Checking Manifold Gas Pressure - Frigidaire FFGF3053LS Installation Instructions Manual

INSTALLATION INSTRUCTIONS - FREESTANDING GAS RANGE
c. Tighten the gas supply fi tting and/or appliance conduit
to fl are 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"
fl are union adapter with an adjustable wrench before
tightening the gas supply fi tting and/or appliance
conduit.
d. Install fl are union adapter to external manual shut-off
valve (See Fig. 8).
e. Attach fl exible appliance conduit to fl are 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.

Checking manifold gas pressure

Do not use fl ame 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 orifi ce. Using a
rubber hose with inside diameter of approximately 1/4," hold
tubing down tight over orifi ce. 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 specifi ed 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".
