THEORY OF OPERATION ASSEMBLY INSTALLATION

THEORY OF OPERATION

The Fuel System: The hose/regulator assembly 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.

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.

INSTALLATION

WARNING: Review and understand the warnings in the Safety Information section, pages 2 and 3. They are needed to safely operate this heater. Follow all local codes when using this heater.

WARNING: Test all gas piping and connections for leaks after installation or servicing. Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a leak. Correct all leaks at once.

1.Provide propane supply system (see Propane Supply, page 3).

2.Connect fuel gas fitting on hose/regulator assembly to pro- pane tank(s). Turn fuel gas fitting counterclockwise into threads on tank. Tighten firmly using a wrench. IMPORTANT: Posi- tion regulator so that hose leaving the regulator is in a hori- zontal position (see Figure 6, page 5). This places the regula- tor vent in the proper position to protect it from the weather.
