SAFETY CONSIDERATIONS

Installing and servicing heating equipment can be hazardous due to

gas and electrical components. Only trained and qualified person-

nel 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, refer to the National

Fuel Gas Code (NFGC) NFPA No. 54-1996/ANSI Z223.1-1996.

In Canada, refer to the current edition of the National Standard of

Canada CAN/CGA-B149.1- and .2-M95 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 unit and in instructions or

manuals, be alert to the potential for personal injury.

Understand the signal words DANGER, WARNING, and CAU-

TION. These words are used with the safety-alert symbol. DAN-

GER identifies the most serious hazards which will result in severe

personal injury or death. WARNING signifies hazards 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.

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.
