d. Copy of the inspection report issued by carrier
representative at the time damage is reported to
the carrier. The carrier is responsible for making
prompt inspection of damage and for a thorough
investigation of each claim. The distributor or
manufacturer will not accept claims from dealers
for transportation damage.
NOTE: When inspecting the unit for transportation damage,
remove all packaging materials. Recycle or dispose of the
packaging material according to local codes
Unit installation
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
UNIT INSTALLATION
To 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
WARNING
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.
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 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.
• Close to the wall application assure free, unobstructed
air to the other two sides. In more confined application
spaces, such as corners provide a minimum 12"
clearance on all air inlet sides. Allow 36" minimum for
service access to the compressor compartment and
controls.
• Unit should be located a minimum of 3" away from the
wall with the connections facing the wall
