• Isolate a non-direct furnace from an area con-
taminated by any of the above substances. This
protects the non-direct vent furnace from air-
borne contaminants. To ensure that the enclosed
non-direct vent furnace has an adequate supply of
combustion air, air must be ducted in from a near-
by uncontaminated room or from outdoors. Refer
to the Combustion and Ventilation Air Require-
ments for details.
• If the furnace is used in connection with a cooling
unit, install the furnace upstream or in parallel
with the cooling coil. Premature heat exchang-
er failure will result if the cooling coil is placed
upstream of the furnace.
• For vertical (upflow or downflow) applications,
the minimum cooling coil width shall not be less
than furnace width minus 1". Additionally, a
coil installed above an upflow furnace or under
a counterflow furnace may be the same width
as the furnace or may be one size larger than
the furnace. Example: a "C" width coil may be
installed with a "B" width furnace.
• For upflow 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 floor. 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 flue that
serves a separate appliance designed to burn solid
fuel.
• On Counterflow Installations, the air conditioning
coil must be downstream on the supply (positive)
side of the furnace heat exchanger.
• Counterflow Installation over a noncombustible
floor. 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 floor by using a sili-
cone rubber caulking compound or cement grout.
• Counterflow Installation over a combustible floor.
If installation over a combustible floor becomes
necessary, use an accessory subbase (see Specifi-
cation Sheet applicable for your model for de-
tails.) A special accessory subbase must be used
for upright counterflow unit installations over any
combustible material including wood. Refer to
subbase instructions for installation details. Fol-
low the instructions with the subbase for proper
installation. Do not install the furnace directly
on carpeting, tile, or other combustible material
other than wood flooring. (NOTE: The subbase
will not be required if an air conditioning coil is
installed between the supply air opening on the
furnace and the floor.)

Clearances and Accessibility

*MVM97* MINIMUM CLEARANCES TO COMBUSTIBLE MATERIALS
POSITION* FRONT SIDES
Upflow 3" 0"
Horizontal Alcove 6"
C = If placed on combustible floor, floor MUST be wood only.
NOTES:
• For servicing or cleaning, a 24" front clearance is
required.
• Unit connections (electrical, flue and drain) may
necessitate greater clearances than the minimum
clearances listed above.
• In all cases, accessibility clearance must take pre-
cedence over clearances from the enclosure where
accessibility clearances are greater.
