A return air duet system is recommended.
Where there is no complete return air duct
system, a return connection should be run
full size to a location outside the confined
space and completely sealed so that no air
from the confined space can be circulated
through the heating duct system.
EXISTING FURNACE REMOVAL
NOTE: When an existing furnace is
removed from a venting system serving
other appliances, the venting system may be
too large to properly vent the remaining
attached appliances.
If
this furnace is to be installed in the same
space with other oil fired appliances, such
as a water heater, ensure there is an
adequate supply
of
combustion and
ventilation air
for
the other appliances.

! WARNING
UPON COMPLETION OF THE
FURNACE INSTALLATION,
CAREFULLY INSPECT THE
ENTIRE FLUE SYSTEM BOTH
INSIDE AND OUTSIDE OF THE
FURNACE TO ASSURE IT IS
PROPERLY SEALED. LEAKS
IN
THE FLUE SYSTEM CAN RESULT
IN
SERIOUS PERSONAL INJURY
OR DEATH DUE TO EXPOSURE
TO FLUE PRODUCTS, INCLUDING
CARBON MONOXIDE.
A condensing oil 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. Because
of
the
relatively low flue gas temperature and
water condensation requirements, PVC pipe
is used as venting material. This furnace
must not be connected to Type
B,
BW,
or
L
vent
or
vent connector, and must not be
vented into any portion
of
a factory built or
masonry chimney, except when used as a
pathway for PVC as descried later in this
section. Never common vent this appliance
with another appliance
or
use a vent which
is used by a solid fuel appliance.
Do not use commercially available "no hub
connector" other than those shipped with
this
prodUCt.
It is the responsibility
of
the installer to follow
the manufacturers' recommendations and to
verify that all vent/flue piping and connectors
are compatible with furnace flue products.
Additionally, it is the responsibility
of
the
installer to ensure that all piping and
connections possess adequate structural
integrity and support to prevent flue pipe
separation, shifting,
or
sagging during
furnace operation.

Three-inch nominal diameter PVC Schedule
40 pipe meeting ASTM 01785, PVC primer
meeting ASTM F6566, and PVC solvent
cement meeting ASTM
02564
specifications
must be used. Fittings must be OWV type
fittings meeting ASTM
02665
and ASTM
03311. Carefully follow the manufacturer's
instructions
for
cutting, cleaning, and solvent
cementing
of
PVC.
As
an alternative to PVC pipe, primer,
solvent cement, and fittings, ABS materials
which are in compliance with the following
specifications may be used. Three-inch
ABS
Schedule
40
pipe must meet ASTM
01527
and,
if
used in Canada, must
be
CSA
listed solvent cement for ABS to PVC
transition joint must meet ASTM
02235
and,
if
used in Canada must be CSA listed. The
solvent cement for the PVC to ABS
transition joint must meet ASTM 03138.
Fittings must be OWV type fittings meeting
ASTM
02661
and ASTM 03311 and,
if
used in Canada, must be CSA listed.
CarefUlly follow the pipe manufacturers'
instructions
for
cutting, cleaning, and solvent
cementing PVC and/or ABS.
All 90 elbows must be medium radius (1/4
bend OWV)
or
long radius (Long sweep %
bend OWV) types conforming to ASTM
03311. A medium radius (1/4 bend OWV)
elbow measures 4-9/16 minimum from the
plane
of
one opening to the centerline
of
the
other opening
for
3" diameter pipe.
