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.

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" (152.4mm) 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 and vented to the outside; otherwise, the installation of any such device will void all oven certifications and warranties. When the diverter is supplied, it may be connected to a Type “B” vent.
BEFORE FIRST USE
Before using the oven for the first time, it must be "burned in" to release any odors that might result from heating the new surfaces in the chamber.
Using a clean damp cloth, wipe the inside of the oven, including the racks.
Close the oven doors, turn the ON/OFF/COOLDOWN switch ON, turn the thermostat to 300°F (149°C) and allow the oven to cycle for 6 to 8 hours before turning the switch OFF.
