VENTING REQUIREMENTS
IMPORTANT: This range must be exhausted outdoors unless you are using
ductless venting. Observe all governing codes and ordinances. Do not
obstruct flow of combustion and ventilation air.
•Do not terminate the vent system in an attic or other enclosed area.
•Use an approved vent cap for proper performance. If an alternate wall or
roof cap is used, be certain the cap size is not reduced and that it has a
backdraft damper.
•Vent system must terminate to the outside unless you are using a ductless
vent kit.
•Rigid metal vent is recommended. For best performance, do not use
plastic or metal foil vent.
•If a joist or stud must be cut, then a supporting frame must be
constructed.
•The size of the vent should be uniform.
•The vent system must have a damper.
•Seal all joints in the vent system.
•Use caulking to seal exterior wall or roof opening around the cap.
•Determine which venting method is best for your application.
Makeup Air
Local building codes may require the use of makeup air systems when using
ventilation systems greater than specified CFM of air movement. The specified
CFM varies from locale to locale. Consult your HVAC professional for specific
requirements in your area.

WARNING
ELECTRICAL SHOCK HAZARD
ELECTRICAL GROUNDING INSTRUCTIONS
•Electrically ground range.
•Failure to do so can result in death, fire or electrical shock.
•The power cord of this appliance is equipped with a three-prong
(grounding) plug which plugs into a standard three-prong grounding
wall receptacle to minimize the possibility of electric shock hazard from
this appliance.
•DO NOT, UNDER ANY CIRCUMSTANCES, CUT OR REMOVE THE (THIRD)
GROUNDING PRONG FROM THE PLUG.

18
WARNING: Improper connection of the equipment-grounding conductor can
result in a risk of electric shock. Check with a qualified electrician or service
technician if you are in doubt as to whether the appliance is properly
grounded. Do not modify the power supply cord plug. If it will not fit the
outlet, have a proper outlet installed by a qualified electrician.
ELECTRICAL CONNECTION
•The receptacle of this range is to be connected to a properly grounded
dedicated circuit providing 120 VAC/60 Hz power and protected by a 15-
or 20-Amp circuit breaker or slow blow fuse. It is recommended that a
separate circuit serving only this range be provided.
•Where a standard two-prong wall receptacle is encountered, contact a
qualified electrician to have it replaced with a properly grounded three-
prong wall receptacle.
•This range is equipped with an electronic ignition system that will not
operate properly if plugged into an outlet that is not correctly polarized.
•Electronic ignition systems operate within wide voltage limits, but proper
grounding and polarity are necessary. Check that the outlet provides 120-
volt power and is correctly grounded.
•Do not use an extension cord or an adapter plug.
•Check local codes and consult gas supplier. Check existing electrical
supply and gas supply. It is recommended that all electrical connections
be made by a licensed, qualified electrical installer.
•Range must be connected to the proper electrical voltage and frequency
as specified on the model/serial/rating plate. The plate is located on the
back panel of the range.
•It is the personal responsibility of the range owner to provide the correct
electrical service for this range.
•This gas range is not required or recommended to be plugged into a GFCI
(Ground-Fault Circuit Interrupter) outlet. It is recommended that you not
plug an electric spark ignition gas range or any other major appliance
into a GFCI wall outlet as it may cause the GFCI to trip during normal
cycling.
•Performance of this range will not be affected if operated on a GFCI-
protected circuit. However, occasional nuisance tripping of the GFCI
breaker is possible due to the normal operating nature of electronic gas
ranges.
•The wiring diagram is located on the back of the range.

19
GAS SUPPLY REQUIREMENTS
IMPORTANT:
•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/NFPA 54 - latest edition,
or in Canada, the Natural Gas and Propane Installation Code, CAN 1-1.1-
M81 - 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.
WARNING
FIRE AND 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:
-licensed heating personnel
-authorized gas company personnel
-authorized service personnel
•Failure to do so can result in death, explosion or fire.

20
TYPE OF GAS
This range is design-certified by CSA International for use with natural gas or,
after proper conversion, for use with Liquid Propane (LP) gas.
Natural Gas
This range is factory-set for use with Natural gas. The model/serial/rating
plate located on the back panel of the range 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.
LP Gas Conversion
The LP conversion kit is sold separately. 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.
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. In Canada,
flexible connectors must be single wall metal connectors less than 6 feet
(182.9 cm) in length.
•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.
