• Isolate a furnace if it is installed near
an area frequently contaminated by any of the above
substances. This protects the furnace
from airborne contaminants. To ensure that the
enclosed furnace has an adequate
supply of combustion air, vent from a nearby
uncontaminated room or from outdoors. Refer to
the for
details.
• If the furnace is used in connection with a cooling coil
unit, install the furnace upstream or in parallel with the
cooling coil unit. Premature heat exchanger failure
will result if the cooling unit is placed ahead of the
furnace.
• For vertical (upow or downow) applications, the
minimum cooling coil width shall not be less than
furnace width minus 1”. Additionally, a coil installed
above an upow furnace or under a counterow
furnace may be the same width as the furnace or may
be one size larger than the furnace.
For upow applications, the front of the coil and furnace
must face the same direction.
• If the furnace is installed in a residential garage,
position the furnace so that the burners and ignition
source are located not less than 18 inches (457 mm)
above the oor. Protect the furnace from physical
damage by vehicles.
• If the furnace is installed horizontally, ensure the
access doors are not on the “up/top” or “down/bottom”
side of the furnace.
• Do not connect this furnace to a chimney ue that
serves a separate appliance designed to burn solid
fuel.
• On Counterow Installations, the air conditioning coil
must be downstream on the supply (positive) side of
the furnace heat exchanger.
•
Before setting the furnace over the plenum opening,
ensure the surface around the opening is smooth
and level. A tight seal should be made between the
furnace base and oor by using a silicone rubber
caulking compound or cement grout.
•
If installation over a combustible oor becomes
necessary, use an accessory subbase (see
Specication Sheet applicable for your model for
details.) A special accessory subbase must be
used for upright counterow unit installations over
any combustible material including wood. Refer to
subbase instructions for installation details. Follow the
instructions with the subbase for proper installation.
Do not install the furnace directly on carpeting, tile, or
other combustible material other than wood ooring.
