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 (-6.7°C) 2

10°F (-12.2°C) 3

0°F (-17.8°C) 3

-10°F (-23.3°C) (Use larger tank)

-20°F (-28.9°C) (Use larger tank)

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).

INSTALLATION

WARNING: Review and under-

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.
