UNIT LOCATIONS
WARNING
T
O PREVENT POSSIBLE EQUIPMENT DAMAGE, PROPERTY DAMAGE, PERSONAL
INJURY OR DEATH, THE FOLLOWING BULLET POINTS MUST BE OBSERVED
WHEN INSTALLING THE UNIT.
ALL INSTALLATIONS:
• For proper flame pattern within the heat exchanger and proper
condensate drainage, the unit must be mounted level.
• The flue outlet hood must be at least 12 inches from any
opening through which flue gases could enter a building,
and at least three feet above any forced air inlet located within
ten feet. The economizer/manual fresh air intake/motorized
fresh air intake and combustion air inlet mounted on the unit
are not affected by this restriction.
• To avoid possible corrosion of the heat exchanger, do not
locate the unit in an area where the outdoor air (i.e.
combustion air for the unit) will be frequently contaminated
by compounds containing chlorine or fluorine. Common
sources of such compounds include swimming pool
chemicals and chlorine bleaches, paint stripper,
adhesives, paints, varnishes, sealers, waxes (which are
not yet dried) and solvents used during construction and
remodeling. Various commercial and industrial processes
may also be sources of chlorine/fluorine compounds.
• To avoid possible illness or death of the building occupants,
do NOT locate outside air intake device (economizer, manual
fresh air intake, motorized fresh air intake) too close to an
exhaust outlet, gas vent termination, or plumbing vent outlet.
For specific distances required, consult local codes.
• Allow minimum clearances from the enclosure for fire
protection, proper operation, and service access (see
appendix). These clearances must be permanently
maintained.
• The combustion air inlet and flue outlet hoods on the unit
must never be obstructed. If used, do not allow the
economizer/manual fresh air damper/ motorized fresh air
damper to become blocked by snow or debris. In some
climates or locations, it may be necessary to elevate the
unit to avoid these problems.
• When the unit is heating, the temperature of the return air
entering the unit must be between 50° F and 100° F.
• Units manufactured on or after May 1, 2017 are not permitted
to be used in Canada for heating of buildings or structures
under construction.
GROUND L EVEL I NSTALLATIONS O NLY:
• When the unit is installed on the ground adjacent to the
building, a level concrete (or equal) base is recommended.
Prepare a base that is 3” larger than the package unit
footprint and a minimum of 3” thick.
• The base should also be located where no runoff of water
from higher ground can collect in the unit.

CO can cause serious illness including permanent brain
damage or death.
Advertencia especial para la instalación de calentadores ó manejadoras

El monóxido de carbono puede causar enfermedades severas
como da ño cerebra l p ermanente ó muerte.
Las emisiones de monóxido de carbono pueden circular a través

RISQUE D'EMPOISONNEMENT AU
MONOXYDE DE CARBONE
Le monoxyde de
des
carbone peut causer des maladies graves telles que
dommages permanents au cerveau et meme la mort.
Cette ventilation est nécessaire pour éviter le danger d'intoxication
au CO pouvant survenir si un appareil produisant du monoxyde
de carbone continue de fonctionner au sein de la zone confinée.
