*It is our policy to build equipment which is design certied by U.L. However, a continuing program of product improvement makes it nec-
essary to submit new models to the agencies as they are developed and consequently not all models bear the appropriate agency labels

IMPORTANT NOTICE
NOTES:
1) Accutemp griddle mounting;
This version of the Installation Manual for the Market Forge oven model MSA-
SB-2600 includes the (4) parts (listed below) that were modied in order to
accept the Accutemp Griddle being mounted on top. All ovens shipped from
the Market Forge factory with a Serial Number less than #226167 will require
a back t kit, Market Forge part number 98-4162, in order to mount the Ac-
cutemp griddle. The back t kit includes the updated version of the (4) parts
listed below and installation instructions. A simple replacement of these (4)
parts with the back t kit parts will allow the griddle to be mounted on top.
The tools required to perform the replacement are a slotted screwdriver and
a 7/16” socket wrench.

98-3587 REAR TOP PANEL
2) Replacement Reed Switch;
This version of the Installation Manual for the Market Forge oven model
MSA-SB-2600 includes a new part number for the Reed Switch (sometimes
referred to as a Proximity Switch). Due to alignment issues with the original
Reed Switch a new, more forgiving Reed Switch is now being used. The new
Reed Switch part number 08-6615 should be used as a direct replacement
for part number 08-6308 in older model MSA-SB-2600 ovens.
All ovens shipped from the Market Forge factory with a Serial Number less than
#225207 will have the original Reed Switch 08-6308. These can be directly re-
placed with the new Reed Switch 08-6615.

YOUR ENERGY EFFICIENT CONVECTION OVEN
HOW THE OVEN OPERATES
MSA-SB-2600 convection ovens are electrically powered, high
capacity ovens featuring high energy efciency. These ovens
are designed to radically cut power consumption, delivering the
cooking power of a 16 KW oven from only 11 KW’s of energy
input. Improvement of energy use is made possible by a care-
fully designed insulating system which keeps heat inside the
oven longer.
A convector fan distributes heat uniformly throughout the oven
interior, for fast even roasting and baking.
Like all Market Forge products, MSA-SB-2600 ovens are built
to the highest standards of workmanship, employing only the
nest materials and components. Of course, Power Saver
II ovens are fully approved by UL, and other ofcial testing
authorities.
MSA-SB-2600 ovens operate by use of two simple controls, a
power switch for turning on the fan motor and control circuit,
and a thermostat for setting the oven temperature. The oven is
otherwise automatic. A thermostat maintains oven temperature
by cycling heating elements on and off, with temperature uc-
tuating no more than 20°F from the setting. Uniform distribution
of heat within the oven is assured by continuous operation of a
convector fan.
A 60-minute and Constant Heat timer serves as an aid in us-
ing the oven, when the timer expires the heating elements shut
off. To prevent unnecessary loss of heat when the doors are
opened, an interlock switch stops fan operation whenever the
right-side door is opened. Should the operator wish to cool
the oven, opening just the left- side door will quickly ventilate
the oven interior.

OPERATING CONTROLS & INDICATORS
1
The controls required to operate the oven are listed in
the following table together with a short functional de-
scription of each. The physical location of each control
is shown in FIG.1.
Check that power is available to the oven
Arrange shelf positions according to the item to be
cooked.
Close doors. Move fan switch to HIGH or LOW.
Fan should come on.
Set thermostat dial to desired cooking temperature.
Element indicator light should come on
Allow oven to preheat for about 5-10 minutes. Pre-
heating is complete when indicator light goes out
and the buzzer sounds. Do not waste energy by
turning the oven on too early.
Load oven. The load should be adjacent to the
oven, so the doors will be open as short a time as
possible.
Close doors. Set timer for desired cooking time.
Buzzer will sound at end of preset interval. Oven is
ready to unload.
If oven temperature is to be lowered, set the ther-
mostat to the desired temperature to cool interior.
Fan will continue to run with left door open and right
door closed. Where indicator light comes on, oven
is at lower temperature. Close left door. When light
goes off, oven is ready for use.
For daily shutdown, place oven thermostat and
power switch in OFF position. For extended shut-

CLEANING/PREVENTIVE MAINTENANCE
TROUBLE-SHOOTING GUIDE
A good preventive maintenance program in the form of daily clean-
ing procedures is outlined in the following steps:
Remove oven shelves and wash in mild detergent and water.
Rinse and dry.
Remove left and right hand shelf supports by lifting up and out
toward center of oven. Wash, rinse and dry.
Remove fan bafe by lifting up and out. Wash, rinse and dry.
Wash interior sides, bottom, and top with mild detergent and
water. A stainless steel cleaner (not polish) should be used for
the interior. Rinse and dry.
Replace fan bafe, shelf supports and shelves.
Wash both sides of doors, top & bottom trim using a stainless
