30" GAS RANGE INSTALLATION INSTRUCTIONS
" ON "
DO NOT allow regulator to turn on pipe
when tightening fittings.
a) Install an external manual gas shut-off valve to gas supply
line in an accessible location outside of the range. Be sure
you know where and how to shut off the gas supply to the
range.
b) Install 1/2" flare union adapter to pressure regulator using
NO MORE THAN 15ft./lbs. of torque
NOTE: Be sure to stabilize the left side of the pressure
regulator with adjustable wrench before tightening ANY
fittings to the pressure regulator (Refer to Fig. 4d).
c) Tighten the gas supply fitting and/or appliance conduit to
flare union on the right side of the pressure regulator using
NO MORE THAN 15ft./lbs. of torque.Be sure to stabilize
(For Models with Sealed Top Burners)

the 1/2" flare union adapter with an adjustable wrench
before tightening the gas supply fitting and/or appliance
conduit (Refer to Fig. 4e).
d) Install flare union adapter to external manual shut-off valve.
e) Attach appliance conduit to flare union on shut-off valve.
f) Make sure service shut-off valve on pressure regulator
is in the "ON" position (See Fig. 4f).
g) Check for 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.
Do not use flame to check for gas leaks.
Checking Manifold Gas Pressure
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.")
