GAS CONNECTIONS
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 3/4" (19mm) 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 match with installation elevation.
The oven is provided with a regulator integral to the gas solenoid valve and requires no external regulator.
Natural gas pressure regulators are preset for 3.5" W.C. (Water Column) (0.87 kPa); propane gas pressure regulators are preset for 10" W.C. (2.49 kPa).
WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR LEAKS. USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.
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 1/2 psig (3.45 kPa), the oven and its individual shutoff valve must be disconnected from the gas supply piping system.
When gas supply pressure is 1/2 psig (3.45 kPa) or less, the oven should be isolated from the gas supply system by closing its individual manual shutoff valve.
ADJUSTMENTS
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
Insufficient air will cause flames to burn with a yellow tip and result in carbon accumulation in the flame chamber and heat exchanger tubes.
