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, tags, and

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 NFPA No. 54-

1999/ANSI Z223.1-1999. In Canada, refer to the current edition of

the National Standard of Canada CAN/CGA-B149.1- and .2-M95

Natural Gas and Propane Gas Installation Codes. Wear safety

glasses and work gloves. Have fire extinguisher available during

start-up and adjustment procedures and service calls.
