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-

NG line field connection.
