Whirlpool WFG975H0H Installation Instructions - Page 6

Gas Supply Requirements Flexible metal appliance connector: WARNING ■ 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. Explosion Hazard Use a new CSA International approved gas supply line. Install a shut-off valve. Securely tighten all gas connections. If connected to propane, have a qualified person make sure gas pressure does not exceed 14" (36 cm) water column. Examples of a qualified person include: licensed heating personnel, authorized gas company personnel, and authorized service personnel. Failure to do so can result in death, explosion, or fire. ■ 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. Observe all governing codes and ordinances. IMPORTANT: 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 CAN/CGA B149, latest edition. IMPORTANT: Leak testing of the range must be conducted according to the manufacturer's instructions. Type of Gas Natural Gas: ■ This range is factory set for use with Natural gas. See the "Gas Conversions" section. The model/serial rating plate located on the oven frame behind the top right side of the oven door 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. Propane Gas Conversion: Conversion must be done by a qualified service technician. 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 the "Gas Conversions" 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. With Propane gas, piping or tubing size can be 1/2" (1.3 cm) minimum. Usually, Propane gas suppliers determine the size and materials used in the system. NOTE: Pipe-joint compounds that resist the action of Propane gas must be used. Do not use TEFLON®† tape. ■ Must include a shut-off 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. Shut-off 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. †®TEFLON is a registered trademark of Chemours. 6
