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).

Check and adjust the height of top burner flames. The cooktop "low" burner
flame should be a steady blue flame approximately 1/4" (6 mm) high. Propane
gas flames have a slightly yellow tip.
If burners do not light properly:
To adjust standard burner:
IMPORTANT: Adjustments must be made with two other burners in operation
on a medium setting. This prevents the upper row of flames from being set too
low, resulting in the flame being extinguished when other burners are turned
on.
The flame can be adjusted using the adjustment screw in the center of the
valve stem. The valve stem is located directly behind the control knob.

4. Check that burner caps are properly positioned on burner bases.
1. Light the burner and turn the knob to the lowest setting (MIN).
2. Pull and remove the control knob.
3. Insert a small, flat-blade screwdriver into the adjustment screw, and
slowly turn the screw until the flame appearance is correct.
• Open the valve more if the flames are too small or fluttered.
• Close the valve more if the flames are too large.
4. Replace the control knob.
5. Test and check the flame by turning the control knob from the lowest to
the highest settings.

NOTE: For burners (on some models) with safety valve, make sure that the
regulation obtained is sufficient to maintain heating of the thermocouple. If it
is not, increase the minimum flame.
ABNORMAL OPERATION
ANY OF THE FOLLOWING ARE CONSIDERED TO BE ANBORMAL OPERATION
AND MAY REQUIRE SERVICING:
IN CASE THE APPLIANCE FAILS TO OPERATE CORRECTLY, CONTACT THE
AUTHORIZED SERVICE PROVIDE IN YOUR AREA.
THE BURNERS REQUIRE NO REGULATION OF THE PRIMARY AIR.
LEVEL RANGE
IMPORTANT: Do not operate the range if its rear foot is not completely
engaged in the anti-tip bracket. Never completely remove the leveling legs or
the range will not be secured to the anti-tip device properly.
• Yellow burner flames.
• Sooting up of cooking utensils.
• Burners not igniting properly.
• Burners failing to remain lit.
• Burners extinguished by oven door.
• Gas valves, which are difficult to turn.
NOTE: The range must be level for optimum cooking and baking
performance.
1. Slide range into final location, making sure rear leveling leg slides into the
anti- tip bracket. Leave a 1" (2.5 cm) gap between the back of the range
and the back wall.
2. Check that the range is level by placing a level on the oven bottom. If
needed, use a wrench to adjust the height of the leveling legs until the
range is level from side to side and from front to back.
29
VERIFY ANTI-TIP BRACKET ENGAGEMENT
1. Place the outside of your foot against the bottom of the front panel to
keep the range from moving, and then grasp the back of the range, as
shown.
2. Slowly attempt to tilt the range forward.
• If you encounter immediate resistance, the range foot is engaged in
the anti-tip bracket. Range installation is completed.
• If the rear of the range lifts more than 1/2" (1.3 cm) off the floor
without resistance, stop tilting the range and lower it gently back to
the floor. The range foot is not engaged in the anti-tip bracket.
Proceed to Steps 3 and 4.
IMPORTANT: If there is a snapping or popping sound when tilting the
range, the range may not be fully engaged in the bracket. Check to
see if there are obstructions keeping the range from sliding to the
wall or keeping the range foot from sliding into the bracket. Verify
that the bracket is held securely in place by the mounting screws.
3. Slide the range forward, and verify that the anti-tip bracket is securely
attached to the floor or wall.
4. Slide range back so the rear range foot is inserted into the slot of the anti-
tip bracket.
IMPORTANT: If the range is pulled away from the wall for any reason, always
verify anti-tip bracket engagement again.
