PRESSURE REGULATION AND TESTING
Each oven has been adjusted at the factory to op-
erate with the type of gas specified on the rating
plate attached to the left side of the control panel.
Each oven is supplied with a regulator to maintain
the proper gas pressure. The regulator is essen-
tial to the proper operation of the oven and
should not be removed. It is preset to provide the
oven with 3.5” W.C. (0.87 kPa) while the flame is
on. The regulator is located on top of the gas valve,
between the manual shutoff and solenoid valves.
DO NOT INSTALL AN ADDITIONAL REGULATOR
WHERE THE OVEN CONNECTS TO THE GAS
SUPPLY UNLESS THE SUPPLY EXCEEDS THE
MAXIMUM.
NOTE: The maximum gas supply pressure to the
oven is 10.5” W.C. (2.61 kPa). The mini-
mum gas supply pressure to the oven is
4.5” W.C. (1.1 kPa).
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 testing 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 pressure testing of the
gas piping system at test pressures equal or less
than 1/2 psig (3.45kPa).
