oor level because some gas is heavier
than air and will settle to the oor.

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 all control knobs to the full OFF position.

The pilot is located adjacent to one leg of the burner, and is

accessible through the front panel opening.

Be sure the gas shut-off valve is ON and the appliance has had

time for the air to be purged from the lines. Attempt to light the pilot

every 15 seconds after the gas valve is turned on.

Light the pilot with a long match or replace lighter.

DO NOT use a cigarette lighter.

M122 2M-306626 Owners Manual for HDG-Series Griddles

SHUT DOWN INSTRUCTIONS

Turn all burner knobs to OFF.

Turn all pilots OFF.
Turn the main gas supply OFF.
