GAS CONNECTION
Gas supply connections and any pipe joint compound must be resistant to the action of propane gases.
The oven is provided with a regulator integral to the gas solenoid valve, and requires no regulator external
to the device.
A gas shutoff valve is supplied with each oven and is located at the bottom of the control panel. No tools
are required to access this valve.
Connect the oven(s) to the gas line after leveling. The gas supply line must be at least the equivalent of
3
/4" (1.9 cm) iron pipe. Make sure the pipes are clean and free of obstructions, dirt and piping compound.
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.
TESTING THE GAS SUPPLY SYSTEM
The oven and its individual shutoff valve must be disconnected from the gas supply piping system during
any pressure testing of that system at test pressures greater than
1
/2 psig (3.45 kPa).
The oven must be isolated from the gas supply piping system by closing the manual shutoff valve during
pressure testing of the gas supply system at test pressures equal to or less than
1
/2 psig (3.45 kPa).
GAS PRESSURES AND ORIFICES
Natural Gas
The burner orifices are sized to deliver the nameplate input rating (25,000 BTU/hr) at a gas manifold
pressure of 3.5" w.c. (water column) (0.8 kPa). The gas pressure regulator is integral to the gas solenoid
valve, and is factory set to supply 3.5" w.c. (0.8 kPa) as required for natural gas.
Propane Gas
The burner orifices are sized to deliver the nameplate input rating (25,000 BTU/hr) at a gas manifold
pressure of 10.0" w.c. (water column) (2.5 kPa). The gas pressure regulator is integral to the gas solenoid
valve, and is factory set to supply 10.0" w.c. (2.5 kPa) as required for propane gas.
BURNER AIR SHUTTER ADJUSTMENTS
The burner has fixed, factory adjusted air openings and requires no field adjustment.
