Gas Supply Line
■
Provide a gas supply line of ³⁄
4
” (19 mm) 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 should be ½” (13 mm) minimum. Usually, Propane
gas suppliers determine the size and materials used in the
system.
Flexible metal appliance connector:
■
If local codes permit, use a ¹⁄
2
” (13 mm) or ³⁄
4
” (19 mm)
I.D. flexible stainless steel tubing gas connector,
designed by CSA to connect the cooktop to the rigid gas
supply line.
■
A 1 /
2
" (13 mm) male pipe thread is needed for connection
to the female pipe threads of the inlet to the cooktop
pressure regulator.
■
Do not kink or damage the flexible metal tubing when
moving the cooktop.
■
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 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: 7” to 14” (17.8 cm to 35.5 cm) WCP
Propane Gas:
Minimum pressure: 10” (25.4 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 should 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” [35.5 cm] WCP)
The cooktop 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 cooktop 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).
