The gas pressure regulator must be checked at
a minimum 1" (2.5 mb) WC (water column)
above the set pressure. The inlet pressure to
the regulator should be as follows for opera-
tion and checking the regulator setting:
Natural Gas: Set pressure 5" (12.5 mb) WC;
gas supply pressure to the regulator never
to exceed 14" (34.9 mb) WC, .5 psi (3.5 kPa).
LP Gas: Set pressure 10" (25 mb) WC; gas
supply pressure to the regulator never to
exceed 14" (34.9 mb) WC, .5 psi (3.5 kPa).
L I N E P R E S S U R E T E S T I N G
Testing above .5 psi (3.5 kPa) 14" (34.9 mb)
WC (gauge): The range and its individual
shut-off valve must be disconnected from
the gas supply piping system during any
pressure testing of that system at test pres-
sures greater than .5 psi (3.5 kPa).
Testing below .5 psi (3.5 kPa) 14" (34.9 mb)
WC (gauge) or lower: The range 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 .5 psi (3.5 kPa).

IMPORTANT NOTE: All connections to the gas
piping must be wrench-tightened. Do not make
connections too tight, this may crack the gas
pressure regulator and cause a gas leak. Do
not allow the pipes to turn when tightening
fittings as the tubing in the burner box may
bend and begin to leak.
Assemble the flexible metal connector from
the gas supply pipe to the gas pressure regula-
tor. Determine the fittings required depending
on the size of your gas supply line, flexible
metal connector and shut-off valve. Refer to
the illustration below. If a flexible metal
connector is used, be sure the tubing is not
kinked. Use a pipe-joint compound made for
use with natural and LP gas.
Open the shut-off valve in the gas supply line.
Wait a few minutes for the gas to move
through the line.
Use a brush and liquid detergent to test all gas
connections for leaks. Bubbles around connec-
tions will indicate a leak. If a leak appears, shut
off the gas valve and adjust connections. Then
check connections again. Clean all the deter-
gent solution from the range.
Never test for a gas leak with a match or
other flame.
