Chapter 9: 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. Natu-
ral 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 sole-
noid 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.
