Condensate Drain Instructions

The following sections give general instructions for the
installation of the gas furnace condensate drains.
Repositioning of the condensate trap is covered in the
exhaust air options section.
Cutouts with plugs and grommets are provided on the
left and right hand side of the furnace cabinets for drain
connections IN VERTICAL APPLICATIONS. The
standard arrangement is for the drain connection on
the left side. The tubing may have to be trimmed in this
application to avoid kinking.
The u u p p f f l l o o w w ( ( v v e e r r t t i i c c a a l l a a p p p p l l i i c c a a t t i i o o n n ) ) also has provisions
for right side drain connections. Exchange the
grommet and plugs from the left and right side. Trim
all excess tubing to avoid kinking.
It is always recommended that an auxiliary drain pan
be installed under a horizontally installed evaporator or
90% Gas Furnace. Connect the auxiliary drain line to a
separate drain line (no trap is needed in this line).

N N o o t t e e : : All condensate drain piping supplies included
with the furnace are intended for internal piping
only and should not be applied external to the
furnace. All external piping must use 1/2"
minimum size PVC pipe and fittings throughout
for drain connections (fittings, pipe and PVC
solvent cement not provided with furnace, must
be field supplied). A 3/4" coupling is supplied to
connect to systems that are using 3/4" piping
with an air conditioner coil.
N N o o t t e e : : A corrosion resistant condensate pump must be
used if a pump is required for a specific drain
system.

I I m m p p o o r r t t a a n n t t : : 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 and/ or
its surrounding ambient temperature is
expected to fall below freezing, 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 PlusTM 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.
Evaporator and Furnace condensate drain piping may
be manifolded together. A primary drain vent stack
must be installed and terminated below the outlet of
the secondary heat exchanger drain connection to
prevent water from damaging Furnace controls if the
primary drain outlet plugs up.
