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 operating properly, or the areas
may not be sufficiently ventilated. Get
fresh air at once! Have heater serviced.
Natural Gas: Natural gas has a distinc-
tive odor. This odor helps you detect a
natural gas leak. However, the odor
may fade. Natural gas may be present
even though no odor exists.

to operate on LP gas.
• Provide adequate ventilation. Before
using heater, provide at least a
three-square-foot opening of fresh,
outside air for each 100,000 Btu/Hr of
rating. This heater produces carbon
monoxide, which is listed by the
State of California as a reproductive
toxin under Proposition 65.

dwellings or in living or sleeping

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, gaso-
line, paint thinner, and other flam-
mable vapors and liquids. Dust is
combustible. Do not use heater in
areas with high dust content.
