Natural Gas; Burner Input Requirements - Whirlpool WCG55US6HB Instructions D'installation

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 should be 1/2" (1.3 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 1/2" (1.3 cm) or 3/4" (1.9 cm)
■
I.D. flexible stainless steel tubing gas connector,
designed by CSA to connect the cooktop to the rigid 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
cooktop 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.

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
1/2 psi (3.5 kPa).
Line pressure testing at 1/2 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 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).
