PRESSURE REGULATOR
Since service pressure may fluctuate with local
demand, every gas cooking appliance must be
equipped with a pressure regulator on the
incoming service line for safe and efficient
operation.
The pressure regulator shipped with the
appliance has two female threads ½” NPT. The
regulator shall be installed properly in order to be
accessible when the appliance is installed in its
final position.
Manifold pressure should be checked with a
manometer and comply with the values indicated
below:
Natural gas
Æ
4.0" W.c.P.
LP/Propane
Æ
11.0" W.C.P.
Incoming line pressure upstream from the
regulator must be 1" W.c.P. higher than the
manifold pressure in order to check the
regulator.
The regulator used on this range can withstand a
maximum input pressure of 1/2 PSI (14.0" W.c.P.)
If the line pressure exceeds that amount, a step
‐
down regulator is required.
The appliance, its individual shut ‐ off valve, and
the pressure regulator must be disconnected
from the gas line during any pressure testing of
that system at pressures in excess of 1/2 psig
(3.45 kPa).
The individual manual shut ‐ off valve must be in
the OFF position during any pressure testing of
the gas supply piping system at test pressures
equal to or less than ½ psig (3.45 kPa).
