SAFETY PRECAUTIONS
1. Check the heater thoroughly for damage. DO NOT operate a
damaged heater.
2. DO NOT modify the heater or operate a heater which
has been modified from its original condition.
3. Use only propane gas.
4. Use only VAPOR WITHDRAWAL propane supply. If there
is any question about vapor withdrawal, ask your
propane dealer.
5. Mount the propane cylinders vertically (shutoff valve up).
Secure them from falling or being knocked over and protect
them from damage.
6. Locate propane containers at least (USA) 7 ft. (2.13m),
(Canada) 10 ft. (3m) from the heater and do not direct
exhaust toward containers.
7. IMPORTANT Use only the hose and regulator assembly
provided with the heater. Match the color stripe on the
hangtag attached to the hose assembly with the color on the
label located near the propane inlet fitting on the heater.
Inspect hose assembly before each use of the heater. If there
is excessive abrasion or wear, or hose is cut, replace with
hose assembly listed on parts list before using heater.
8. For indoor use only. Area must be well ventilated. Figure 1.
(also see "Operating Precautions").

DISCONTINUE operation until the source of gas has been
located and corrected. Read enclosed Odor fade and Propane
Sheet for additional information about detecting propane
leaks.
10. Install the heater such that is is not directly exposed to water
spray, rain and/or dripping water.
11. Maintain minimum clearance from normal combustible
material (like paper). Figure 2.
12. Due to the high surface and exhaust temperatures, adults
and children must observe clearances to avoid burns or
clothing ignition.
13. Operate only on a stable, level surface.
14. Do not use with ductwork. Do not restrict inlet or exit.
15. Use only the electrical power specified. The electrical
