The oven should be connected to the gas line after leveling. The gas supply line must be at least the equivalent
of
3
⁄4" (19mm) iron pipe. Make sure piping is clean and free of obstructions, dirt or pipe joint 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
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 piping 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 (40,000 BTU/hr) at a gas manifold pressure
of 3.5" W.C. (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 (40,000 BTU/hr) at a gas manifold pressure
of 10" W.C (2.5 kPa). The gas pressure regulator is integral to the gas solenoid valve and is factory set to supply
10" W.C. (2.5 kPa) as required for propane gas.
BURNER AIR SHUTTER ADJUSTMENTS
The GCO Series Oven burner has fixed, factory-adjusted air openings and requires no field adjustment.
FLUE CONNECTIONS
Ventilation requirements will vary with each installation and must comply with applicable portions of NFPA
Standard #96, "Vapor Removal from Cooking Equipment," and with local codes. Keep in mind that:
The oven should be located under a hood which has an adequate connection to an exhaust duct and extends
6" (152mm) beyond the oven sides.
Clearance above the oven flue should be adequate for the flue products to escape so that there is no
interference with the heat circulation in the ovens.
Ovens may use an optional down draft diverter flue method. This optional down draft diverter must be
purchased from the oven manufacturer; otherwise, the installation of any such device will void all oven
certifications and warranties.
