Gas Pressure Adjustments
REGULATED GAS PRESSURE
NOTE: Gas models only.
1. Let the oven heat to 510_F (266_C).
2. Check the pressure at the tap on the multi-func-
tio n gas valv e and at the tap on the tee fitti ng at
the rear of the electrical box. See Figure 15.
Incoming gas pressure to the unit, with all the gas
appliances drawing from the supply, should be a
minimum of 4.5” W.C. (11. 2 mbar) for natural gas
and 11” W.C. (27.4 mbar) for propane gas. The
maximum gas pressure should not exceed 13”
W.C. (32.3 mbar). This measurement should be
taken at the Incoming Line Pressure Tap.
The manifold pressure must be 3.5” W.C. (8.7
mbar) for natural gas and 10” W.C. (25 mbar) for
propane gas. This measurement should be taken
at the Manifold and Pilot Pressure Tap.
To adjust the manifold pressure
1. Unscrew t he regulator adjustment cover cap.
2. Turn the adjusting screw inside the gas valve.
NOTE: Turn the screw clockwise to raise the
manifold pressure and counter- c lock-
wise to lower it.
3. Reinstall the cover cap.
