INTRODUCTION
Instructions to be followed in the event the user smells gas shall be posted in a prominent location in
the kitchen area. This information shall be obtained by consulting the local gas supplier. Retain this
manual for future reference.
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).
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.
Air Supply and Ventilation:
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.
3
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
UNIT MUST BE CONNECTED ONLY TO THE TYPE OF GAS IDENTIFIED ON THE RATING PLATE!
READ BEFORE INSTALLING
Clearance:
When installing ovens against combustible surfaces (rear or side walls) 6” (152mm) clearance is
required. When installing ovens against non-combustible surfaces (rear or side walls) 0” clearance is
required.
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 oven 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.
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:
Single Deck oven requires one gas connection. Stacked oven requires two gas connections. 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.
