Gas Supply Line ■ Provide a gas supply line of ¾" (1.9 cm) rigid pipe to the range location. A smaller size pipe on longer runs may result in insufficient gas supply. With LP gas, piping or tubing size can be ½" (1.3 cm) minimum. Usually, LP gas suppliers determine the size and materials used in the system. NOTE: Pipe-joint compounds that resist the action of LP gas must be used. Do not use TEFLON®† tape. Flexible metal appliance connector: ■ If local codes permit, a new CSA design-certified, 4 to 5 ft (122 to 152.4 cm) long, ½" (1.3 cm) or ¾" (1.9 cm) I.D., flexible metal appliance connector may be used for connecting range to the gas supply line. ■ A ½" (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. ■ 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 opening, such as an adjacent cabinet. 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. B A C A. Gas supply line B. Shutoff valve "open" position C. To 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: Natural gas: Minimum pressure: 5" WCP Maximum pressure: 14" WCP LP gas: Minimum pressure: 11" WCP Maximum pressure: 14" WCP 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" water column pressure above the manifold pressure shown on the model/serial rating plate. Line pressure testing above ½ 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 ½ psi (3.5 kPa). Line pressure testing at ½ 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 ½ psi (3.5 kPa). †®TEFLON is a registered trademark of E.I.
