2.A HAZARD ALERT SYMBOL

An explanation point surrounded by a triangle.

2.B SIGNAL WORDS

Years of safe, dependable service are assured when you understand and follow all safety precautions.

Signal words “WARNING” and “CAUTION” alert you to potential hazards.

“WARNING” indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

“CAUTION” indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices. It can also be used to signal property damage only potential.

2.B. SAFETY PRECAUTIONS

These are some of our most important safety precautions; others are throughout this manual. Please read and follow them.

WARNING

Any condition that will allow gas of combustion products to enter furnace area can cause nausea, asphyxiation or fire resulting in damage, injury or death.

Natural gas and propane (LP) gas have characteristic odors. When your furnace is operating correctly, you should not smell any unfamiliar odor. Normally, burning gas with air produces combustion products which contain carbon dioxide, oxygen and water vapor. Under abnormal conditions, combustion products and contain aldehydes and carbon monoxide.

•Aldehydes have a strong pungent, acrid smell that can cause nausea.

•Carbon monoxide is tasteless, colorless and odorless. It can cause headaches, flu-like symptoms or nausea. We refer to all these symptoms as nausea in this manual. It can also cause death by asphyxiation.
