INSTALLATION

Continued

1.Provide propane supply system (see Propane Supply, page 4).

2.Connect fuel gas connector fitting on hose/regulator assembly to propane tank(s). Turn counterclockwise into threads on tank valve. Tighten firmly using wrench. IMPORTANT: Tighten regulator with vent pointing down. Pointing vent down protects regulator from weather damage.

3.Connect hose to inlet connector. Tighten firmly using a wrench. IMPORTANT: Extra hose or piping may be used if needed. Install extra hose or piping between hose/regulator assembly and propane tank. You must use the regulator supplied with heater.

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, close propane supply valve and open again slowly.

5.Check all connections for leaks.

6.Close propane supply valve.

VENTILATION

WARNING: Follow the mini- mum fresh, outside air ventila- tion requirements. If proper fresh, outside air ventilation is not provided, carbon monoxide poisoning can occur. Provide proper fresh, outside air ventila- tion before running heater.

Provide a fresh air opening of at least three square feet for each 100,000 Btu/Hr (105,500 k/j) rat- ing. Provide extra fresh air if more heaters are being used.

OPERATION

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.

TO START HEATER

1.Follow all installation, ventilation and safety information.

2.Locate heater on stable and level surface. Make sure strong drafts do not blow into front or rear of heater.

3.Plug power cord of heater into a three-prong, grounded extension cord. Extension cord must be at least six feet (1.83 m) long, UL/CSA listed and of a proper size.

Extension Cord Size Requirement

Up to 100 feet (30.5 m) long, use 16 AWG rated cord.

101 to 200 feet (30.78 to 61 m) long, use 14 AWG rated cord.

4.Plug extension cord into a 120 volt/60 hertz, three-hole, grounded outlet. Motor will start. Fan will turn, forcing air out front of heater.

5.Open propane supply valve on propane tank(s) slowly. Note: If not opened slowly, excess-flow check valve on propane tank will stop gas flow. You may hear a click from the excess-flow check valve closing. If this hap- pens, reset the excess-flow check valve by closing propane supply valve and open again slowly.
