GAS SUPPLY REQUIREMENTS GAS SUPPLY LINE ■■ Must include 1/8" NPT minimum plugged tapping accessible for test gauge connection, immediately upstream of the gas connection to the washer/dryer. See illustration below. ■■ 1/2" IPS pipe is recommended. ■■ Must include shut-off valve: In the U.S.A.: An individual manual shut-off valve must be installed within six (6) ft. (1.8 m) of the washer/dryer in accordance with the National Fuel Gas Code, ANSI Z223.1. The location should be easy to reach for opening and closing. In Canada: An individual manual shut-off valve must be installed in accordance with the B149.1, Natural Gas and Propane Installation Code. It is recommended that an individual manual shut-off valve be installed within six (6) ft. (1.8 m) of the washer/dryer. The location should be easy to reach for opening and closing. E C A D B A. 3/8" flexible gas connector B. 3/8" pipe to flare adapter fitting C. 1/8" NPT minimum plugged tapping D. 1/2" NPT gas supply line E. Gas shut-off valve. This washer/dryer is equipped with its own permanent, flexible gas connector, design-certified by CSA International, for connecting the washer/dryer to the gas supply line. Flexible gas connector DRYER GAS CONNECTION Option 1 Rigid gas supply line: ■■ Connect your washer/dryer to the rigid gas supply line using an elbow and a 3/8" flare x 3/8" NPT adapter fitting between the stainless steel gas connector and the washer/dryer gas pipe, as needed to prevent kinking. Option 2 Approved aluminum or copper tubing: ■■ 3/8" approved aluminum or copper tubing is acceptable for lengths under 20 ft. (6.1 m) if local codes and gas supplier permit. ■■ If you are using natural gas, do not use copper tubing. ■■ Lengths over 20 ft. (6.1 m) should use larger tubing and a different size adapter fitting. ■■ If your washer/dryer has been converted to use LP gas, 3/8" LP compatible copper tubing can be used. If the total length of the supply line is more than 20 ft. (6.1 m), use larger pipe. NOTE: Pipe-joint compounds that resist the action of LP gas must be used. Do not use TEFLON®† tape. GAS SUPPLY CONNECTION REQUIREMENTS ■■ Use an elbow and a 3/8" flare x 3/8" NPT adapter fitting between the flexible gas connector and the washer/dryer gas pipe, as needed, to avoid kinking. ■■ Use only pipe-joint compound. Do not use TEFLON®† tape. BURNER INPUT REQUIREMENTS Elevations up to 10,000 ft (3,048 meters): ■■ The design of this washer/dryer is certified by CSA International for use at altitudes up to 10,000 ft (3,048 m) above sea level at the Btu rating indicated on the model/serial number plate. Burner input adjustments are not required when the washer/dryer is operated up to this elevation. Elevations above 10,000 ft (3,048 meters): ■■ When installed above 10,000 ft. (3,048 m) a 4% reduction of the burner Btu rating shown on the model/serial number plate is required for each 1,000 ft. (305 m) increase in elevation. Gas supply pressure testing ■■ The washer/dryer must be disconnected from the gas supply piping system during pressure testing at pressures greater than 1/2 psi. †®TEFLON is a registered trademark of E.I.
