to the female pipe threads of the inlet to the appliance
pressure regulator.
Do not kink or damage the flexible metal tubing when
■
moving the range.
IMPORTANT: All connenction must be wrench-tightened. Do
not make connections to the gas regulator too tight. Making the
connection too tight may crack the regulator and cause a gas
leak. Do not allow the regulator to turn when tightening fittings.
Must include a shutoff valve:
■
Install a manual gas line shut-off valve in an easily accessible
location. Do not block access to shut-off valve. The valve is
for turning on or shutting off gas to the range.

Gas Pressure Regulator
The gas pressure regulator supplied with this range must be
used. The inlet pressure to the regulator should be as follows for
proper operation:
Natural Gas:
Minimum pressure: 6" (15.2 cm) WCP
Maximum pressure: 14" (35.5 cm) WCP
Propane Gas:
Minimum pressure: 11" (27.9 cm) WCP
Maximum pressure: 14" (35.5 cm) WCP
Contact local gas supplier if you are not sure about the inlet
pressure.
Burner Input Requirements
Input ratings shown on the model/serial rating plate are for
elevations up to 2,000 ft (609.6 m).
For elevations above 2,000 ft (609.6 m), ratings are reduced at
a rate of 4% for each 1,000 ft (304.8 m) above sea level (not
applicable for Canada).
Gas Supply Pressure Testing
Gas supply pressure for testing regulator must be at least
1" (2.5 cm) water column pressure above the manifold pressure
shown on the model/serial rating plate.
Line pressure testing above ½ psi (3.5 kPa) gauge
14" (35.5 cm) WCP
The range and its individual shutoff valve must be disconnected
from the gas supply piping system during any pressure testing of
that system at test pressures in excess of ½ psi (3.5 kPa).
Line pressure testing at ½ psi (3.5 kPa) gauge 14" (35.5 cm)
WCP or lower
The range must be isolated from the gas supply piping system
by closing its individual manual shutoff valve during any pressure
testing of the gas supply piping system at test pressures equal
to or less than ½ psi (3.5 kPa).
