SAFETY CONSIDERATIONS
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 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 National Fuel Gas Code (NFGC) 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
(NSCNGPIC). 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 CAUTION. These
words are used with the safety-alert symbol. DANGER identifies
the most serious hazards which will result in severe personal injury
or death. WARNING signifies hazards 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. NOTE is used to highlight suggestions that
will result in enhanced installation, reliability, or operation.
INTRODUCTION
The design of the 58EJB Deluxe Horizontal Gas-Fired Condensing
Furnace is A.G.A./C.G.A. certified as a Category IV furnace for
natural and propane gases and for installation in alcoves, base-
ments, crawlspaces, utility rooms, and attics. The design of the
horizontal gas-fired furnace is A.G.A./C.G.A. certified for instal-
lation on noncombustible floors. This furnace may be installed on
combustible wood flooring; however, it may not be installed
directly on carpeting, tile, or any combustible material other than
wood. The design of this furnace line is not A.G.A. certified for
installation in recreational vehicles, manufactured housing (mobile
homes), or outdoors.
Before installing this furnace, refer to the current edition of the
NFGC NFPA 54-1992/ANSI Z223.1-1992 which is available from
the National Fire Protection Association Inc., Batterymarch Park,
Quincy, MA 02269, American Gas Association, 1515 Wilson
Boulevard, Arlington, VA 22209, or from Literature Distribution.
In Canada, contact Standards Department of Canadian Gas Asso-
ciation, 55 Scarsdale Road, Don Mills, Ontario, Canada M3B2R3.
Installation must conform to the regulations of the serving gas
supplier and the local building, heating, and plumbing codes in
effect in the area in which the installation is made, or in the
absence of local codes with the requirements of the NFGC or
NSCNGPIC.
These instructions cover minimum requirements for a safe instal-
lation 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 pace with
changing residential construction practices. We require these
instructions as a minimum for a safe installation.
Application of this furnace should be indoors with special
attention given to vent sizing and material, gas input rate, air
temperature rise, and unit sizing. Improper installation or
misapplication of the furnace can require excessive servicing
or cause premature component failure.
This furnace is designed for a minimum continuous return-air
temperature of 60°F db or intermittent operation down to 55°F db
such as when used with a night setback thermostat. Return-air
temperature must not exceed a maximum of 85°F db.
Improper installation, adjustment, alteration, service, mainte-
nance, or use can cause carbon monoxide poisoning, explo-
sion, fire, electrical shock, or other conditions which may
cause personal injury or property damage. Consult a qualified
installer, service agency, local gas supplier, your distributor
or branch for information or assistance. The qualified installer
or agency must use only factory-authorized and listed kits or
accessories when modifying this product. Failure to follow
this warning could result in electrical shock, fire, personal
injury, or death.
