Disconnect the range and its individual shut-off valve from the gas supply piping system during any pressure testing of that system at test pressures greater than 14" of water column pressure (approximately 1/2" psig). The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 14" of water column pressure (approximately 1/2" psig).

30” GAS REAR CONTROL FREESTANDING INSTALLATION INSTRUCTIONS
Checking manifold gas pressure
Do not use flame to check for gas leaks.
Disconnect the range and its individual shut-off valve from
the gas supply piping system during any pressure testing
of that system at test pressures greater than 14” of water
column pressure (approximately 1/2” psig).
The appliance must be isolated from the gas supply
piping system by closing its individual manual shut-off
valve during any pressure testing of the gas supply piping
system at test pressures equal to or less than 14” of water
column pressure (approximately 1/2” psig).
If it should be necessary to check the manifold gas
pressure, connect manometer (water gauge) or other
pressure device to the top burner right rear orifice.
Using
a rubber hose with inside diameter of approximately 1/4,”
hold tubing down tight over orifice.
Turn burner valve on.
For an accurate pressure check have at least two (2)
other top burners burning. Be sure the gas supply (inlet)
pressure is at least one inch above specified range
manifold pressure. The gas supply pressure should never
be over 14” water column. When properly adjusted for
Natural Gas the manifold pressure is 4”. For LP/Propane
Gas the manifold pressure is 10”.
c.
Tighten the gas supply fitting and/or appliance conduit
to flare union adaptor on the right side of the pressure
regulator
(refer to Fig. 10) using NO MORE THAN
15ft./lbs. of torque. Be sure to stabilize the 1/2” flare
union adapter with an adjustable wrench before
tightening
the gas supply fitting and/or appliance
conduit.
d.
Install flare union adapter to external manual shut-off
valve (See Fig. 8).
e.
Attach flexible appliance conduit to flare union adaptor
on shut-off valve (See Fig. 8).
f.
Make sure the service shut-off valve on pressure
regulator is set to the ON position (See Fig. 11).
g.
Check for gas leaks. Turn the gas supply on to the
range and use a liquid leak detector at all joints and
conduits to check for leaks in the system.
