INTRODUCTION
Important Information:
Safe and satisfactory operation of your equipment depends on proper installation. Installation must
conform with local codes, or in the absence of local codes, the National Fuel Gas Code, (ANSI Z-223.1
Latest Edition). In Canada installation should conform to installation codes for gas burning appliances
and equipment standard (CAN1-B149.1 Natural Gas) or (CAN1-B149.2 Propane Gas).
The installation must conform with local codes, or in the absence of local codes, to the national fuel gas
code, ANSI Z223.1 (or latest addenda). The Appliance and its individual shut off valve must be
disconnected from the gas supply piping system during any pressure testing of that system in excess of
1/2 PSI (3.45Kpa).
The appliance must be isolated from the gas supply piping system by closing its individual manual shut
off valve during any pressure testing of the gas supply piping system at test pressures equal to or less
than 1/2 PSI (3.45Kpa). The gas supply line must be at least the same size as the gas inlet of the
appliance.
Electrical wiring from the Electric Meter, main control box or service outlet to appliance must be
electrically grounded in accordance with local codes or, in the absence of local codes, the National
Electric Code (ANSI/NFPA 70 Current). In Canada wiring should conform with Canadian Electrical Code
(CSA-C22.1).
Shipping Damage Claim Procedure:
The equipment is crafted and inspected carefully by skilled personnel before leaving the factory. The
transportation company assumes full responsibility for safe delivery upon acceptance of this equipment.
If shipment arrives damaged:
Visible loss or damage:
Note the damage or loss on freight bill or express delivery and signed by the person making the delivery.
File claim for damages immediately:
Regardless of the extent of damages.
Concealed loss or damage:
If damage is noticed after unpacking, notify the transportation company immediately and file a
"Concealed Damage" claim with them. This should be done within fifteen (15) days from the date
delivered. Retain container for inspection.
Service:
Installation of the equipment should be performed by qualified, certified, licensed and/or authorized
personnel who are familiar with and experienced in state/local installation codes.
Operation of the equipment should be performed by qualified and authorized personnel who have read
this manual and are familiar with the functions of the equipment.
Service of the equipment should be performed by qualified personnel who are knowledgeable with
Market Forge cooking equipment.

3
Air Supply and Ventilation:
Provisions shall be incorporated in the design of the kitchen, to ensure adequate supply of fresh air and
adequate clearance for air openings into the combustion chamber, for proper combustion, and
ventilation. For proper operation of the appliance, do not obstruct the flow of combustion and
ventilation air.
The area in front of, around and above the appliance must be kept clear to avoid any obstruction of the
flow of combustion and ventilation air. Adequate clearance must be maintained at all times in front and
at the sides of the appliances for servicing and proper operation.
Means must be provided for any commercial, heavy-duty cooking appliance to exhaust combustion
waste products to the outside of the building. Usual practice is to place the unit under an exhaust hood.
Filters and drip troughs should be part of any industrial hood. Consult local codes before constructing
and installing a hood.
Strong exhaust fans in this hood or in the overall air conditioning system can produce a slight vacuum in
the room and/or cause air drafts, either of which can interfere with pilot or burner performance and can
also be hard to diagnose. Air movement should be checked during installation; if pilot or burner outage
problems persist, make-up air openings or baffles may have to be provided in the room.

INSTALLATION
READ BEFORE INSTALLING
Clearance:
When installing against combustible surfaces; rear - 4” (102mm) and sides - 15” (381mm) clearance is
required. When installing ovens against non-combustible surfaces (rear or side walls) 0” clearance is
required.
The area around the appliance must be kept free and clear of combustibles such as solvents, cleaning
liquid, broom, rags, etc. Proper clearances must be provided at the front of the appliance for servicing
and proper operation.
Leveling:
A carpenter’s spirit level should be placed on the oven’s center baking rack and the unit leveled both
front-to-back and side-to-side. If it is not level, cakes, casseroles, and any other liquid or semi-liquid
batter will not bake evenly, burner combustion may be erratic, and the unit will not function efficiently.
If the floor is relatively smooth and level, the unit may be further leveled with adjustment in the foot of
the leg. Units with casters must be leveled with shims. A unit will probably not return to the same
position after being moved, requiring re-leveling after each and every move.
Rating Plate:
The rating plate is located in front of the range below the oven section. Information on this plate
includes the model, and serial number, BTU / hour input of the burners, operating gas pressure in inches
WC, and whether the appliance is orificed for Natural or Propane gas. Pilot lighting instructions are also
located in the same area.
UNIT MUST BE CONNECTED ONLY TO THE TYPE OF GAS IDENTIFIED ON THE RATING PLATE!
Electrical Connection:
Oven requires a 120 volt supply to operate the ignition system and blower. The supply cord provided
along with the appliance is equipped with a three prong (grounding) plug for protection against shock
hazard. The electrical service in the building must be equipped with a properly grounded three prong
receptacle, in accordance with local codes, or in the absence of local codes, with the national electrical
code, ANSI/NFPA 70-1987, in Canada, conform with Canadian electrical codes, CSA-C22.1.
Do not cut or remove the grounding prong from this plug. Wiring diagram is located on the backside of
the appliance.
Disconnect power supply before cleaning or servicing.
NOTE: This appliance is not capable of being operated in the event of power failure. No attempt should
be made to operate this appliance during power failure.
Gas Connection:
The gas supply (service) line must be the same size or greater than the inlet line of appliance. Oven uses
a 3/4” NPT inlet. Sealant on all pipe joints must be resistive to LP gas.

Manual Shut-Off Valve:
This installer-supplied valve must be installed in the gas service line ahead of the appliance and
regulator in the gas stream and in a position accessible in the event of an emergency.
Pressure Regulator:
Gas pressure regulator provided with the equipment must be installed when the appliance is connected
to gas supply.
All commercial cooking equipment must have a pressure regulator on the incoming service line for safe
and efficient operation, since service pressure may fluctuate with local demand. The pressure regulator
comes with the oven. Failure to install the pressure regulator will void the equipment warranty!
The regulators supplied with MARKET FORGE INDUSTRIES, INC. Ovens, have 3/4” inlet /outlet openings
and are adjusted at the factory for 5” WC (Natural gas) or 10” WC (Propane gas) depending on
customer’s ordering instructions.
Prior to connecting the regulator, check the incoming line pressure, as these regulators can only
withstand a maximum pressure of ½ PSI (14”WC). If the line pressure is beyond this limit, a step-down
regulator will be required. The arrow shown on the bottom of the regulator body shows gas flow
direction; it should point downstream to the appliance. The red air vent cap on the top regulator is part
of the regulator and should not be removed.
Any adjustments to regulators must be made only by qualified service personnel with the proper
equipment.
Connections:
Please check installer-supplied intake pipes visually and /or blow them out with compressed air to clear
any dirt particles, threading chips, or other foreign matter before installing a service line. When gas
pressure is applied these particles can clog orifices. All connections must be sealed with a joint
compound suitable for LP gas, and all connections must be tested with a soapy water solution before
lighting any pilots!
Flexible Coupling, Connectors and Casters:
For an appliance equipped with casters the installation shall be made with a connector that complies
with the Standard for Connectors for Movable Gas Appliances, ANSI Z21.69 or Connectors for Moveable
Gas Appliances, CAN/CGA-6.16, and a quick –disconnect device that complies with the standard for
Quick Disconnect Devices for Use with Gas Fuel, ANSI Z21.41, or Quick Disconnect Devices for Use with
Gas Fuel, CANI-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. Restraining devices may be attached to the back frame/panel of the unit.
If legs or casters are not used, the unit must extend 2” beyond the front edge of a noncombustible curb
or platform. Broilers are for installation in non-combustible locations only.
Before lighting, check all joints in the gas supply line for leaks.
DO NOT USE AN OPEN FLAME TO CHECK FOR LEAKS!
Putting an open flame beside a new gas connection is extremely dangerous.

7
DO NOT USE APPLIANCE DURING PROLONGED POWER FAILURE AS THE VENT HOOD MAY NOT BE IN
OPERATION RESULTING IN INADEQUATE VENTING!
INITIAL PILOT LIGHTING:
CAUTION: When lighting pilots and checking for leaks, do not stand with your face close to the
combustion chamber.
Check for Gas Leaks:
1. Remove the kick plate and the component cover at the rear of the oven
2. Check pilot tubing and burner tubing for leaks at the connectors with a soapy water solution.
3. Light the pilot as described above.
4. Turn the thermostat to any setting and the burner should light.
5. Check the burner orifice elbow connection downstream of the valve with a soapy water
solution.
6. Check the burner visually for blue flame. There should be no yellow tips or soot. If yellow tipping
occurs, call an authorized service person to adjust the burner air shutter.
Disclaimer:
All MARKET FORGE INDUSTRIES, INC. appliances are adjusted and tested before leaving the factory,
effectively matching them to sea level conditions. Adjustments and calibrations to assure proper
operation may be necessary on installation to meet local conditions; low gas characteristics, to correct
possible problems caused by rough handling or vibration during shipment, and are to be performed only
by qualified service personnel. These adjustments are the responsibility of the customer and/or dealer
and are not covered by our warranty.
