INSTALLATION

Natural Gas (NG)

This dryer is designed to operate on natural gas. Natural gas units have a larger orifice to accommo- date lower pressures sometimes found with natural gas and do not have vaporizer coils like liquid propane units. A regulated pres- sure of 10 PSI minimum, 30 PSI maximum must be provided at the field connection point on the fan and heater unit, with gas available in sufficient volume to maintain the operating pressure.

See the “Fuel Systems and Recommendations Chart” for natural gas to determine the cor- rect size line to run to the dryer. Have a qualified gas service per- son inspect the installation to be sure everything is installed ac-

cording to local codes and ordinances.

After installation is complete check all connections for leaks with liquid detergent or comparable. Wear rubber gloves and eye protection.

DO NOT USE FLAME FOR LEAK TESTING.

NG line field connection.
