PRE-INSTALLATION CHECKS
Before attempting any installation, the following points should be considered:
• Structural strength of supporting members
• Clearances and provision for servicing
• Power supply and wiring
• Air duct connections
• Drain facilities and connections
• Gas piping and connections
• Location may be on any four sides of a home, manufactured
or modular, to minimize noise

NSTALLATIONS
:
• 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.
• Damper must be in open position when appliance main
burner(s) is operating.
Le registre doit être ouvert lorsque tout brûleur principal
de l’appareil est en état de fonctionnement.
• 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.

:
• 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 4” thick.
• The base should also be located where no runoff of water
from higher ground can collect in the unit.
• The top of the unit should be completely unobstructed. If
units are to be located under an overhang, there should be
a minimum of 48” clearance and provisons made to deflect
the warm discharge air out from the overhang.
