SAFETY
WARNING: This product contains and/or generates chemicals
known to the State of California
to cause cancer or birth defects,
or other reproductive harm.
WARNING: Not for home or
recreational vehicle use.
WARNING: Fire, burn, inhalation, and explosion hazard.
Keep solid combustibles, such
as building materials, paper or
cardboard, a safe distance away
from the heater as recommended
by the instructions. Never use
the heater in spaces which do or
may contain volatile or airborne
combustibles, or products such
as gasoline, solvents, paint thinner, dust particles or unknown
chemicals.
We cannot foresee every use which may be
made of our heaters. Check with your local
re safety authority if you have questions
about heater use.
Other standards govern the use of fuel gases
and heat producing products for specific
uses. Your local authorities can advise you
about these.
Carbon Monoxide Poisoning: Direct-Fired
means that all of the combustion products enter the heated space. Even though this heater
operates very close to 100 percent combus-
tion efciency, it still produces small amounts
of carbon monoxide. Some people are more
affected by carbon monoxide than others.
Early signs of carbon monoxide poisoning
resemble the u, with headaches, dizziness,
and/or nausea. If you have these signs, the
heater may not be working properly. Get fresh
air at once! Check for proper ventilation and
have heater serviced.
Propane Gas: Propane gas is odorless. An
odor-making agent is added to propane gas.
The odor helps you detect a propane gas
leak. However, the odor added to propane
gas can fade. Propane gas may be present
even though no odor exists.

This is a propane, direct-red heater. Propane
is heavier than air. If propane leaks from a
connection or tting, it sinks to the oor, collecting there with the surrounding air, forming
a potentially explosive mixture. Obviously,
propane leaks should be avoided, so set up
the propane supply with utmost care. Read
Propane/LP Safety, page 4 for additional
information about detecting propane leaks.
Leak check new connections or reconnections
with a soap and water solution and follow all
connection instructions herein. Also, ask your
propane dealer for advice on the propane application and supply installation and ask them
to check it if there are any questions.
When the heater is to be operated in the presence of other people the user is responsible
for properly acquainting those present with
the safety precautions and instructions, and
of the hazards involved.
Make certain you read and understand all
warnings. Keep this manual for reference. It
is your guide to safe and proper operation of
this heater.
1. Check heater thoroughly for damage. DO
NOT operate a damaged heater.
2. DO NOT modify heater or operate a
heater which has been modied from its
original condition.
3. Use only propane/LP gas.
4. Use 20 lb. propane/LP tank or larger.
5. Use only VAPOR WITHDRAWAL pro-
pane supply. The propane cylinder must
be arranged for vapor withdrawal, in
accordance with the Compress Gas Associations, Small Propane Bottle Assembly. If there is any question about vapor
withdrawal, ask your propane dealer.
6. Always fully assemble heater before
each use. Do not use this heater without
securing fuel tank as instructed. Minimum
clearance from fuel tank to ground is 2".
7. Use only hose and regulator assembly
provided with heater.
8.
Inspect hose assembly before each use of
heater. If there is excessive abrasion or wear,
or hose is cut, replace with hose assembly
listed on parts list before using heater.
9. This heater is for OUTDOOR USE ONLY,
even so, make sure that there is ample
fresh air ventilation. Do not use in build-
ings, garages or other enclosed spaces.

10. If at any time gas odor is detected, IM-
MEDIATELY DISCONTINUE operation
until source of gas has been located and
corrected. Read Propane/LP Safety, page
4 for additional information about detecting propane leaks.
11. Install heater such that it is not directly
exposed to water spray, rain and/or dripping water.
12. Maintain minimum clearance to people or
normal combustible material (like paper)
of 18" (0.46 m) from top and 18" (0.46 m)
from the reector.
13. Operate only on a stable, level surface.
14. Do not spray aerosols near heater during
use or shortly thereafter.
15. Do not clean heater with combustible
or corrosive cleaners. Use warm, soapy
water on external surfaces only. Do not
submerge in water.
16. Check control compartment burners and
circulation air passageways for free air
passage, make sure that there are no
obstructions. These areas are a com-
mon location for spider webs, which can
present a dangerous condition, damage
the heater and render it unsafe for use.
The heater must be checked if any of the
following conditions exist:
a) Gas smell.
b) Heater does not reach temperature.
c) Uneven burner glow.
d)
Burner makes popping noises during normal use, other than during shutdown.
17. Use only soapy water (1 part liquid dish
washing detergent to 3 parts water) to con-
duct leak tests whenever a propane cylinder
is connected. Bubbles indicate a leak.
18. Do not adjust gas regulator. If you are
unsure of your appliances gas type or
pressure, call a qualied service person.
19. Always disconnect gas supply after heater
is turned OFF.
20. Do not move, handle or service while hot
