GAS CONNECTION

MODEL
All models
Standing Pilot
Gas supply connections and any pipe joint compound must be resistant to the action of propane gases.
Location of the gas inlet is at the rear of the oven. Codes require that a gas shutoff valve must be installed
in the gas line ahead of the oven.
Connect gas supply after leveling the oven. The gas supply line must be at least the equivalent of
/ inch (19 mm) iron pipe. Make sure the pipes are clean and free of obstructions, dirt or pipe joint compound.

The ovens are equipped with fixed burner orifices which coincide with installation elevation.
Standard oven with electronic ignition is provided with a regulator integral to the gas solenoid valve and
requires no external regulator.
Ovens with standing pilot must use external regulator provided with unit, set to pressures as indicated in
above gas data chart.
The gas pressure regulator provided with Standing Pilot must be used. This regulator is set for
an outlet pressure of 3.7" W.C. (0.93 kPa) natural gas and 10" W.C. (2.5 kPa) propane gas.
Prior to lighting, check all joints in the gas supply for leaks. Use soap and water
solution. Do not use an open flame.
A. Check all joints prior to the gas valve (solenoid) before lighting unit.
B. Check all joints beyond gas valve (solenoid) after unit is lit.
After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.
TESTING THE GAS SUPPLY SYSTEM
When gas supply pressure exceeds
disconnected from the gas supply piping system.
When gas supply pressure is
system by closing its individual manual shutoff valve.
BURNER AIR ADJUSTMENT
Although main burner air is adjusted before shipment, it should be checked at the time of installation.
Excessive air will cause flames to lift off a burner when cold or may cause flash-back during normal cycling
of oven, particularly when propane gas is used.
