WARNING
WARNING HIGH VOLTAGE!
Disconnect ALL power before servicing or installing this unit. Multiple power
sources may be present. Failure to do so may cause property damage, personal
injury or death.
Installation and repair of this unit
should be performed ONLY by indi-
viduals meeting the requirements of an "entry level tech-
nician",ataminimum, asspecified bythe Air-Conditioning,
Heating, and Refrigeration Institute (AHRI). Attempting to

CARBON MONOXIDE POISONING HAZARD
Special warning for installation of furnaces or air handling units in enclosed area such as garages, utility rooms or parking areas. Carbon monoxide producing
devices (such as automobile, space heater, gas water heater, etc.) Should not be operated in enclosed areas such as unventilated garages or utility rooms because
of the danger of carbon monoxide (CO) poisoning resulting from the exhaust emissions. If a furnace or air handler is installed in an enclosed area and a carbon
monoxide producing device is operated therein, there must be adequate direct outside ventilation. Carbon monoxide emissions can be (re)circulated throughout
the structure if the furnace or air handler is operating in any mode. CO can cause serious illness including permanent brain damage or death.
Avertissement special au sujet de l'installation d'appareils de chauffage ou de traitement d'air dans des endroits clos, tets les garages, les locaux d'entretien et les
RISQUE D'EMPOISONNEMENTAU MONOXYDE DE CARBONE
stationnements. Evitez de mettre en marche les appareils produisant du monoxyde de carbone (tels que les automobile, les appareils de chauffage autonome,etc.)
dans des endroits non ventilés tels que les d'empoisonnement au monoxyde de carbone. Si vous devez faire fonctionner ces appareils dans un endroit clos,
assures-vous qu'il y ait une ventilation directe provenant de l'exterie . Les émissions de monoxyde de carbone peuvent etre recircules dans les endroits clos,
si l'appareil de chauffage ou de traitement d'air sont en marche. Le monoxyde de carbone peut causer des maladies graves telles que des dommages permanents
au cerveau et meme la mort.
Advertencia especial para la instalación de calentadoresó maneja oras de aire en áreas cerradas como estacionamientos ó cuartos de servicio. Los equipos ó
RIESGO DE INTOXICACIÓN POR MONÓXIDO DE CARBONO
aparatos que producen monóxido de carbono (tal como automóvil, calentador de gas, calentador de agua por medio de gas, etc) no deben ser operados en
áreas cerradas debido al riesgo de envenenamiento por monóxido de carbono (CO) que resulta de las emisiones de gases de combustión. Si el equipo ó
aparato se opera en dichas áreas, debe existir una adecuada ventilac ón directa al exterior. Las emisiones de monóxido de carbono pueden circular a través
del aparato cuando se opera en cualquier modo. Elmonóxido de carbono puede causar enfermedades severas como daño cerebral permanente ó muerte.

• For bottomreturn: Failure to unfold flanges may reduce airflow by up to 18%. This could result in performance and noise issues.
³ Installer must supply one or two PVCpipes: one for combustion air (optional) and one for the flue outlet (required). Vent pipe must be either
2" or 3" in diameter, depending upon furnace input, number of elbows, length of run and installation (1 or 2 pipes). The optional Combustion
Air Pipe is dependent on installation/code requirements and must be 2" or 3" diameter PVC.

• For servicing or cleaning, a 24" front clearance is required. Unit connections (electrical, flue and drain) may necessitate greater clearances
than the minimumclearances listed above. In all cases, accessibility clearance must take precedencee over clearances fromthe enclosure
where accessibility clearances are greater.
• Important: Size fuses and w ires properly and make electrical connection in accordance with the National Electrical Code and/or all existing

Notes
• All furnaces ship as high-speed cooling and medium-speed heating. Installer must adjust blower cooling & heating speed as needed.
• For most jobs, about 400 CFMper ton when cooling is desirable.

• CFMin chart is without filter(s). Filters do not ship w ith this furnace, but must be provided by the installer. If the
furnace requires two return filters,
• INSTALLATION IS TO BE ADJUSTED TO OBTAIN TEMPERATURE RISE WITHIN THE RANGE SPECIFIED ON THE RATING PLATE.
• This chart is for information only. For satisfactory operation, external static pressure should not exceed value shown on the
ti l t
• The above chart is for U.S. furnaces installed at 0-2000 feet. At higher altitudes, a properly derated unit will have
approximately the same temperature rise at a particular CFM, w hile ESPat the CFMwill be low er.
