m Before Installation please read instructions

completely and carefully.

m Do not remove permanently affixed labels,

warnings or plates from the product.

m Please observe all local and national codes and

ordnances

m Installation must conform with local codes, or in

the absence of local codes, the National Fuel Gas
Code, ANSI Z223.1(latest edition) In Canada,
installation should conform to installation codes for
gas burning appliances and equipment standard
CAN/CGA-B149.1 or the Propane installation
code,CAN/CGA-B149.2, as applicable.

m Electrical wiring to the appliance must be electric-

ally grounded 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.

INSTALLATION INSTRUCTIONS

m A manual gas shut - off valve must be installed in the gas supply line ahead of the appliance

and gas pressure regulator for safety and ease in servicing.

m The gas pressure regulator supplied must be installed on the appliance prior to connecting

the equipment to the gas line. Failure t9 install a regulator could be potentially hazardous and
will void the appliance warranty.

m 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 test pressures in excess if 0.5
PSI (0.04 kg/cm2).

m The appliance must be isolated from 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 0.5 PSI (0.04 kg/cm2).

RATING PLATE:

The rating plate is located in front of the range below the oven section. Information on this plate
includes the model, 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 (ovens only) are also located in the same area. The salamander broiler, or
cheesemelter (if included) are supplied with their own rating plates.

When communicating with the factory about a unit or requesting for special parts or information,
rating plate data is essential for proper identification.

CLEARANCES: The appliance must be kept free and clear of all combustibles.

NON-COMBUSTIBLE

HIGH SHELF ASSEMBLY:

Mount the high shelf assembly to the range with #10 sheet metal screws. If salamander broiler /
cheesemelter is to be mounted on range, read installation instructions for salamander /
cheesemelter before installing the high shelf. Care must be taken to ensure gas supply piping
and/or gas supply regulartor is not exposed to exhaust gases, or elevated temperatures.

OPERATING INSTRUCTIONS

Operation of this equipment must be performed by qualified or authorized personnel who have
read and understood the functions of the equipment.

LEVELING (Ranges equipped with Ovens):

A carpenter's spirit level should be used and placed on the oven's center baking rack and or
across the range top and the unit leveled from 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 smooth and level, the appliance may be further leveled with adjustment in the foot
of the leg. Units with castors require adjustment with shims. A unit will probably not return to the
same position after being moved, requiring relieving after each and every move.

AIR SUPPLY & 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 main-

OPERATING INSTRUCTIONS

tained around the appliance for easy servicing.
Provision should be made for any commercial, heavy duty cooking appliance to exhaust

combustion waste products to the outside of the building. Usual practice is to place the
appliance under an exhaust hood, which should be constructed in accordance to the local
codes.

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 the pilot or
burner performance and could be difficult to diagnose. Air movement should be checked during
installation. Air openings or baffles may have to be provided in the room, if pilot or burner
outrage problem persists.

GAS CONNECTION:

The gas supply (service) line must be the same size or greater than the inlet line of the
appliance. Market Forge ranges and ovens use 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 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:

Commercial cooking equipment must have a pressure regulator on the incoming service line for
safe and efficient operation, since service pressures may fluctuate on local demand. A pressure
regulator is packed inside every Market Forge range.

Failure to install the pressure regulator will void the appliance warranty

The regulators supplied along with Tri-star ranges, will have 3/4"inlet/outlet openings and are
adjusted at the factory for 5" WC( natural gas)orlO" 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 1/2" 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 the gas flow direction, it should
point downstream to the appliance. The red air vent cap on the top is part ofthe regulator and
should not be removed.

Any adjustments to the regulator should be made by qualified service p~rsonnel only with the
proper equipment.

CONNECTIONS:

Please check installer supplied intake pipes visually and / or blow them with compressed air to
clear any dirt particles, threading chips or any other foreign matter before installing a service
line. When gas pressure is applied, these particles could 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.
