Carbon Monoxide Poisoning: Some people are more affected by
carbon monoxide than others. Early signs of carbon monoxide poison-
ing resemble the flu, 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 may fade. Propane gas may
be present even though no odor exists.
