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. With Propane gas, piping
or tubing size can be 1/2" (1.3 cm) minimum. Usually,
Propane gas suppliers determine the size and materials
used in the system.
NOTE: Pipe‑joint compounds that resist the action of
Propane 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 cm) long, 5/8" (1.6 cm) or 3/4" (1.9 cm) I.D.,
flexible metal appliance connector may be used for
connecting the cooktop to the gas supply line.
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.
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:
■
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.

Gas Pressure Regulator
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: 5" (12.7 cm) WCP
Maximum pressure: 14" (35.6 cm) WCP
Propane Gas:
Minimum pressure: 10" (25.4 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 need to be
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 1/2 psi (3.5 kPa) gauge (14"
[35.6 cm] WCP)
The cooktop 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 (14"
[35.6 cm] WCP) or lower
The cooktop 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).
