INTRODUCTION
Before installing the furnace, refer to “Procedures for
Natural-Draft Gas-Fired Furnaces” (packaged with the
equipment) for information concerning combustion, venting,
piping, and other standeird installation practices. Further
reference is made to the current edition of the National Fuel
Gas Code NFPA No. 54-1988/ANSI Z223.1-1988.

SAFETY CONSIDERATIONS
Installation and servicing of heating equipment can be haz­

and qualified personnel should install, repair, or service
heating equipment.
Untrained personnel can perform basic meuntenance func­
tions such as cleaning and replacing air filters. AU 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, including NFPA No. 54/ANSI
Z223.1-1988, National Fuel Gas Code. Wear safety glasses
