SAFETY CONSIDERATIONS
Improper installation, adjustment, alteration, service, maintenance, or
use can cause explosion, fire, electrical shock, or other conditions which
may cause death, personal injury, or property damage. Consult a
qualified installer, service agency, or your distributor or branch for
information or assistance. The qualified installer or agency must use
factory-authorized kits or accessories when modifying this product.
Refer to the individual instructions packaged with the kits or accessories
when installing.
Follow all safety codes. Wear safety glasses, protective clothing, and
work gloves. Have a fire extinguisher available. Read these instructions
thoroughly and follow all warnings or cautions include in literature and
attached to the unit. Consult local building codes, the current editions of
the current edition of National Fuel Gas Code (NFGC) NFPA 54/ANSI
Z223.1 and the current edition of National Electrical Code (NEC) NFPA
70.

The following additional safety considerations should be followed for
gas furnaces:
1. Use only with type of gas approved for this furnace. Refer to the
furnace rating plate.
2. Install this furnace only in a location and position as specified in the
“Location” section of these instructions.
3. Provide adequate combustion and ventilation air to the furnace
space as specified in “Air for Combustion and Ventilation” section.
4. Combustion products must be discharged outdoors. Connect this
furnace to an approved vent system only, as specified in the
“Venting” section of these instructions.
5. Never test for gas leaks with an open flame. Use a commercially
available soap solution made specifically for the detection of leaks
to check all connections, as specified in the “Gas Piping” section.
6. Always install furnace to operate within the furnace’s intended
temperature-rise range with a duct system which has an external
static pressure within the allowable range, as specified in the
“Start-Up, Adjustments, and Safety Check” section. See furnace
rating plate.
7. When a furnace is installed so that supply ducts carry air circulated
by the furnace to areas outside the space containing the furnace, the
return air shall also be handled by duct(s) sealed to the furnace
casing and terminating outside the space containing the furnace.
See “Air Ducts” section.
8. A gas-fired furnace for installation in a residential garage must be
installed as specified in the warning box in the “Location” section.
9. The furnace may be used for construction heat provided that the
furnace installation and operation complies with the first
CAUTION in the LOCATION section of these instructions.
10. These Multipoise Gas-Fired Furnaces are CSA (formerly A.G.A.
and C.G.A). design-certified for use with natural and propane gases
(see furnace rating plate) and for installation in alcoves, attics,
basements, closets, utility rooms, crawlspaces, and garages. The
furnace is factory-shipped for use with natural gas. A CSA listed
accessory gas conversion kit is required to convert furnace for use
with propane gas.
for required clearances to combustible construction.
12. Maintain a 1-in. (25 mm) clearance from combustible materials to
supply air ductwork for a distance of 36 inches (914 mm)
horizontally from the furnace. See current edition of NFPA 90B or
local code for further requirements.
13. These furnaces SHALL NOT be installed directly on carpeting, tile,
or any other combustible material other than wood flooring. In
downflow installations, factory accessory floor base MUST be used
when installed on combustible materials and wood flooring. Special
base is not required when this furnace is installed on manufacturer’s
coil model numbers END4X, ENW4X or coil casing model number
for clearance to combustible construction
information.
WARNING
!
FIRE, EXPLOSION, ELECTRICAL SHOCK, AND
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in dangerous operation,
serious injury, death, or property damage.
Improper installation, adjustment, alteration, service, maintenance, or
use could cause carbon monoxide poisoning, explosion, fire, electrical
shock, or other conditions which may cause personal injury or property
damage. Consult a qualified service agency, local gas supplier, or your
distributor or branch for information or assistance. The qualified
service agency must use only factory-authorized and listed kits or
accessories when modifying this product.
WARNING
!
FIRE, EXPLOSION, ELECTRICAL SHOCK, AND
CARBON MONOXIDE POINSING HAZARD
Failure to follow this warning could result in dangerous operation,
personal injury, death, or property damage.
Furnaces shall NOT be twinned (i.e. tandem or staged operation) unless
approved in factory technical specifications literature for the furnace. A
factory authorized, field-supplied Twinning Kit MUST be used.
Consult furnace pre-sale literature for specific models approved for
twinning and the correct twinning kit. Twinned furnaces must be
installed on both a common supply AND a common return duct system
as shown in the Twinning Kit Installation Instructions. Only two
furnaces can be twinned on a common supply and return duct system
using a factory authorized twinning kit.
CAUTION
!
FURNACE RELIABILITY HAZARD
Improper installation or misapplication of furnace may require
excessive servicing or cause premature component failure.
Application of this furnace should be indoors with special attention
given to vent sizing and material, gas input rate, air temperature rise,
unit leveling, and unit sizing.
CAUTION
!
CUT HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care and wear
appropriate protective clothing, safety glasses and gloves when
handling parts and servicing furnaces.
