7. Masonry Chimney Venting
Chimney Inspection
All masonry chimney construction must conform to Standard
NFPA 211-2006 and to any state or local codes applicable. The
chimney must be in good condition and a complete chimney in-
spection must be conducted prior to furnace installation. If the in-
spection reveals damage or abnormal conditions, make
necessary repairs or seek expert help. See "The Chimney Inspec-
tion Chart" Figure 11. Measure inside area of tile-liner and exact
height of chimney from the top of the chimney to the highest ap-
pliance flue collar or drafthood outlet.
Connector Type
To reduce flue gas heat loss and the chance of condensate prob-
lems, the vent connector must be double-wall Type B vent except
as specified in the listed kit.
Venting Restrictions for Chimney Types
Interior Chimney - has no sides exposed to the outdoors below
the roofiine. All installations can be single furnace or common
vented with another draft hood equipped Category [ appliance.
If a clay tile-lined masonry chimney is being used and it is ex-
posed to the outdoors below the roof line, relining might be re-
quired. Chimneys shall conform to the Standard for Chimneys,
Fireplaces, Vents, and Solid Fuel Burning Appliances NFPA
211-2006 in the United States and to a Provincial or Territorial
Building Code in Canada (in its absence, the National Building
Code of Canada) and must be in good condition.
U.S.A.-Refer to Sections 13.1.8 and 13.2.20 of the NFPA
54/ANSI Z223.1-2006 orthe authority having jurisdiction to deter-
mine whether relining is required. If relining is required, use a
properly sized listed metal liner, Type-B vent, or a listed alterna-
tive venting design.
NOTE: See the N FPA 54/AN SI Z223.1-2006, 13.1.8 and 13.2.20
regarding alternative venting design and the exception, which
cover installations such as the Chimney Adapter Kits
NAHA001DH and NAHA002DH, which are listed for use with
these furnaces.
The Chimney Adapter Kit are listed alternative venting design for
these furnaces. See the kit instructions for complete details.
Exterior Chimney - has one or more sides exposed to the out-
doors below the roof line. All installations with a 99% Winter De-
sign Temperature* below 17°F (-8°C) must be common vented
only with a draft hood equipped Category ! appliance.
* The 99% Winter Design Dry-Bulb (db) temperatures are
found in the 2005 ASHRAE Fundamentals Handbook CD
and Chapter 28.
Canada (and U.S.A.)-This furnace is permitted to be vented into
a clay tile-lined masonry chimney that is exposed to the outdoors
below the roof line, provided:
1. Vent connector is Type-B double-wall, and
2. This furnace is common vented with at least 1 draft hood-
equipped appliance, and
CARBON MONOXIDE POISONING, FIRE AND
EXPLOSION HAZARD
Failure to properly vent this furnace could result in
personal injury, death and/or property damage.
These furnaces are CSA (formerly AGA and CGA)
design-certified for venting into exterior clay
tile-lined masonry chimneys with a factory
accessory Chimney Adapter Kit. Refer to the
furnace rating plate for correct kit usage. The
Chimney Adapter Kits are for use with ONLY
furnaces having a Chimney Adapter Kit number
marked on the furnace rating plate.

The combined appliance input rating is less than the maxi-
mum capacity given in Table A, and
The input rating of each space-heating appliance is greater
than the minimum input rating given in Table B for Masonry
Chimneys for the local 99% Winter Design Temperature.
Chimneys having internal areas greater than 38 square
inches require furnace input ratings greater than the input
ratings of these furnaces. See footnote at bottom of Table
B, and
5. The authority having jurisdiction approves.
If all of these conditions cannot be met, an alternative venting de-
sign shall be used, such as the listed chimney adapter kit with a
furnace listed for use with the kit, a listed chimney-lining system,
or a Type-B vent.
