VERTICAL DOWNFLOW – LEFT SIDE
CONDENSATE DRAIN CONNECTION
IMPORTANT:
The condensate drain should be installed with provisions to prevent
winter freeze-up of the condensate drain line. Frozen condensate
will block drains, resulting in furnace shutdown. If the drain line
cannot be installed in a conditioned space, then heat tape should be
applied as required to prevent freezing (per manufacturer's
instructions). The heat tape should be rated at 5 or 6 watts per foot
at 120 volts. Self-regulating (preferred) or thermostatically controlled
heat tape is required.
Typical sources of UL listed heat tapes are W.W. Granger, Inc.
(Wintergard Plus™ Series), McMaster Carr Supply Co.
(3554 Series), or your equipment supplier.
The condensate drain may be cleaned or inspected by removal of
the drain tube at the header as shown in the illustrations.

CAUTION
!
If the furnace is to be vented through the wall, the preferred
application is to avoid installation through the wall exposed to
the prevailing winter wind, where possible.
A wall sheltered from the prevailing wind is least likely to
experience excessive wind pressure and possible nuisance
induced draft blower pressure switch trips.
The vent/wind terminal must be located at least 12" minimum
above normally expected snow accumulation level.
Avoid areas where staining or condensate dripping may be a
problem.
