INJURY OR DEATH, T HE F OLLOWING BULLET POINTS M UST BE O BSERVED
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 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.
WARNING

Ground Level Installations Only:

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.
Outside Slab Installation

Rooftop Installations Only:

NOTE: To ensure proper condensate drainage, unit must be
installed in a level position.
To avoid possible property damage or personal injury, the
•
roof must have sufficient structural strength to carry the
weight of the unit(s) and snow or water loads as required
by local codes. Consult a structural engineer to determine
the weight capabilities of the roof.
