Theory of Operation
THE FUEL SYSTEM
The hose/regulator assembly attaches to
the propane gas supply. This provides fuel
to the heater.
THE IGNITION SYSTEM
The piezo ignitor lights the main burner.
THE AUTOMATIC CONTROL SYSTEM
This system causes the heater to shut
down if the flame goes out.
NOTE: Because of the metal lubricant
used in this product, you may notice some
smoking upon initial start-up and shut
down. This condition is normal and should
not occur beyond the first several (5-10)
minutes of operation.

• Use only original replacement parts.
This heater must use design-specific
parts. Do not substitute or use generic
parts. Improper replacement parts
could cause serious or fatal injuries.
• Keep all connections and fittings
clean. Make sure propane tank valve
outlet is clean. Check the rubber O
ring on the heater inlet fuel connec-
tor for damage before each use.
Replace if worn or damaged.
