PROPANE SUPPLY
Propane gas and propane tank(s) are to be fur- nished by the user.
Use this heater only with a propane vapor withdrawal supply system. See Chapter 5 of the Standard for Storage and Handling of Liquefied Petroleum Gas, ANSI/NFPA 58 and the Propane Installation Code CAN/CGA B149.2. Your local library or fire department will have this booklet.
The amount of propane gas ready for use from pro- pane tanks varies. Two factors decide this amount:
1.The amount of propane gas in tank(s)
2.The temperature of tank(s)
The chart below shows the number of 100 pound (45 kg) tanks needed to run this heater.
Temperature [°F (°C)] | Number of tanks, |
at Tank | 100,000 Btu/Hr |
32°F (0°C) | 2 |
20°F | 2 |
10°F | 3 |
0°F | 3 |

Less gas is vaporized at lower temperatures. You may need two or more 100 pound (45 kg) tanks or one larger tank in colder weather. Your local propane gas dealer will help you select the proper supply system. The minimum surrounding air tem- perature rating for each heater is
INSTALLATION
WARNING:Reviewandunder- stand 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 pip- ing and connections for leaks after installing or servicing. Never use an open flame to check for a leak. Apply a mix- ture 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 above).
2.Connect fuel gas connector fitting on hose/regu- lator assembly to propane tank(s). Turn counter- clockwise 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 will 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.
