OVEN TEMPERATURE CALIBRATION
A. Monitor house voltage during test.
1. Must maintain at 117 VAC
From ___________to____________
B. Monitor igniter (glo-coil) current during test.
1. Must maintain 3.4 amps or greater.
From____________to_____________
C. Monitor voltage across the thermal valve connectors.
1. Must be between 3.03 and 3.3 volts A.C.
From ___________to_____________
D. Check gas pressure at the manifold (burner orifice). Light a burner during test to
equalize pressure.
1. Check to make sure 1/2" Inside Diameter (ID) supply line to the product.
2. NAT____________WCP must be 5" WCP.
3. L.P._____________WCP must be 10" WCP.
Supply pressure from the meter or L.P. tank must be at least 6" WCP for natural gas or 11"
WCP for L.P. gas. Pressure should never exceed 14" WCP or 1/2 PSI.
E. Be sure the thermostat bulb is straight and properly spaced from the oven liner. The sensor bulb
clips should be in place.
F. Place a weighted thermo-couple in the center of the oven cavity.
G. Set oven temperature control to 350*F. Oven temperature should reach 350*F in 10 minutes.
H. Cycle oven 5 times: Average 3rd, 4th and 5th cycles. Temperature is acceptable if the
average is 350*F -15F +25*F.

1. Check air shutter adjustment; sharp blue flame, no yellow tipping.
2. Check orifice hood adjustment.
