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)]
at Tank
32°F (0°C)
20°F (-6.7°C)
10°F (-12.2°C)
0°F (-17.8°C)
-10°F (-23.3°C)
-20°F (-28.9°C)
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 -20°F (-29°C).

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.
