SAFETY INFORMATION
Read and understand this manual before using
this heater. Improper use of this heater can cause
serious injury. Do not allow anyone who has not
read this manual to operate this heater. Keep this
manual for reference. It is your guide to safe and
proper operation of this heater.
1. For outdoor use only. Do not use inside house,
camper, tent, vehicle, or any type of unvented
or enclosed area.
2. Use heater in areas free from open flames,
combustible vapors, and dust.
3. Never operate heater while sleeping or unat-
tended.
4. Minimum heater clearances from combus-
tibles: Top, Front, and Sides: 3 ft (1 m)
5. This heater consumes air. Provide a fresh air
opening of at least 12 inches 2 (77 cm 2 ).
6. Use only propane gas set up for vapor with-
drawal.
7. The LP gas cylinder must be constructed and
marked in accordance with the specifications
for the LP gas cylinders of the US Depart-
ment of Transportation (DOT) or Transport
Canada.
8. Before each use, check heater for leaks. Never
use an open flame to check for a leak. Apply a
mixture of liquid soap and water to all joints.
Bubbles forming show a leak. Correct all leaks
at once.
9. Locate propane tank on a stable and level
surface. The heater burner must be at least 24"
(0.61 m) above the floor. Always attach heater
to propane tank in an upright position. Never
operate heater on its side or attach to propane
tank in a horizontal position. This could lead
to dangerous flare-ups or fire.
10. Keep children and animals away from
heater.
11. Do not use heater below ground level. Propane
is heavier than air. If a leak occurs, propane
gas will sink to the lowest possible level. If
you smell gas or suspect a leak, shut off the
propane tank valve at once and ventilate the
area. Do not strike a match or create any flame
or electric spark. Find and correct the leak
before attempting to light any appliance. If
you cannot correct leak, do not tamper with
heater. Return heater to nearest authorized
service center or to address on back page of
this manual, freight prepaid.
12. Do not move or handle a hot or operating
heater. Do not attach or remove a hot or op-
erating heater from the propane tank. Severe
burns may result.
13. Storage of heater is permissible only if the
cylinder is disconnected and removed from
heater.
14. Always remove heater from propane tank after
each use. Always store propane tank outdoors
in a well ventilated space out of the reach of

ing, garage, or any other enclosed area. Never

or where temperatures exceed 100° F (38° C).
15. For use with 20 lb. propane cylinders or
larger.
