Locating The Unit
WARNING
To prevent death, personal injury, prop-
erty damage or equipment damage, the
following 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 com-
bustion air inlet mounted on the unit are not af-
fected 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 in-
clude swimming pools and chlorine bleaches, paint
stripper, adhesives, paints, varnishes, sealers,
waxes (which are not yet dried) and solvents used
during construction and remodeling. Various com-
mercial 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 spe-
cific distances required, consult local codes.
•
Allow clearances from the enclosure as shown in
Specification Sheet for fire protection, proper op-
eration, and service access. These clearances must
be permanently maintained.
•
The combustion air inlet and flue outlet hoods on
the front of 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.
•
Provisions must be made for adequate combustion
and ventilation air in accordance with Section 5.3,
Air for Combustion and Ventilation, of the National
Fuel Gas Code, ANSI Z223.1, or Sections 7.2, 7.3
or 7.4 of CAN/CGA B149 Installation Codes, or
applicable provisions of the local building codes.
•
When this unit is installed so that supply ducts carry
air circulated by the unit to areas outside the space
containing the unit, the return air shall also be
handled by a duct(s) sealed to the furnace casing
and terminating outside the space containing the
unit.
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 the same physical
size as the unit or slightly larger and 3 inches thick.
•
The base should also be located where no runoff of
water from higher ground can collect in the unit.
Rooftop Installations Only:
• To avoid possible personal injury or property dam-
age, 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.
• If horizontal air delivery is used, the unit may be
installed directly on wood floors or on Class A,
Class B, or Class C roof covering material.
• To avoid possible personal injury, a safe, flat sur-
face for service personnel should be provided.
• If vertical air discharge is used and the unit is
installed on combustible flooring or class A, B, or C
roofing material, then the Amana roof curb (PRC01*)
is required.
II. General Information
