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, 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-
1992/ANSI Z223.1-1992. In Canada, refer to the current edition of
the National Standard of Canada CAN/CGA- B149.1- and .2-M91
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.
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 word DANGER, WARNING, or 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 a hazard that 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.

furnace can meet this requirement.
2. A minimum clearance of 3 in. must be provided in front of the furnace for
combustion air and proper operation.
