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
CONNECTION MUST BE MADE AT THE
FURNACE VENT EXIT.
It must originate
with an adapter if required, at the furnace
flue collar and terminate either in a listed
cap or roof assembly. When common
venting, the vent connector size may differ
from the above diameters depending on
application. See ANSI Z21.47-
1993/CAN/CGA-2.3-M93 or latest edition
tables.
VERTICAL VENT SYSTEMS:
1. Terminate a gas vent 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 10,
provided they are at least 8 feet from
a vertical wall or similar obstruction.
Terminate all other gas vents 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. Terminate a type B gas vent at least
5 feet in vertical height above the
highest connected equipment draft
hood or flue collar.
DO NOT CONNECT THIS FURNACE
TO A CHIMNEY USED TO VENT A
SOLID FUEL APPLIANCE (WOOD
OR COAL). VENTING WITH A SOLID
FUEL APPLIANCE CAN LEAD TO
IMPROPER FUNCTIONING OF THE
UNIT, AND DUE TO SOOTING, THE
POSSIBILITY OF FIRE RESULTING
IN PROPERTY DAMAGE,
PERSONAL INJURY OR DEATH.
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. Mechanically fasten the vent
connector to the outlet collar of the
furnace with at least (2) sheet metal
screws except vent connectors that
are B-1 material. Assemble these
assembled in accordance with the
manufacturer’s instructions. See
Figure 9.
NOTE: Refer to the National Fuel Gas
Code, ANSI Z223.1 and/or the Natural
Gas Installation Code, CAN/CGA-
B149.1 & .2.
Single appliance venting of a fan
assisted furnace into a tile-lined
masonry chimney is prohibited. Line
the chimney 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, CAN/CGA-
B149.1 & .2. See Figure 11 for typical
B-1 vent chase.
