PRESSURE REGULATION AND TESTING
The gas pressure to the appliance must be rated
for each appliance while the burners are on. A sufĆ
ficient gas pressure must be present at the inlet to
satisfy these conditions. Refer to the table below
for correct gas pressure.
Each appliance has been adjusted at the factory
to operate with the type of gas specified on the ratĆ
ing plate attached to the right side of the apĆ
pliance.
Each oven is supplied with a regulator to maintain
the proper gas pressure. The regulator is essenĆ
tial to the proper operation of the oven and
should not be removed.
DO NOT INSTALL AN ADDITIONAL REGULATOR
WHERE THE UNIT CONNECTS TO THE GAS
SUPPLY UNLESS THE INLET PRESSURE IS
GREATER THAN 14" W.C. (1/2 PSI) (37mbar).
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).
Prior to connecting the appliance, gas lines
should be thoroughly purged of all metal filings,
shavings, pipe dope, and other debris. After conĆ
nection, the appliance must be checked for corĆ
rect gas pressure.
