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 LP gas must be used. Do not use
TEFLON

tape. With LP gas, piping or tubing size can be ½"
minimum. Usually, LP gas suppliers determine the size and
materials used in the system.
Flexible metal appliance connector:
■
If local codes permit, use a
⁵⁄₈
" flexible stainless steel
tubing gas connector, designed by CSA to connect the
cooktop to the rigid 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 appliance
pressure regulator.
■
Do not kink or damage the flexible metal tubing when
moving the cooktop.
Rigid pipe connection:
The rigid pipe connection requires a combination of pipe
fittings to obtain an in-line connection to the cooktop. The
rigid pipe must be level with the cooktop connection. All
strains must be removed from the supply and fuel lines so
cooktop will be level and in line.
■
Must include a shutoff valve:
The supply line must be equipped with a manual shutoff
valve. This valve should be located in the same room but
external to the cooktop. It should be in a location that allows
ease of opening and closing. Do not block access to shutoff
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: 6" (15.2 cm) WCP
Maximum pressure: 7" to 14" (17.8 cm to 35.5 cm) WCP
LP Gas:
Minimum pressure: 11" (27.9 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 are 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
Line pressure testing above ½ psi gauge (14" 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 gauge (14" 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).
