CAUTION: 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.
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.
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.
WARNING: 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, loss of life, 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. Failure to follow this warning could result in electrical shock, fire, personal injury, or death.
For accessory installation details, refer to the applicable installation literature.
NOTE:
Remove all shipping brackets and materials before operating the furnace.
PROCEDURE 1—LOCATION
A.
General
CAUTION: Do not install furnace in a corrosive or contaminated atmosphere. Make sure all combustion and
circulating air requirements are followed, in addition to all local codes and ordinances.
Do not use this furnace during construction when adhesives, sealers, and/or new carpets are being installed. If the furnace
is required during construction, use clean outside air for combustion and ventilation. Compounds of chlorine and fluorine
when burned with combustion air form acids which cause corrosion of the heat exchangers and metal vent system. Some
of these compounds are found in paneling and dry wall adhesives, paints, thinners, masonry cleaning materials, and many
other solvents commonly used in the construction process.
