SAFETY CONSIDERATIONS

Installation and servicing of heating equipment can be hazardous

due to gas and electrical components. Only trained and qualified

personnel should install, repair, or service heating equipment.

Untrained personnel can perform basic maintenance functions

such as cleaning and replacing air filters. All other operations must

be performed by trained service personnel. When working on

heating equipment, observe precautions in the literature, on tags,

and on labels attached to or shipped with the unit and other safety

precautions that may apply.

Follow all safety codes. In the United States, follow all safety

codes including the National Fuel Gas Code (NFGC) NFPA

54-1996/ANSI Z223.1-1996 and the Installation Standards, Warm

Air Heating and Air Conditioning Systems (NFPA 90B)

ANSI/NFPA 90B. In Canada, refer to the CAN/CGA-B149.1- and

.2-M95 National Standard of Canada, Natural Gas and Propane

Installation Codes (NSCNGPIC). Wear safety glasses and work

gloves. Have fire extinguisher available during start-up and

adjustment procedures and service calls.

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.

These instructions cover minimum requirements and conform to

existing national standards and safety codes. In some instances,

these instructions exceed certain local codes and ordinances,

especially those that may not have kept up with changing residen-

tial construction practices. We require these instructions as a

minimum for a safe installation.
