GAS SUPPLY REQUIREMENTS
WARNING
Failure to do so can result in death, explosion or fire.
•licensed heating personnel
•authorized gas company personnel
•authorized service personnel
IMPORTANT:
TYPE OF GAS
Natural Gas:
This range is design-certified by CSA International for use with natural gas or,
after proper conversion, for use with LP gas.
This range is factory-set for use with Natural gas. The model/serial rating
plate located on the right side oven door trim has information on the types of
gas that can be used. If the types of gas listed do not include the type of gas
available, check with the local gas supplier.
•Observe all governing codes and ordinances.
•This installation must conform with all local codes and ordinances. In the
absence of local codes, installation must conform with American National
Standard, National Fuel Gas Code ANSI Z223.1 - latest edition or, in
Canada, CAN/CGA B149 - latest edition.
•Leak testing of the range must be conducted according to the
manufacturer's instructions. Do not use a flame to check for leaks.
Explosion Hazard
Use a new CSA International approved gas supply line.
Install a shut-off valve.
Securely tighten all gas connections.
If connected to LP, have a qualified person make sure gas pressure does
not exceed the maximum pressure listed in this section.
Examples of a qualified person include:

17
LP Gas Conversion:
Conversion must be performed by a qualified service technician. The qualified
agency performing this work assumes the gas conversion responsibility.
No attempt shall be made to convert the appliance from the gas specified on
the model/serial rating plate for use with a different gas without consulting
the serving gas supplier. See "GAS CONVERSION" section.
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.
•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:
Since the range must be pulled away from the installation space to provide
access to the gas regulator connections, and because hard piping restricts
movement of the range, the range can only be installed using a CSA
International-certified flexible metal appliance connector.
If local codes require a hard-piped connection, a combination of pipe fittings
must be used to connect the range to the existing gas line and maintain an
accessible working space behind the range. Consult with a qualified local
technician for an optimal connection suitable for your installation.

18
Gas shutoff valve:
A manual gas line shut-off valve must be installed 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 range.
GAS PRESSURE REGULATOR
The gas pressure regulator supplied with this range must be used. The inlet
pressure to the regulator should be as follows for proper operation:
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
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 0.5 psi gauge (14" WCP)
The range 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 0.5 psi (3.5 kPa).
Line pressure testing at 0.5 psi gauge (14" WCP) or lower
The range 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 1/2 psi (3.5 kPa).
