Service manual

If gas is not flowing, Remove Gas Line Tubing and

chec k f or b loc kage. If dirt or other foreign ma tter is

blocking g as f low, then the supply line should be dis-

connected and the line purged. This procedure is not

cov ered under warranty.

2) If gas is present at the Thermal Valve, and

Electrical continuity of the valve exists per Step 6,

remove and visually check the valve orifice (at the Oven

Burner or at rear of the Broiler , de pending on w hether the Oven

or Br oiler is being checked) for blockage. If none exists,

remove / replace Thermal Valve

CHECK

1) Gas pressure and supply as outlined in

the "General" section.

2) Ensure the orifice hood being used is cor-

rect for the type of gas supplied- See Chart, Page 2

3) Adjust the Oven Burner air shutter closed

until the flame is yellow, then open slightly until the

yellow disappears.

1) To calibrate the Oven Thermostat, place a

reliable o ven ther mometer on the Oven. Rotate the

ther mostat to 350°F. After 3 bur ner cycles, the oven

should ha ve r eac hed equilibrium.

2) (You'll need a knob with a hole drilled through the

center to allow a flat-tipped screwdriver to be inserted through it.)

With the knob in place, insert a thin blade, f lat-tipped

screwdriver through the knob and nest it into the small

slotted screw in the thermostat (it may be necessar y to

clear the screw of a small amount of sealant)

3) Note the temperature shown on the oven

thermometer, then, while holding the screw still with

the screwdriver, rotate the knob to the thermometer

temperature. DO NOT TURN THE CALIBRA-

TION SCREW. Reset the temperature and check for

accuracy. Repeat if necessar y.
