WARNING
Materials
PVC, CPVC, or ABS pipe & fittings are typically used as
venting and intake pipe materials. All 90° elbows must be
medium or long radius types. A medium radius elbow should
measure ~3-1/16” minimum from the plane of one opening
to the center line of the other opening for 2” diameter pipe,
and ~4-9/16” minimum for 3” pipe.
In addition to these materials, Innoflue® by Centrotherm
Eco Systems and PolyPro® by M&G Duravent are also ap
-
proved vent and combustion air materials for installations in
the U.S.A. Manufacturers Installation instructions for these
products must be followed. These products have specific
instructions for installing, joining and terminating. Do not mix
materials or components of one manufacturer with materials
or components of another manufacturer. Refer to the follow
-
ing chart for plastic pipe & fittings specifications
Drain Trap and Lines
In horizontal applications the condensate drain trap is secured
to the furnace side panel, suspending it below the furnace. A
minimum clearance of 5.5” below the furnace must be provided
for the drain trap. Additionally, the appropriate downward
piping slope must be maintained from the drain trap to the
drain location. Refer to
Condensate Drain Trap and Lines
for
further details. If the drain trap and drain line will be exposed
to temperatures near or below freezing, adequate measures
must be taken to prevent condensate from freezing.
Leveling
Leveling ensures proper condensate drainage from the heat ex
-
changer. For proper flue pipe drainage, the furnace must be
level lengthwise from end to end. The furnace should have
a slight tilt from back to front with the access doors downhill
from the back panel approximately 1/2” to 3/4”. The slight tilt
allows the heat exchanger condensate, generated in the recu
-
perator coil, to flow forward to the recuperator coil front cover.
Alternate Electrical and Gas Line Connections
This furnace has provisions allowing for electrical and gas line
connections through either side panel. In horizontal applications
the connections can be made either through the “top” or “bottom”
of the furnace.
Drain Pan
A drain pan must be provided if the furnace is installed above a
conditioned area. The drain pan must cover the entire area under
the furnace (and air conditioning coil if applicable).
Freeze Protection
Refer to
Horizontal Applications and Conditions - Drain Trap
and Lines.
Vent Pipe & Combustion Air Pipe
This manual will refer to the pipe that discharges products of
combustion to the outdoors as the “vent” pipe or “flue” pipe.
The pipe that supplies air for combustion to the furnace will
be referred to as the “intake” pipe or “combustion air” pipe.
This furnace is dual certified and may be installed as a non-di
-
rect vent (single pipe) or direct vent (dual pipe) appliance.
