ROTATION OF REAR HOUSING
If rear housing on the replacement control is in the desired position,
proceed to CONTROL MOUNTING section.
To rotate housing position, proceed as follows:
1. Gas cock must be turned to the “OFF’” position.
2. Remove four hex head bolts on rear of control and comptetely
separate housings. DO NOT turn valve or valve stem while control
is disassembled.
3. Using a small screwdriver, push in the calibration screw in the
center of the gas cock plug. Turn this screw 1/4 turn in either
direction. This will allow the slotted end of the gas cock to engage
the valve stem cross pins when the control is ressembled.
NOTE: If the above procedure is followed carefully, calibration will not
be affected when the rear housing is reassembled.
4. Reassemble rear housing with outlet down. Be certain cross pin on
end of valve stem engages slot in inner end of gas cock.
DO NOT FORCE TOGETHER. When properly aligned, rear housing
will move into position easily.
5. Replace and tighten the four hex head bolts.
CONTROL MOUNTING
NOTE: DIASTAT IS LIQUID FILLED AND SHARP BENDS ARE TO BE
AVOIDED. Recommended method to uncoil diastat is to insert a round
screwdriver shaft through the center of the diastat coil and push away
from the control body.
1. Assemble outlet fittings required into control.
2. Mount control using new manifold gasket and mounting bolts.
3. Attach pilot line.
4. Connect outlet line.
5. Turn on gas supply and leak test all connections.
DIAL STEM ASSEMBLY
lnsert “D” stem dial sleeve into front of control and snap in place.
When additional stem length is required, use stem length adaptor as
follows:
1. Place adaptor on “D” stem dial sleeve and place dial on adaptor.
2. To determine correct adaptor length, measure distance from back
edge of dial to panel front or bezel. Cut this amount off small end
of adaptor.
3. If tighter dial fit is desired, spread end of “D” stem sleeve and stem
length adaptor slightly.

BEZEL INSTALLATION
Bezel and sleeve are installed by closing center sleeve over dial guide
on the front of the control.
If standard sleeve is too short, remove from bezel. Use pliers to apply
light pressure and squeeze the adaptor slightly to disengage locking
tabs. Install correct length sleeve in bezel.
Bezel index position can be changed to match manifold mounting
position of control. Snap sleeve out of bezel as described above.
SWITCH TERMINAL CONNECTIONS
“Oven on” terminals are located on the inner side of the switch next to
the control body. “Oven ready” terminals are located on the outer side
of the switch. Terminal connections required for replacing each specific
model control are shown in the following chart.

OPERATING INSTRUCTIONS
HEATER PILOT ADJUSTMENT
1. Be sure constant burning pilot is ignited.
2. Turn heater pilot adjusting key counterclockwise to full open.
3. Turn dial to the DOT position (between “off” and “140°”), then

2.
3.
4.
Be sure constant burning pilot is ignited.
Turn by-pass adjusting key counterclockwise to full open.
Turn dial to “Broil.”
After five minutes, turn dial to the DOT position between “Off” and
“140°” and adjust flame with by-pass adjusting key so that it will
just hold on the oven burner.
SERVICE INSTRUCTIONS
TO RECALIBRATE CONTROL
The minimum flame (by-pass) on the oven burner must be properly
adjusted before checking oven temperature or recalibrating. To check
oven temperature, use a test Instrument or a reliable mercury thermometer. Temperature should be checked in the center of the oven.
Calibration Check Procedure:
1. Set dial at 400°F mark and light oven burner.
2. After burner has been on about 15 minutes, check oven
temperature. If recalibration is required, proceed as directed.
3. Remove dial assembly and “D” type stem.
4. With a screwdriver, push calibration stem inward and while holding
stem firmly in, using the screwdriver bit as a reference point, turn
stem clockwise to obtain a lower temperature or counterclockwise
for a higher temperature. Each mark on retainer represents 25
degrees. Replace dial assembly and “D” type stem with dial.
5. To check your calibration setting, open door and allow oven to cool.
Repeat steps 1, 2 and 3. Recalibrate, if necessary, following steps 4
and 5.
