Natural Gas (NG)
This dryer is designed to operate
on natural gas. Natural gas units
have a larger orifice to accom-
modate lower pressures some-
times found with natural gas and
do not have vaporizer coils like liq-
uid propane units. A regulated
pressure of 10 PSI minimum, 30
PSI maximum must be provided
at the field connection point on the
fan and heater unit, with gas avail-
able in sufficient volume to main-
tain 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.
