Gas Supply Line

•The gas supply line should be ½" (1.3 cm) pipe and must have an individual manual shut-o valve installed within 6 ft. (183 cm) of the dryer in accordance with the National Fuel Gas Code, ANSI Z223.1/NFPA 54, or in Canada with the Natural Gas and Propane Installation Code, B149.1.

•The shut-o valve should be easy to reach for opening and closing.

EXHAUST SYSTEM REQUIREMENTS

WARNING

This section describes the requirements for a safe and efficient exhaust system. Failure to follow these instructions can result in poor dryer performance, damage to the dryer, and a e hazard.

DUCTING

•If your current exhaust system is constructed of plastic or metal foil ßexible ducting, replace it with rigid metal ducting.

•Use only 4” (10.2 cm) diameter rigid metal ducting.

•When making turns in the ductwork, use 45° elbows rather than 90° elbows. This provides better airßow and can reduce the accumulation of lint in the exhaust system.

90° - Good 45° - Better
