Gas Supply Line
Provide a gas supply line of 3/4" (1.9 cm) rigid pipe to the
■
cooktop location. A smaller size pipe on longer runs may
result in insufficient gas supply. Pipe-joint compounds that
resist the action of Propane gas must be used. Do not use
TEFLON tape. With Propane gas, piping or tubing size can
®†
be 1/2" (1.6 cm) minimum. Usually, Propane gas suppliers
determine the size and materials used in the system.
Flexible metal appliance connector:
If local codes permit, use a 5/8" (1.6 cm) flexible stainless
■
steel tubing gas connector, designed by CSA to connect
the cooktop to the rigid gas supply line.
NOTE: For multi-unit installations, a single shut-off valve
is acceptable. Each unit must have its own regulator
(supplied with the unit) and flexible stainless steel tubing
gas connector.
A 1/2" (1.3 cm) male pipe thread is needed for
■
connection 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 cooktop.
Must include a shut-off 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 cooktop.

The gas pressure regulator supplied with this cooktop must be
used. The inlet pressure to the regulator should be as follows for
proper operation:
Natural Gas:
Minimum pressure: 15.2 cm WCP
Maximum pressure: 35.5 cm WCP
Propane Gas:
Minimum pressure: 27.9 cm WCP
Maximum pressure: 35.5 cm WCP
Contact local gas supplier if you are not sure about the inlet
pressure.
NOTE: For multi-unit installations, each unit must have its own
regulator (supplied with the unit).
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).
For elevations above 6,560 ft (1999.5 m), a high altitude kit
is needed to avoid any reduced power output. See separate
Propane gas conversion instructions sheet.
Line pressure testing above 1/2 psi (3.5 kPa) gauge
(35.6 cm WCP)
The appliance 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
1/2 psi (3.5 kPa).
Line pressure testing at 1/2 psi (3.5 kPa) gauge
(35.6 cm WCP) or lower
C
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 1/2 psi (3.5 kPa).
