Chapter 8: Fuel Supply
Guidelines for Connecting Natural Gas to a Dryer
When initially installing the dryer, you must connect a fuel source before you can operate the dryer. Natural
gas (NG) is one possible fuel choice.
• Operate the dryer on natural gas with a heat value of approximately 1000 BTU (880 kWper cubic
foot).
NOTE: The dryer is equipped with a natural gas supply pipe system connected to the heater solenoid
valves.
• You must provide a regulated pressure of 15 PSI at the connection to the dryer with sufficient gas
available to maintain this operating pressure.

Specifications and Recommendations for Natural Gas
The fuel line size and heater orifice size are determined by the dryer model heat capacity and fuel flow
rate. Use the specifications chart that follows to select the appropriate equipment for your dryer.
