REGULATED GAS PRESSURE
1. Let the oven run u p to 510_F (266_C). Program
the belt for 7 minutes. You may now verify the
operational and regulated gas pressures.
Incoming static gas pressure to the unit, w ith all the
gas appliances drawing from t he supply, should be
a minimum of 5.5” W.C. (13.7 mbar) for natural gas
and 11” W.C. (28 mbar) for propane gas. The man -
ifold pressure, if measured after the regulator lo-
cated inside the control box, must be 3.5” W.C. (9
mbar) for natural gas and 10” W.C. (25 mbar) for
propane gas.

needed, turn the adjusting screw located under a
screw cap on the left front side of the dual regu -
lated valve. Adjust the gas pressure by turning the
screw clockwise to raise the gas pressure and
counter-clockwise to lower the gas pressure. Be
sure to reinstall the screw cap; should the dia-
