GENERAL SAFETY INFORMATION
The duct furnace design is certifi ed by ETL for use with
natural and LP (propane) gases. ANSI and NFPA
Standards as well as Canadian installation codes
referred to in this manual are the ones that were
applicable at the time that the design was certifi ed. In
addition, the duct furnace may be installed on the
downstream side of a cooling coil, without need of a
bypass duct.
If the unit is to be installed at altitudes exceeding 2,000
feet (610m) above sea level, derate the input by 4% for
each 1,000 feet (305m) rise above sea level. Special
orifi ces are required for installations above 2,000 feet.
When units are installed in Canada, any reference to
derations at altitudes in excess of 2,000 feet (610m) are
to be ignored. At altitudes of 2,000 to 4,500 feet (610 to
1372m), the units must be orifi ced for 90% of normal
altitude rating, and be so marked in accordance with ETL
certifi cation.
The following terms are used throughout this manual, in
addition to the CSA requirements to bring attention to
the presence of potential hazards, or to impor tant
information concerning the product:
Indicates an imminently hazardous
situation which, if not avoided, will result in death,
serious injury, or substantial property damage.
Indicates an imminently hazard-
ous situation which, if not avoided, could result
in death, serious injury, or substantial property
damage.
Indicates an imminently hazardous
situation which, if not avoided, may result in minor
injury or property damage.
NOTICE: Used to notify of special instructions on
installation, operation, or maintenance which are
important to equipment but not related to personal
injury.
