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, ANSI Z223.1/NFPA 54 or CSA B149.1,
Natural Gas and Propane Installation Code 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, ANSI

Z223.1/NFPA 54 and/or CSA B149.1, Natural Gas
and Propane Installation Code.

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.

WARNING

Vent system or vent connectors may need to be resized. Vent

systems or vent connectors, must be sized to approach minimum
size as determined using appropriate table found in the NFGC or

CAN/CSA--B149.1--05.
GENERAL VENTING REQUIREMENTS
Follow all safety codes for proper vent sizing and installation
requirements, including local building codes, the National Fuel

Gas Code ANSI Z223.1--2006/NFPA 54--2006 (NFGC), Parts 12
and 13 in the United States or the National Standard of Canada,

Natural Gas and Propane Installation Code CSA--B149.1--05

(CAN/CSA--B149.1--05), Section 8 and Appendix C in Canada,

the local building codes, and furnace and vent manufacturers’
instructions.

These furnaces are design--certified as Category I furnaces in

accordance with ANSI Z21.47--2006/CSA 2.3--2006 and operate

with a non--positive vent static pressure to minimize the potential

for vent gas leakage. Category I furnaces operate with a flue loss
not less than 17 percent to minimize the potential for

condensation in the venting system. These furnaces are approved
for common venting and multistory venting with other fan

assisted or draft hood equipped appliances in accordance with the

NFGC or the CAN/CSA--B149.1--05, the local building codes,
and furnace and vent manufacturers’ instructions. The following

information and warning must be considered in addition to the
requirements

defined

in

the

NFGC

and

the

CAN/CSA--B149.1--05.

1. If a vent (common or dedicated) becomes blocked, the

furnace will be shut off by the draft safeguard switch
located on the vent elbow.

2. Do not vent this Category I furnace into a single--wall

dedicated or common vent. The dedicated or common

vent is considered to be the vertical portion of the vent
system that terminates outdoors.

3. Vent connectors serving Category I furnaces shall not be

connected into any portion of a mechanical draft system
operating under positive pressure.

4. In the U.S.: Do not vent this appliance with any solid fuel

burning appliance. In Canada: Check with the authority
having jurisdiction for approval on use with solid fuel

burning appliance.

5. Category I furnaces must be vented vertically or nearly

vertically unless equipped with a listed power ventor.

6. Do not vent this appliance into an unlined masonry

chimney. Refer to Chimney Inspection Chart, Fig. 33.

MASONRY CHIMNEY REQUIREMENTS
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 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--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 NFGC

NFPA54/ANSI Z223.1--2006 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 NFPA54/ANSI 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
KGACA02014FC and KGACA02015FC, 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.
