The Fuel System: The hose/regulator as-
sembly attaches to the propane gas supply.
This provides fuel to the heater.
The Air System: The motor turns the fan. The
fan pushes air into and around the combustion
chamber. This air is heated and provides a
stream of clean, hot air.

This heater is designed to operate with a
minimum 20 lb (9 kg) propane tank. You may
need two or more tanks or one larger tank in
colder weather. It is recommended you use a
100 lb (45 kg) tank for longer operation. See
chart below. Less gas is vaporized at lower
temperatures. Your local propane gas dealer
will help you select the proper supply system.
The minimum surrounding air temperature
rating for each heater is 0° F (-18° C).
