SAFETY CONSIDERATIONS
Installing and servicing of heating equipment can be hazardous due to gas and electrical components. Only trained personnel should install or
service heating equipment.
Untrained personnel can perform basic maintenance such as cleaning and replacing filters. All other operations should be performed by trained
service personnel. When working on heating equipment, observe precautions in the literature, on tags, and on labels attached to the unit.
Follow all safety codes. Wear safety glasses and work gloves. Have a fire extinguisher available.
Recognize safety information. This is the safety-alert symbol
. When you see this symbol on the furnace and in instructions or manuals, be
alert to the potential for personal injury.
Understand the signal words DANGER, WARNING, CAUTION, and NOTE. These words are used with the safety-alert symbol. DANGER
identifies the most serious hazards which
will
result in severe personal injury or death. WARNING signifies a hazard which
could
result in
personal injury or death. CAUTION is used to identify unsafe practices which
would
result in minor personal injury or product and property
damage. NOTE is used to highlight suggestions which
will
result in enhanced installation, reliability, or operation.
