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 modied 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 984162, in order to mount the Accutemp 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.

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 replaced with the new Reed Switch 08-6615.
Introduction
YOUR ENERGY EFFICIENT CONVECTION OVEN
MSA-SB-2600 convection ovens are electrically powered,
high capacity ovens featuring high energy efciency.
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 carefully 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, employ-
ing only the nest materials and components. Of course,
Power Saver II ovens are fully approved by UL, and other
ofcial testing authorities.
HOW THE OVEN OPERATES
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 uctuating 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
using 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.

Assembly Instructions
INTRODUCTION
The model MSA-SB-2600:
Submarine-Accessible Convection Oven contains 88 total
parts for assembly and is designed such that it can be assembled in a submarine’s galley with simple tools.
Sub-Assemblies
The total assembly is broken down into 7 sub-assemblies:
• Main Frame Assembly
• Oven Cavity Assembly
• Control Panel Assembly
• Motor/Transformer Assembly
• Inside Oven Cavity Assembly
• Door Assembly
• Outer Skin Assembly
Time Estimate
The estimated time for complete assembly is approx-
mately 6-7 hours for a rst timer or 4-5 hours for an
experienced assembler. The oven assembly can be
completed with one person, but for a more productive assembly two people are recommended.
Tools required for assembly:
• Power drill (Cordless drills 12 V or higher)
• Screw driver set
• Screw starter
• Allen wrench set
• Socket Set
• Open wrench Set
• Mallet
Sealant
Use RTV 106 high temperature silicone rubber adhesive
sealant as needed to provide a tight seal to any area that
requires it. Also use Loctite 268 on all fasteners that will
be permanently fastened.

Main Frame Assembly
3. Bolt Rear U-channel frame (3) to split base front/ rear
assembly. There are welded bolts in the corner of the
split base rear. Slip the rear u- channel over the bolts
and use a two nuts to fasten it to the frame.
Figure 4
4. Install the Frame liner support/back channel (5) with
anges facing to the rear of the oven and vent hole
positioned on the left (Viewing from front of oven).
This part will align over two welded slots but will NOT
be fastened.
5. Bolt channel frame top (6), left side, and right side,
front to back (7) to the Frame liner support/back chan-
nel and Rear U-channel frame. This will require six
¼-20 hex bolts, two for each member.
NOTE: The backside needs only nuts since the bolts
are welded to each part.
Figure 6
6. Bolt two motor/transformer supports (8) to Frame
liner support/back channel using 5/16”-18, 3-inch
bolts with spacers and two 5/16”-18 nuts per spacer.
Flanges must face inward towards each other. See
“Figure 6”.

4. Then place another U-shaped split liner gasket (3)
around the top and nish by bolting the split liner top
(1) to the rest of the cavity. Now fasten each and every bolt without moving the gaskets. Then apply silicon sealant to areas of need. As a reminder the front
face anges of the cavity must be ush.
