Installed in Combination with a Cooling Coil
When this furnace is used with cooling units, it shall be
installed in parallel with, or on the upstream side of, cooling
units to avoid condensation in the heating compartment.
With a parallel flow arrangement, a damper (or other
means to control the flow of air) must adequately prevent
chilled air from entering the furnace (see Figure 2). If the
damper is manually operated, it must be equipped to
prevent operation of either the heating or the cooling unit,
unless it is in the full HEAT or COOL setting.

UNLESS ALL OF THE FOLLOWING CRITERIA ARE
MET:
a.
Furnace must be in its final location. The vent system
must be permanently installed per these installation
instructions.
b.

sealed to the furnace. Return air must be terminated
outside of the space where furnace is installed.
f.
Return air temperature range between 60°F (16°C)
and 80°F (27°C) must be maintained.
g.
MERV 11 or greater air filters must be installed in
the system and must be regularly inspected and
maintained (e.g., regular static checks and replaced at
end of life) during construction.
h.
Blower and vestibule access panels must be in place
on the furnace at all times.
i.
The furnace heat exchanger, components, duct
system, and evaporator coils must be thoroughly
cleaned following final construction clean−up.
j.

completion.
k.
All furnace operating conditions (including ignition,
input rate, temperature rise and venting) must
be verified in accordance with these installation
instructions.
