3INSTALLATION
Oven Location & Electrical Connection
AIR SUPPLY AND VENTILATION
The area, around and above the appliance must be kept
clear to avoid and obstruction of air ow needed for ven-
tilation. Adequate clearance must be maintained at all
times in front and side of the appliance for servicing and
proper operation.
CLEARANCE
When installing ovens against combustible surfaces (rear
or side walls) 0” clearance is required. When installing ov-
ens against non-combustible surfaces (rear or side walls)
0” clearance is required.
LOCATION
DO NOT MOUNT oven on a curb base. Use legs/cast-
ers provided. Adequate air space at the bottom and rear
of the unit must be provided for proper venting of blower
motor. DO NOT USE door to lift or move oven!!! All ov-
ens must be installed on leg assembly or casters shipped
with the unit. The leg/stand assembly parts or casters are
shipped separately.
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 efciently.
If the oor 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 prob-
ably not return to the same position after being moved,
requiring re-leveling after each and every move.
ELECTRICAL CONNECTION
WARNING
Disconnect power supply before cleaning or
servicing.
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 electri-
cal code, ANSI/NFPA 70-latest edition, in Canada, con-
form 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 connec-
tion is ONLY with three phase and a step down trans-
former.
Do not cut or remove the grounding wire. Wiring diagram
is located on the backside of the appliance.
RATING PLATE
WARNING
UNIT MUST BE CONNECTED ONLY TO THE
POWER INPUT IDENTIFIED ON THE RATING
PLATE!
IMPROPER CONNECTION TO POWER SUP-
PLY OTHER THAN WHAT IS DESIGNATED ON
DATE PLATE WILL VOID WARRANTY.
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 sur-
faces. Metal tag with serial number is located on the top
right corner of the unit.

FLEXIBLE COUPLING, CONNECTORS AND CAST-
ERS
If the unit is to be installed with exible couplings and /
or quick-disconnect ttings, the installer must use a AGA
design-certied commercial exible connector of at least
3/4” NPT (with suitable strain relief). The exible con-
nector 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 de-
vice 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 dis-
connection of the restraint is necessary, make sure to re-
connect 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 exible connec-
tor 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 exible connector. All connections must be sealed
with a joint compound suitable for LP gas and all connec-
tions must be tested with a soapy water solution before
lighting pilots.
LIGHTING THE OVEN
CAUTION
When lighting pilots and checking for leaks,
do not stand with your face close to the com-
bustion 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 charac-
teristics, to correct possible problems caused by rough
handling or vibration during shipment, and are to be per-
formed only by qualied service personnel. These adjust-
ments are the responsibility of the customer and/or dealer
and are not covered by our warranty. Check all gas con-
nections for leaks with a soapy water solution before light-
ing 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.

OPERATION
Control Panel
OPERATING INSTRUCTIONS
1. Check that power is available to the oven.
2. Arrange shelf positions according to the item to be
cooked.
3. Close doors. Move fan switch to HIGH or LOW. Fan
should come on.
4. Set thermostat dial to desired cooking temperature.
Heat indicator light should come on
5. Allow oven to preheat for about 5-10 minutes. Pre-
heating is complete.
6. Load oven. The load should be adjacent to the oven,
so the doors will be open as short a time as possible.
7. Close doors. Set timer for desired cooking time.
8. Buzzer will sound at end of preset interval. Oven is
ready to unload.
If oven temperature is to be lowered, set the thermostat
to the desired temperature to cool interior. Press the cool
down switch. The fan will continue to run with no heat.
This will help cool down the cooking compartment more
rapidly.
For daily shutdown, place oven thermostat and power
switch in OFF position. For extended shut- down, leave
doors ajar as well.
To view product while cooking press the momentary light
switch. (see item 4).

11 MAINTENANCE
Cleaning
Any piece of equipment works better and lasts longer
when maintained properly. Cooking equipment is no ex-
ception. 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 porce-
lain nish on the oven liner panels.
3. Wash all the above with hot soapy water, then reas-
semble.
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 vin-
egar 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 instruc-
tions:
a. Never run oven with motor off.
b. After you nish 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 noth-
ing 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 efcient
operation at least once a year by qualied service person-
nel.
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.
CAUTION
DO NOT USE steel wool, abrasive cloths,
cleaners or powders to clean stainless surfac-
es! 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.
CAUTION
DO NOT USE a metal knife, spatula, or any
other metal tool to scrape stainless steel.
Scratches are almost impossible to remove.
