Masonry Chimney Requirement
NOTE:
These furnaces are CSA design-certified for use in exterior
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.
If a clay tile-lined masonry chimney is being used and it is exposed to
the outdoors below the roof line, relining might be required. Chimneys
shall conform to the Standard for Chimneys, Fireplaces, Vents, and Solid
Fuel Burning Appliances ANSI/NFPA 211 in the United States 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 or the authority having jurisdiction to determine whether relining
is required. If relining is required, use a properly sized listed metal liner,
Type-B vent, or a listed alternative venting design.
NOTE:
See the NFPA 54/ANSI Z223.1 13.1.9 and 13.2.20 regarding
alternative venting design and the exception, which cover installations
such as our Chimney Adapter Kits which are listed for use with these
furnaces. See Product Data Sheet for accessory listing.
The Chimney Adapter Kit is a listed alternative venting system for these
furnaces. See the kit instructions for complete details.
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
3. The combined appliance input rating is less than the maximum
, and
4. The input rating of each space heating appliance is greater than the
minimum input rating given in
Design Temperature. Chimneys having internal areas greater than
38 sq. in. (24516 sq. mm) require furnace input ratings greater than
the input ratings of these furnaces. See footnote at bottom of
, and
5. The authority having jurisdiction approves.
*The 99.6% heating (db) temperatures found in the 1997 or 2001 ASHRAE Fundamentals
Handbook, Climatic Design Information chapter,
A (United States) and 2A (Canada)
or the 2005 ASHRAE Fundamentals handbook, Climatic Design Information chapter, and the
CD-ROM included with the 2005 ASHRAE Fundamentals Handbook.
If all of these conditions cannot be met, an alternative venting design
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 common
vent.
Inspections before the sale and at the time of installation will determine
the acceptability of the chimney or the need for repair and/or (re)lining.
to perform a chimney inspection. If the inspection of
a previously used tile-lined chimney:
a. Shows signs of vent gas condensation, the chimney should be
relined in accordance with local codes and the authority having
jurisdiction. The chimney should be relined with a listed metal
liner, Type-B vent, or a listed chimney adapter kit shall be used to
reduce condensation. If a condensate drain is required by local
code, refer to the NFPA 54/ANSI Z223.1, Section 12.10 for
additional information on condensate drains.
