•
Inlet Pressure - the pressure of the gas before it reaches the oven.
•
Manifold Pressure - the pressure of the gas as it enters the main burner(s).
•
Min - the minimum pressure recommended to operate the oven.
•
Max - the maximum pressure at which the manufacturer warrants the oven’s operation.
Each oven is supplied with a regulator to maintain the proper gas pressure.
The regulator is essential to the proper op-
eration of the oven and must be installed.
It is preset to provide the oven with 3.5” W.C. (0.87 kPa) for natural gas and
10.5” W.C. (2.50 kPa) for Propane at the manifold.
DO NOT INSTALL AN ADDITIONAL REGULATOR WHERE THE OVEN CONNECTS TO THE GAS SUPPLY.
Prior to connecting the oven, gas lines should be thoroughly purged of all metal filings, shavings, pipe dope, and other de
-
bris. After connection, the oven should be checked for correct gas pressure.
Installation must conform with local codes, or in the absence of local codes, with the National Fuel Gas Code, NFPA54/
ANSI Z223.1-Latest Edition, the Natural Gas Installation Code CAN/CGA-B149.1 or the Propane Installation Code, CAN/
CGA-B149.2 as applicable.
The oven and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure test
-
ing of that system at test pressures in excess of 1/2 psig (3.45kPa).
The oven must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pres
-
sure testing of the gas piping system at test pressures equal or less than 1/2 psig (3.45kPa).
ADJUSTMENTS ASSOCIATED WITH INITIAL INSTALLATION
Each oven, and its component parts, have been thoroughly tested and inspected prior to shipment. However, it is often
necessary to further test or adjust the oven as part of a normal and proper installation. These adjustments are the respon
-
sibility of the installer, or dealer. Since these adjustments are not considered defects in material or workmanship, they are
not covered by the Original Equipment Warranty. They include, but are not limited to:
• calibration of the thermostat
• adjustment of the doors
• burner adjustments
•
leveling
• testing of gas pressure
• tightening of fasteners
No installation should be considered complete without proper inspection, and if necessary, adjustment by qualified installa
-
tion or service personnel.
