Oven Valve
The oven control has a flame safety device built into the body of the thermostat.
Presence of a gas ignition source (pilot) is verified by a flame safety probe. This
flame 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 flame safety device will close off gas flow to the oven burner and pilot.
The oven burner orifice is located on a brass injector stud at the rear of the oven
under the oven floor. This orifice is dedicated to the gas for which the oven is to be
used. The orifice 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
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 flame of the oven
pilot ignites main burner gas when the oven is turned on. If the pilot flame is not
present, the flame safety device will not allow pilot gas or main burner gas to flow.
In the pilot assembly shown below, the LPG ori
fi
ce is 0.14 mm. When doing
the conversion from Propane to Natural gas make sure the pilot or
ifi
ce is
changed to the NG or
ifi
ce sized at 0.2 mm. If you leave the LPG ori
fi
ce
0.14mm in place, the pilot
fl
ame will may be too small to keep the pilot lit.
