General Safety Information
Carbon monoxide
poisoning may lead
to death! Some people are more
affected by carbon monoxide than
others. Early signs of carbon monoxide
poisoning resemble the flu, with
headaches, dizziness, and/or nausea. If
you have these signs, the heater may
not be working properly or the areas
may not be sufficiently ventilated. Get
fresh air at once! 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.
Make certain you read and understand
all warnings. Keep these instructions for

• Install and use
heater with care.
Follow all local ordinances and codes.
In the absence of local ordinances
and codes, refer to the Standard for
Storage and Handling of Liquefied
Petroleum Gas ANSI/NFPA 58. This
instructs on the safe storage and
handling of propane gases.-
• Use only the hose and factory preset
regulator provided with the heater.
• Use only propane gas set up for
vapor withdrawal.
• Provide adequate ventilation. Before
using heater, provide at least a six-
square-foot opening of fresh,
outside air. This heater produces
carbon monoxide, which is listed by
the State of California as a reproduc-
tive toxin under Proposition 65.
• For indoor use only. Do not use
heater outdoors.
• Do not use heater in occupied
dwellings or in living or sleeping
quarters.
• Do not use heater in a basement or
below ground level. Propane gas is
heavier than air. If a leak occurs,
propane gas will sink to the lowest
possible level and may accumulate to
explosive concentrations.
• Keep appliance area clear and free
from combustible materials, gasoline,
paint thinner, and other flammable va-
pors and liquids. Dust is combustible.
Do not use heater in areas with high
dust content.
• Minimum heater clearances from
combustibles:
Outlet: 6 Ft. Sides: 2 Ft.
Top: 6 Ft. Rear: 2 Ft.

propane tank(s). Do not point heater
at propane tank(s) within 20 feet.
• Keep propane tank(s) below 100
°
F.
• Check heater for damage before each
use. Do not use a damaged heater.

outlet (front) of heater.
• Keep heater away from strong drafts,
water spray, rain, or dripping water.
