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.
INSTALLATION
WARNING: Review and un- derstand the warnings in the Safety Information section, page
2.They are needed to safely op- erate this heater. Follow all local codes when using this heater.
WARNING: Test all gas pip- ing 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/regula- tor assembly to propane tank(s). Turn fuel gas fitting counterclockwise into threads on tank. Tighten firmly using a wrench. IMPORTANT: Position regulator so that hose leaving the regulator is in a hori- zontal position (see Figure 3). This places the regulator vent in the proper position to protect it from the weather.
3.Connect hose to valve inlet. Tighten firmly using a wrench. You must use the regulator supplied with heater.
4.Open propane supply valve on propane tank(s) slowly. Note: If not opened slowly,
5.Check all connections for leaks. Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak that must be corrected.
6.Close propane supply valve.
WARNING: 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 that must be cor- rected. Correct all leaks at once.
