Gas Supply Line
■ P rovide a gas supply line of ¾" (1.9 cm) rigid pipe to
■ ■
the range location. A smaller size pipe on longer runs
may result in insufficient gas supply. With LP gas, piping
or tubing size can be ½" (1.3 cm) minimum. Usually, LP
gas suppliers determine the size and materials used in
the system.
NOTE: Pipe-joint compounds that resist the action
of LP gas must be used. Do not use TEFLON
Flexible Metal Appliance Connector:
If local codes permit, a new CSA design-certified,
■
4–5 ft (122–152.4 cm) long,
I.D. flexible metal appliance connector may be used
for connecting range to the gas supply line.
A ½" (1.3 cm) male pipe thread is needed for connection
■
to the female pipe threads of the inlet to the range
pressure regulator.
Do not kink or damage the flexible metal tubing
■
when moving the range.
IMPORTANT: All connections must be wrench-tightened.
Do not make connections to the gas regulator too tight.
Making the connections too tight may crack the regulator
and cause a gas leak. Do not allow the regulator to turn or
move when tightening fittings.
Must include a shut-off valve:
■
The supply line must be equipped with a manual shut-off
valve. This valve should be located in the same room but
external to the range opening such as an adjacent cabinet.
It should be in a location that allows ease of opening and
closing. 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" (35.6 cm) WCP
LP Gas:
Minimum pressure: 11" (27.9 cm) WCP
Maximum pressure: 14" (35.6 cm) WCP
Contact local gas supplier if you are not sure about
the inlet pressure.
Burner Input Rating – Altitude
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).
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 Gauge (14" WCP)
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 pressures in
excess of ½ psi (3.5 kPa).
Line Pressure Testing at ½ psi Gauge (14" WCP) 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 ½ psi (3.5 kPa).
