3. At the front-to-back of duct run (Area “A”),
bend the duct tabs and secure them directly
to the duct.
4. At Area “B”, bend the duct tabs up and back
over, around the duct connector, (See
Step 3).
5. Fold/form the duct flap against the side of the
duct connector and attach as shown, (See
Step 4). Use three (3) staples (minimum) on
each duct flap OR, if a 2X block/joist is not
provided, use two (2) sheet metal screws
(minimum) on each duct flap. An alternate
attachment method is acceptable, as long
as the plenum is securely attached.
6. Tape the duct flap edges with an approved
tape for a leak-free joint.

VENTING AND COMBUSTION AIR
REQUIREMENTS
!
CAUTION:
Snow must not be allowed to restrict or
block the combustion air intake or vent
pipes.
General
NORDYNE condensing furnaces must be
installed with outdoor combustion air piped
directly to the furnace. Codes refer to this
type of installation as direct vent, or two pipe
installation.
Provisions must be made for adequate supply
of air for combustion and ventilation. For
United States installations, the adequacy of
air provisions can be determined by consulting
the current version of the National Fuel Gas
Code (ANSI Z223.1/NPFA-54). For Canadian
installations, requirements are specified in the
National Standard of Canada (CAN/CGA
B149.1 & .2). Consult local codes for special
requirements.
NOTE: If the furnace is operated without
adequate air for combustion and ventilation, it
may not perform properly. Furnace
components may be strained by high
temperature and could fail prematurely.
!
WARNING:
The combustion air piping must not be
blocked or restricted in any manner.
!
WARNING:
Furnace installation using methods
other than those described in the
following sections must comply with the
National Fuel Gas Code and all
applicable local codes to provide
sufficient combustion air for the furnace.
