Flexible metal appliance connector: ■■ If local codes permit, a new CSA design-certified, 4 to 5 ft (122 to 152.4 cm) long, 1/2" (1.3 cm) or 3/4" (1.9 cm) I.D. (inside diameter), 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: The rigid pipe connection requires a combination of pipe fittings to obtain an in-line connection to the range. The rigid pipe must be level with the range connection. All strains must be removed from the supply and fuel lines so range will be level and in line. ■■ Must include a shutoff valve: Install a manual gas line shut-off valve 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. 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" (12.7 cm) WCP Maximum pressure: 14" (35.5 cm) WCP Propane Gas: Minimum pressure: 11" (27.9 cm) WCP Maximum pressure: 14" (35.5 cm) 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" (2.5 cm) water column pressure above the manifold pressure shown on the model/serial rating plate. Line pressure testing above 1/2 psi (3.5 kPa) gauge 14" (35.5 cm) 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 1/2 psi (3.5 kPa). Line pressure testing at 1/2 psi (3.5 kPa) gauge 14" (35.5 cm) 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). 7
