GAS SUPPLY LINE
Provide a gas supply line of 3/4" (1.9 cm) rigid pipe to the range 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. With LP gas, piping or tubing size can
be 1/2" (1.3 cm) minimum. Usually, LP gas suppliers determine the size and materials
used in the system.
Flexible metal appliance connector:
•
If local codes permit, a new CSA design-certified, 4 - 5 ft (122 - 152.4 cm) long,
1/2" (1.3 cm) or 3/4" (1.9 cm) I.D., flexible metal appliance connector may be used
for connecting range to the gas supply line.
•
GRAPHIC – APPLIANCE 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 range.
Rigid pipe connection:
The rigid pipe connection requires a combination of pipe fittings to obtain an in-line
connection to the range. The rigid pipe must be level with the range connection. All
strains must be removed from the supply and fuel lines so range 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 range. 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 range.
