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.

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-
1

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.

FLEXIBLE COUPLINGS. CONNECTOR 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.
If disconnection of the restraint is necessary, make sure to reconnect restraint after the
appliance has been returned to its originally installed posi~ion. Domestic gas or water
connectors are not suitable.
Restraining device may be attached to the back frame I panel of the unit.
If the appliance is to be installed with casters, a flexible connector must be used and the same
ANSI standards apply. Locking ITont casters are provided to limit the movement of the appliance
without depending on the connector or associated piping. A suitable strain relief must be
installed with a flexible connector.
All connections must be sealed with a joint compound suitable for LP gas and all connections
must be tested with soap water solution before lighting pilots.
INITIAL PILOT LIGHTING:
CAUTION:
When lighting pilots and checking for leaks, do not stand with your face close to the combustion
chamber.
All Market Forge 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, 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 ofthe
customer and / or dealer and are not covered by our warranty. Check all gas connections for
leaks with a soapy water solution before lighting any pilots. DO NOT USE ANY FLAME TO CHECK FOR LEAKS.Before lighting any pilots, make sure that burner valves and thermostats
are turned "off."
TOP BURNERS / RAISED GRIDDLE / BROILER:
All top section burners are equipped with constant burning pilots. These are to be manually
lighted immediately after the gas is turned on and the system is checked for leaks. Burner pilots
are provided for each burner and can be rechecked for proper adjustment. All adjustments can
be made with a screw driver to the brass pilot valve accessible through the valve cover.
GRIDDLE:
The pilot should be lighted immediately after the gas is turned on and the system is checked for
leaks. The pilot can be reached with a long match through the valve cover, or by lifting the plate
upward and accessing through the top. Adjustment of the pilot flame can be made with a
screwdriver to the pilot valve, accessible through the valve cover.
STANDARD OVEN:
Pilot gas is tapped ITom the main burner manifold pipe, routed through tubing to a safety valve,
and then to a pilot burner. Gas flow is controlled by the safety valve.
Oven pilot lighting or relighting is to be completed as follows:
m Turn the thermostat knob to "off' position and wait for 5 minutes.
m Open the oven's lower kick plate by lifting up and out. This exposes the pilot valve and the
igniter button.
3
Page 6
OPERATING INSTRUCTIONS (CONT.)
m Make sure accumulated gas if any has dispersed. Since propane gas is heavier than air,
check near the floor area for the odor of propane gas before attempting to light any pilot
burner.
m Depress the red button on the safety valve and hold it in, throughout the lighting procedure.
m Press the red button ofthe pilot ignitor and you should hear a snap and see a spark at the
pilot burner. If a spark or spark ignitor is not present apply a lit match to the pilot burner head.
m Continue to depress the safety valve button until the pilot remains lit when released.
m If pilot is extinguished, repeat steps 4 through 6 above.
m Turn the oven thermostat knob" on " and set to desired temperature setting, watch to make
sure the oven burner ignites ITom the pilot and that there are no yellow flames ftom the
burner.
m Turn the oven thermostat to the "off" and replace the lower kick plate.
NOTE: It may be necessary to relight the pilot several times until the lines are purged of any
trapped air and a constant gas flow is attained.
For complete shutdown, turn all burner valves, pilot valves and thermostats to the 'off' position.
Turn shut offvalve.
BEFORE FIRST USE - Griddles:
m Clean the griddle surface thoroughly with hot, soapy water remove to protective oil coating
applied at the factory.
m Rinse with a mixture of ~ cup vinegar to one quart water.
m Spread unsalted solid shortening or liquid frying compound evenly over the entire griddle
surface.
m Turn all griddle burners to medium and wait until the shortening begins to smoke, then turn
the burners 'off '.
m Rub the now melted shortening into the griddle surface with burlap, moving in the direction
of the surface's polish marks and covering the entire surface.
m Allow the griddle to cool.
m When the griddle is cool after the second seasoning, wipe it with a thin film of shortening or
cooking oil.
BEFORE FIRST USE -Ovens:
On initial installation turn the oven to 250o and operate for hour ,then reset the thermostat to its
maximum and operate for another hour. This will drive off any solvents remaining in the unit. At
the end of this second hour, turn the thermostat off, open the door and allow the unit to cool.
Oven should be thoroughly washed using hot soapy water before being used.
