NOTE: Read the entire instruction manual before starting the installation.

NOTE: Please retain these instructions with the furnace after installation for future reference.

SAFETY CONSIDERATIONS

!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 combustion air requirements, gas input rate, air temperature rise, unit leveling, and unit sizing.

!WARNING

FIRE, EXPLOSION, ELECTRICAL SHOCK AND CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in personal injury, death, or property damage.

Improper installation, adjustment, alteration, service, maintenance, or use can cause carbon monoxide poisoning, explosion, fire, electrical shock, or other conditions which may cause personal injury or property damage. Consult a qualified installer, service agency, local gas supplier, or 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.

Installing and servicing 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 literature, on tags, and on labels attached to or shipped with unit and other safety precautions that may apply.

These instructions cover the 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 require these instructions as a minimum for a safe installation.

Wear safety glasses and work gloves. Have a 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 words DANGER, WARNING, and 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 a hazard which could result in personal injury or death. CAUTION is used to identify unsafe practices which may result in minor personal injury or product and property damage. NOTE is used to highlight

suggestions which will result in enhanced installation, reliability, or operation.

!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 and gloves when handling parts.

SAFE INSTALLATION REQUIREMENTS

!WARNING

FIRE, EXPLOSION, AND ASPHYXIATION HAZARD

Failure to follow this warning could result in personal injury or death.

Improper adjustment, alteration, service, maintenance or installation could cause personal injury, death and/or property damage.

Installation or repairs made by unqualified persons could result in hazards to you and others. Installation MUST conform to local codes or, in the absence of local codes, with codes of all governmental authorities having jurisdiction.

The information contained in this manual is intended for use by a qualified service agency that is experienced in such work, is familiar with all precautions and safety procedures required in such work, and is equipped with the proper tools and test instruments.

NOTE: This furnace is design-certified by the CSA International (formerly AGA and CGA) for installation in the United States and Canada. Refer to the appropriate codes, along with this manual, for proper installation.

SUse only the type of gas approved for this furnace (see Rating Plate on unit). Overfiring will result in failure of heat exchanger and cause dangerous operation. (Furnaces can be converted to

Propane gas with approved kit.)

SInstall this furnace only in a location and position as specified in “Installation” of these instructions.

SProvide adequate combustion and ventilation air to the furnace as specified in “ Combustion and Ventilation Air” of these instructions.

SCombustion products must be discharged outdoors. Connect this furnace to an approved vent system only, as specified in “Vent and Combustion Air Piping” of these instructions.

SNever 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 “Gas Supply and Piping, Final Check” of these instructions.

SAlways 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

“Technical Support Manual” of these instructions. See furnace rating plate.

SWhen a furnace is installed so that supply ducts carry air circulated by the furnace to areas outside the space containing the
