PROPANE CONSTRUCTION HEATER
THEORY OF
OPERATION
The Fuel System: The hose/regulator
assembly attaches to the propane gas sup-
ply. 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.
The Ignition System: The piezo ignitor
lights the burner.
The Automatic Control System: This
system causes the heater to shut down if the
flame goes out.

the regulator vent in the proper position
to protect it from the weather.
