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 Specification Sheet for accessory listing.

Fig. 33 – Chimney Inspection Chart
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
capacity given in Table 6, and
4. The input rating of each space heating appliance is greater than the
minimum input rating given in Table 6 for the local 99% Winter
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
Table 6, 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 a furnace listed
for use with the kit, a listed chimney-lining system, or a Type-B common
vent.
WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each appliance connected
to the venting system being placed into operation could result in carbon
monoxide poisoning or death.
The following steps shall be followed for each appliance connected to
the venting system being placed into operation, while all other
appliances connected to the venting system are not in operation:
1. Seal any unused openings in venting system.
2. Inspect the venting system for proper size and horizontal pitch, as
required in the National Fuel Gas Code, NFPA 54/ANSI Z223.1
and these instructions. Determine that there is no blockage or
restriction, leakage, corrosion and other deficiencies, which could
cause an unsafe condition.
3. As far as practical, close all building doors and windows and all
doors between the space in which the appliance(s) connected to
the venting system are located and other spaces of the building.
4. Close fireplace dampers.
5. Turn on clothes dryers and any appliance not connected to the
venting system. Turn on any exhaust fans, such as range hoods and
bathroom exhausts, so they are operating at maximum speed. Do
not operate a summer exhaust fan.
6. Follow the lighting instructions. Place the appliance being
inspected into operation. Adjust the thermostat so appliance is
operating continuously.
7. Test for spillage from draft hood equipped appliances at the draft
hood relief opening after 5 minutes of main burner operation. Use
the flame of a match or candle.
8. If improper venting is observed during any of the above tests, the
venting system must be corrected in accordance with the National
Fuel Gas Code, NFPA 54/ANSI Z223.1.
9. After it has been determined that each appliance connected to the
venting system properly vents when tested as outlined above,
return doors, windows, exhaust fans, fireplace dampers and any
other gas-fired burning appliance to their previous conditions of
use.
