SAFETY
REQUIREMENTS
Recognize safety information.
This is the safety-alert
symbol/X
X.
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, or CAUTION.
These words are used with the safety-alert
symbol.
DANGER
identifies the most serious hazards, those that 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 that could result in minor personal injury or product and
property damage.
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 service 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 current edition National Fuel Gas Code (N FGC) NFPA
No. 54/ANSIZ223.1.
In Canada, refer to the current edition of the National Standard Canada CAN/CGA-B149.1
- and .2-M91 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.
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 residential
construction
practices.
We requre these instructions
as a minimum for a safe installation.
