UNPACKING
IMMEDIATELY INSPECT FOR SHIPPING DAMAGE
Immediately after unpacking the steamer, check for possible shipping damage. If the steamer is found to be damaged,
save the packaging material and contact the carrier within 15 days of delivery.
Prior to installation, verify that the type of gas supply (natural or propane) and electrical service agree with the
and equipment requirements do not agree, contact your dealer immediately.

INSTALLATION
I C S
Installation must conform with local codes, or in the absence of local codes, with the National Fuel Gas Code,
ANSI Z223.1/NFPA 54, or the Natural Gas and Propane Installation Code, CSA B149.1, as applicable.
1. The appliance and its individual shut off valve must be disconnected from the gas supply piping system during
any pressure testing of that system at pressures in excess of 1/2 psi (3.5 kPa).
during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psi (3.5 kPa).
Electrical grounding must be provided in accordance with local codes, or in the absence of local codes, with the
National Electrical Code, ANSI/NFPA 70, or the Canadian Electrical Code, CSA C22.2, as applicable.
The electrical diagram is located on the inside of the console control cover
EXHAUST FANS AND CANOPIES: Canopies are set over ranges, ovens and kettles for ventilation purposes.
It is recommended that a canopy extend 6” past appliance and be located 7.5 feet from the floor. Filters should
be installed at an angle of 45 degrees or more with the horizontal. This position prevents dripping of grease and
facilitates collecting the run-off grease in a drip pan, usually installed with the filter. A strong exhaust fan tends to
create a vacuum in the room and may interfere with burner performance or may extinguish pilot flames. Makeup
air openings approximately equal to the fan area will relieve such vacuum. In case of unsatisfactory performance
on any appliance, check operation with exhaust fan in the “OFF” position.
WALL EXHAUST FAN: The exhaust fan should be installed at least 2 feet above the vent opening at the top of the unit.
CLEARANCES: Adequate clearance must be provided in aisle and at the side and back. Adequate clearances for
air openings into the combustion chamber must be provided, as well as for serviceability.
SIDES 6 INCHES
BACK 2 INCHES AT FLUE BOX
Provisions for an adequate air supply must also be provided. Do not obstruct the lower front or right side of the unit,
as combustion air enters through these areas. The bottom of the control area must also remain unobstructed.

WARNING
All connections must be checked for leaks, after the unit has been put in operation.
NOTICE
If applicable, the vent line from the gas appliance pressure regulator shall be installed to the outdoors in accordance
with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1/NFPA 54, or the
Natural Gas and Propane Installation Code CSA B149.1, as applicable.

1. Uncrate carefully. Report any hidden freight damage to the freight company immediately.
2. Set the unit in place. Be certain to maintain minimum clearances as stated above.
3. To level the unit use a spirit level in all directions on the top of the kettle (lid up).
2. Units with casters - loosen the locking nuts, turn casters in or out as required and tighten locking nuts.
4. Be certain to leave adequate clearances for cleaning, maintenance and service.
5. The pressure relief valve is located at the left rear of the unit. This area should be kept clear and should not be in an
the atmosphere.
6. Check the pressure gauge on the front panel before operating. If the pressure gauge does not indicate green vacuum
zone (below 0 psi), see “Re-establishing Vacuum” section under SERVICE, after completing installation instructions.
The serial plate on the lower right side of the unit indicates the type of gas your unit is equipped to burn. Do NOT connect to any
other gas type.
A 1” NPT line is provided at the rear for the connection. Each unit is equipped with an internal pressure regulator which is set for
pressure.
An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of gas required for satisfactory
Contact your gas company for correct supply line sizes.
Purge the supply line to clean out any dust, dirt, or other foreign matter before connecting the line to the unit. It is recommended
for use with LP gas on all threaded connections. Test pipe connections thoroughly for gas leaks.

WARNING
For an appliance equipped with casters, the installation shall be made with a connector that complies with the
standard for connectors for moveable gas appliances, ANSI Z21.69-CSA 6.16 and a quick-disconnect device that
complies with the standard for quick-disconnect devices for use with gas fuel, ANSI Z21.41-CSA 6.9; adequate
means must be provided to limit the movement of the appliance without depending on the connector and the quick
disconnect device or its associated piping to limit the appliance movement; the location where the restraining
means may be attached to the appliance is on bottom of unit directly below relief valve.

ELECTRICAL GROUNDING INSTRUCTIONS
This appliance is equipped with a three-prong (grounding) plug for your protection against shock hazard
and should be plugged directly into a properly grounded three-prong receptacle. Do not cut or remove the
grounding prong from this plug. (120V units only).

120V, three-prong grounded receptacle. A separate 15 amp supply is needed for each unit.
2. 208/240 VAC - 60 Hz - Single and Three Phase
Units with this electrical rating are factory equipped with a transformer. To connect supply wires remove cover from
transformer box at right rear of unit. Route supply wires and ground wire through the hole in the cover with a strain relief
wire to ground lug. Replace cover. Three-phase units are wired as above, using only two supply wires. The third supply
wire is not connected and must be properly terminated.
3. 220 VAC - 50 Hz - Single Phase
Units equipped with this voltage rating should be wired exactly as in (Step 2) above.

A. START-UP
1. Turn thermostat to “OFF” position and power switch to “OFF” position.
2. Open control panel access door located on right side at bottom.
3. Turn dial on combination control to “ON” position by rotating control knob counterclockwise. (NOTE: Any gas service
valves exterior to the unit should be open.)
5. Set “COOK TEMP” to desired setting. The red “COOKING” pilot will be on until desired setting has been reached.
6. At this time the spark igniter will begin sparking at the pilot until the pilot is ignited, or for ninety seconds (an audible
clicking sound will be evident).

1. Place power on switch and thermostat to “OFF” position.
2. COMPLETE
1. Place power on switch and thermostat to “OFF” position.
2. Turn dial on combination control from “ON” position to “OFF” position.
3. Turn any main gas service valves supplying gas to “OFF” position.
C. RE-LIGHTING
1. Turn power switch to “ON” position.
It should be noted that the pilot and electronic ignition do not cycle with the thermostat. A standing pilot is automatically
established and monitored each time the power switch is turned ON. If the pilot is ever extinguished by a momentary external
interruption, the spark igniter will automatically relight it without disturbing the cooking cycle, unless lockout occurs.
In the event the spark igniter module fails the unit may still be operated by carefully following these instructions.
1. Turn thermostat to OFF position; completely counterclockwise.
2. Turn power switch to OFF position.
3. WAIT A MINIMUM OF 5 MINUTES BEFORE PROCEEDING.
4. Turn dial on combination control to ON position (if not already on).
5. Turn power switch to ON position.
8. The pilot will now stay ignited as long as the power switch remains ON. If power switch is turned OFF, repeat the
above instructions. It is intended that the unit be operated in this manner only in emergency situations and only while

Clean as required or on a daily basis. See “Cleaning” section under MAINTENANCE.
Appliances equipped with casters have been installed with a restraint to limit their movement to prevent damage to the
gas supply connecting system. If disconnection of this restraint is necessary to move the appliance for cleaning, etc.,
reconnect it when the appliance is moved to its originally installed position.
Turning on the power switch initiates a pilot lighting sequence. The spark igniter will begin sparking. The spark igniter will
spark until the pilot is ignited. After ninety seconds lockout will occur. Lockout shuts down all pilot (and main burner) gas
