*NOTE: All furnaces have a 3” vent connec-
tion as shipped from the factory. A 3” to 4” or
3” to 5” vent transition is required on all but
the 50,000 BTUH models when vertically
vented or common vented with metal vent
pipes. THE VENT TRANSITION CONNEC-
TION MUST BE MADE AT THE FURNACE
VENT EXIT. It must originate with an adapter
if required, at the furnace flue collar and ter-
minate either in a listed cap or roof assem-
bly. When common venting, the vent con-
nector size may differ from the above diame-
ters depending on application. See ANSI
Z21.47-1993/CSA-2.3-M93 or latest edition
tables.
VERTICAL VENT SYSTEMS:
1. A gas vent shall terminate above the
roof surface with a listed cap or listed
roof assembly. Gas vents 12 inches
in size or smaller with listed caps
shall be permitted to be terminated in
accordance with Figure 13, provided
they are at least 8 feet from a vertical
wall or similar obstruction. All other
gas vents shall terminate not less
than 2 feet above the highest point
where they pass through the roof and
at least 2 feet higher than any portion
of a building within 10 feet.
2. A type B-1 gas vent shall terminate
at least 5 feet in vertical height above
the highest connected equipment
draft hood or flue collar.
3. Must rise 1 /
4
” per foot away from the
furnace on horizontal runs and be
supported with straps or hangers so
it has no sags or dips. Supports at 4
foot intervals and at all elbows are
recommended.
4. The vent connector must be mechan-
ically fastened to the outlet collar of
the furnace with at least (2) sheet
metal screws except vent connectors
that are B-1 material. These shall be
assembled in accordance with the
manufacturer’s instructions. See
Figure 12.
DO NOT CONNECT THIS FUR-
NACE TO A CHIMNEY USED TO
VENT A SOLID FUEL APPLIANCE
(WOOD OR COAL). VENTING
WITH A SOLID FUEL APPLIANCE
CAN LEAD TO IMPROPER FUNC-
TIONING OF THE UNIT, AND DUE
TO SOOTING, THE POSSIBILITY
OF FIRE RESULTING IN PROPER-
TY DAMAGE, PERSONAL INJURY
OR DEATH.

IMPORTANT: It is THE FURNACE
MANUFACTURER’s position now
that new installations of any HTPV
pipe used in a category
III vent
application, including Selkirk’s
Selvent™
II HTPV product, should
cease immediately.
5. Any angle greater than 45 degrees
from the vertical is considered hori-
zontal. The total horizontal distance
of a vent plus the horizontal vent
connector serving draft-hood
equipped appliances shall not be
greater than 75 percent of the verti-
cal height of the vent.
NOTE: Refer to the National Fuel Gas
Code, ANSI Z223.1 and/or the Natural
Gas Installation Code,
CSA-B149.1 & .2.
Single appliance venting of a fan assist-
ed furnace into a tile-lined masonry
chimney is prohibited. The chimney
must be lined with either Type B vent or
with a listed, single wall, metal lining
system. Reference National Fuel Gas
Code, ANSI Z223.1 and/or the Natural
Gas Installation Code, CSA-B149.1 &
.2. See Figure 14 for typical B-1 vent
chase.
