remain closed.
3. Remove the left and right hand radiation shields.
4. Remove the two (2) screws that secure the pilot bracket
and disconnect the pilot tubing at the union connection.
5. Remove the injector support and slide the burner and
burner pan forwards out of the combustion chamber.
6. Clean the burner with a stiff scrubbing brush and shake

Gas Valve
Re-greasing of the gas taps is not recommended. If the
tap spindle becomes seized or difficult to turn, refer to
Replacement of Parts section in this manual.
Thermostat Calibration
Oven
It is normal for a hydraulic thermostat cycling with a
temperature differential of 45° to 50°F. If the thermostat
is cycling beyond the 15° tolerance above or below the
set point and the appliance is under warranty, recalibrate
the thermostat or if not under warranty, consult owner for
proper action. If the thermostat is out of calibration more
than 50°, it will not likely hold an attempt of recalibration. We
suggest that the thermostat be replaced.
