INSTALLATION

WARNING: Review and understand the warnings in the Safety Information section, page 2. 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: Tighten regulator with vent pointing down. Pointing vent down pro- tects regulator from weather damage.

3.Connect hose to the valve inlet. Tighten firmly using a wrench. You must use the regulator supplied with heater even if pro- pane tank has one.

4.Open propane supply valve on propane tank(s) slowly. Note: If not opened slowly, excess-flow check valve on propane tank may stop gas flow. If this happens, you may hear a click inside the regulator assembly, this is the check valve closing. To re- set the excess flow check valve, close propane supply valve and open again 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.
