This kit is to be used with 2" or 3" direct vent systems. The vent kit
must terminate outside the structure and may be installed with the
intake and exhaust pipes located side-by-side or with one pipe
above the other. This kit is NOT intended for use with single pipe
(indirect vent) installations.
Refer to the directions furnished with the Side Wall Vent Kit (p/n

X. CONDENSATE DRAIN LINES & DRAIN TRAP
G
ENERAL
A condensing gas furnace achieves its high level of efficiency by
extracting almost all of the heat from the products of combustion
and cooling them to the point where condensation takes place.
The condensate which is generated must be piped to an appropri-
ate drain location.
In upright installations, the furnace's drain hoses may exit either
the right or left side of the furnace. NOTE: If the alternate vent/flue
outlet is utilized in an upright installation, the drain trap and drain
connections must be located on the same side as the alternate
vent/flue outlet.
In horizontal installations, the drain hoses will exit through the
bottom (down side) of the unit with the drain trap suspended be-
neath the furnace. The field-supplied drain system must be in
accordance with all local codes and the instructions in the follow-
ing sections.
Follow the bullets listed below when installing the drain system.
Refer to the following sections for specific details concerning fur-
nace drain trap installation and drain hose hook ups.
• The drain trap supplied with the furnace must be used.
• The drain line between furnace and drain location must
be constructed of 3/4" PVC or CPVC.
• The drain line between furnace and drain location must
maintain a 1/4 inch per foot downward slope toward
the drain.
• Do not trap the drain line in any other location than at
the drain trap supplied with the furnace.
• Do not route the drain line outside where it may freeze.
• If the drain line is routed through an area which may
see temperatures near or below freezing, precautions
must be taken to prevent condensate from freezing
within the drain line.
• If an air conditioning coil is installed with the furnace, a
common drain may be used. An open tee must be
installed in the drain line, near the cooling coil, to
relieve positive air pressure from the coil's plenum.
This is necessary to prohibit any interference with the
function of the furnace's drain trap.

PRIGHT NSTALLATIONS
In an upright installation drain hoses are connected to drain ports
on the rubber elbow and the recuperator coil front cover. The drain
lines are then routed through the right or left side panel and into
the drain trap secured to the outside of the cabinet.
NOTE: Refer to Section X, Condensate Drain Lines and Drain Trap
- Alternate Vent/Flue Hose Connections for upright installations
using an alternate vent/flue outlet.
