Oven Valve
The oven control has a fl ame safety device built into the body of the thermostat.
Presence of a gas ignition source (pilot) is verifi ed by a fl ame safety probe. This fl ame
safety probe actuates the internal safety device to allow gas into the oven burner
when the oven is turned on. If there is a loss of gas ignition during operation, the fl ame
safety device will close o gas fl ow to the oven burner and pilot.
The oven burner orifi ce is located on a brass injector stud at the rear of the oven
under the oven fl oor. This orifi ce is dedicated to the gas for which the oven is to be
used. The orifi ce is not adjustable. It must be changed completely to convert from one
gas to the other. DO NOT DISCARD THE UNUSED ORIFICE. It should be saved in order
to convert the range back to its original fuel.

INCORRECT AND GOOD FLAME PATTERNS
If burner fl ames look like A, call for service.
B or C is normal burner fl ames, depending on the type of
gas you use.
With LP gas, some yellow tipping on outer cones is
normal.
QUALITY OF FLAMES
The combustion quality of burner fl ames needs to be
confi rmed visually.
A. Yellow fl ames — Call for service
B. Yellow tips on outer cones — It is normal for
LP gas
C. Soft blue fl ames — It is normal for natural
gas
Incorrect: fl ame
lifting off the burner
Good fl ame: Well-defi ned blue
fl ame with slight yellow tipping

Top Burner Height
In the pilot assembly shown below, the LPG orifi ce is
0.14 mm. When doing the conversion from Propane to
Natural gas make sure the pilot orifi ce is changed to
the NG orifi ce sized at 0.2 mm. If you leave the LPG
orifi ce 0.14 mm in place, the pilot fl ame will may be too
small to keep the pilot lit.
Oven Pilot
The oven pilot is located along the left hand side of the oven burner. It is fastened to the
pilot assembly with the thermocouple and the electrode. The fl ame of the oven pilot
ignites main burner gas when the oven is turned on. If the pilot fl ame is not present, the
fl ame safety device will not allow pilot gas or main burner gas to fl ow.
