INSTALLATION
READ BEFORE INSTALLING
Clearance:
When installing ovens against combustible surfaces (rear or side walls) 0” 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 number, serial number, power input, ampere draw and clearances from combustible and
non-combustible surfaces. Metal tag with serial number is located on the top right corner of the unit.
UNIT MUST BE CONNECTED ONLY TO THE POWER INPUT IDENTIFIED ON THE RATING PLATE!
Electrical Connection:
Convection ovens have a single point power connection at the terminal block. Check for single phase or
three phase connection and connect accordingly. The electrical service in the building must be equipped
with a properly grounded receptacle, in accordance with local codes, or in the absence of local codes,
with the national electrical code, ANSI/NFPA 70-latest edition, in Canada, conform with Canadian
electrical codes CSA- C22.1. 208V or 240V single and three phase wires should be properly connected as
shown in the wiring diagram. 480V connection is ONLY with three phase and a step down transformer.
Do not cut or remove the grounding wire. 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.
WARNING:
IMPROPER CONNECTION TO POWER SUPPLY OTHER THAN WHAT IS DESIGNATED ON DATE
PLATE WILL VOID WARRANTY.

Flexible Coupling, Connectors and Casters:
If the unit is to be installed with flexible couplings and /or quick-disconnect fittings, the installer must
use a AGA design-certified commercial flexible connector of at least 3/4” NPT (with suitable strain relief).
The flexible connector must comply with the standard for Connectors for Movable Gas Appliances, ANSI
Z21.69 and addendum Z21.69a (or latest edition) and a quick-disconnect device that complies with the
standard for quick-disconnect devices for use with Gas Fuel should comply with ANSI Z21.41 and
addendum Z21.41a (or latest edition). If disconnection of the restraint is necessary, make sure to
reconnect restraint after the appliance has been returned to its originally installed position. Domestic
gas or water connectors are not suitable!*Restraining device may be attached to the back frame/panel
of unit.
If the unit is to be installed with casters, a flexible connector must be used and the same ANSI standards
apply. Locking front 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 the flexible connector.
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 pilots.
Lighting:
CAUTION: When lighting pilots and checking for leaks, do not Stand with your face close to the
combustion chamber.
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. Check all gas connections for leaks with a soapy water solution
before lighting any pilots.
Final Preparation:
On initial installation, turn the oven to 250 degrees and operate for about 1 hour, then reset the
thermostat to its maximum and operate for another hour. This will drive off solvents remaining in the
unit. At the end of this second hour, turn the thermostat OFF, open the door and set the switch to ‘cool’.
Oven should then be thoroughly washed using hot, soapy water before being used.

MAINTENANCE
Any piece of equipment works better and lasts longer when maintained properly. Cooking equipment is
no exception. Your MARKET FORGE INDUSTRIES, INC. oven must be kept clean during the working day
and thoroughly cleaned at the end of the day.
CAUTION: Never use Ammonia in an Oven that is warmer than room temperature and always have
direct ventilation.
Daily Cleaning:
1. Remove the baking racks. Wash in hot soapy water, and replace after the rest of the oven is
cleaned.
2. Scrape off any food particles with a nylon griddle scraper. Be very careful about scratching the
porcelain finish on the oven liner panels.
3. Wash all the above with hot soapy water, then reassemble.
4. Baked on spills may be loosened and stubborn stains removed with ordinary household
ammonia and scrubbing with a nylon pad in a cold oven only.
5. Do not allow spray type oven cleaners to come into contact with the temperature probe in the
oven.
6. After cleaning the oven, rinse well with ¼ cup of vinegar to one quart of clear water solution to
neutralize any caustic residue of the cleaning compound. Wipe dry.
7. To increase the life of the motor, follow these instructions:
a) Never run oven with motor off.
b) After you finish cooking and the oven is not to be used for more then 1/2 hour. Place the
switch to the “COOL” position and open the door. When oven temperature is equal to
room temperature turn unit off.
Periodic Cleaning:
Check the ventilation system periodically to see that nothing has fallen down into the exhaust vents.
Lubricate the pivot pins of the oven door hinge. Use a multi-purpose lubricating oil sparingly so as to not
drip oil needlessly.
Your appliance should be checked for safe and efficient operation at least once a year by qualified
service personnel.
Cleaning Stainless Steel:
All stainless steel body parts should be wiped regularly with hot soapy water during the day and with a
liquid cleaner designed for this material at the end of each day.
DO NOT USE steel wool, abrasive cloths, cleaners or powders to clean stainless surfaces! If it is
necessary to scrape stainless steel to remove encrusted materials, soak in hot water to loosen the
material; then use a wood or nylon scraper.
DO NOT USE a metal knife, spatula, or any other metal tool to scrape stainless steel. Scratches are
almost impossible to remove.
