GAS SUPPLY REQUIREMENTS 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. - Page 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.
- Page 21 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.
- Page 22 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 shut-off 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).

Page 45: Checking Operation Of The Surface Burners
CHECKING OPERATION OF THE SURFACE BURNERS Cooktop burners use electronic igniters. When the cooktop control knob is turned to the ignite position, the system creates a spark to light the burner. All or some other cooktop burners will spark, but only the burner with the control knob turned to the ignite position will produce a flame. - Page 46 QUALITY OF FLAMES The combustion quality of the burner flames needs to be confirmed visually. Soft blue flames This is normal for natural gas. Yellow tips on outer cones This is normal for LP gas. Yellow flames This is abnormal for any gas operation. Call for service.
