MASONRY CHIMNEY REQUIREMENTS
NOTE:
These furnaces are CSA design-certified
for use in
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
numbers 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
211-2009
and must
be in good
condition.
U.S.A.-Refer
to N FPA 54/ANSI Z223.1-2009
Sections 13.1.8
and 13.2.20 of the NFGC 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 Z223.1-2009,
13.1.8 and
13.2.20
regarding
alternative
venting
design
and
the
Exception,
which cover installations
such as the Chimney
Adapter Kits, which are listed for use with these furnaces.
The Chimney Adapter Kit is 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 capacity given in Table 8, and
4. The input rating of each space heating appliance
is
greater than the minimum input rating given in Table 9
for the local 99% Winter Design Temperature.
Chim-
neys having internal areas greater than 38 in2 (24516
mm 2) require furnace input ratings greater than the in-
put ratings of these furnaces. See footnote at bottom of
Table 9, and
5. The authority having jurisdiction approves.
If all of these conditions cannot be met, an alternative venting
design shall be used, such as the listed chimney adapter kit
with these furnaces,
which are 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. Refer to the Chimney Inspection Chart
to perform
a chimney
inspection.
If the inspection
of a
previously used tile-lined
chimney:
a. Shows signs of vent gas condensation, the chim-
ney 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 Z223.1-2009,
Section 12.10 for additional
information on condensate drains.
b. Indicates the chimney exceeds the maximum per-
missible size in the tables, the chimney should be
rebuilt or relined to conform to the requirements of
the equipment being installed and the authority hav-
ing jurisdiction.
A chimney without a clay tile liner, which is otherwise in good
condition, shall be rebuilt to conform to ANSI/NFPA 211 or be
lined with a UL listed metal liner or UL listed Type-B vent.
Relining with a listed metal liner or Type-B vent is considered
to be a vent-in-a-chase.
If a metal liner or Type-B vent is used to line a chimney, no
other
appliance
shall
be vented
into the annular
space
between the chimney and the metal liner.
