For all gas supply connections, 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
3
of
⁄
"
iron pipe. Make sure the pipes are clean and free of obstructions, dirt and piping
(1.9 cm)
4
compound.
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.
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
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
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)
valve, and is factory set to supply 3.5" w.c.
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)
valve, and is factory set to supply 10.0" w.c.
BURNER AIR SHUTTER ADJUSTMENTS
The burner has fixed, factory adjusted air openings and requires no field adjustment.
