SAFETY

INFORMATION

WARNINGS

IMPORTANT: Read this owner’s manual carefully and completely before trying to assemble, operate, or service this furnace. Improper use of this furnace can cause seri- ous injury or death from burns, fire, explosion, electrical shock, and carbon monoxide poisoning.

DANGER: Carbon monoxide poisoning may lead to death!

Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning resemble the flu, with headaches, dizziness, and/or nausea. If you have these signs, the furnace may not be working properly. Get fresh air at once! Have furnace serviced. Some people are more af- fected by carbon monoxide than others. These include pregnant women, people with heart or lung disease or anemia, those under the influ- ence of alcohol, and those at high altitudes.

Natural Gas: Natural gas is odorless. An odor- making agent is added to natural gas. The odor helps you detect a natural gas leak. However, the odor added to natural gas can fade. Natural gas may be present even though no odor exists.

Make certain you read and understand all warn- ings. Keep this manual for reference. It is your guidetosafeandproperoperationofthisfurnace.
