CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal
injury or death.
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 the 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 10
and 13 in the United States or the National Standard of Canada,
Natural Gas and Propane Installation Code CSA--B149.1--00
(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--2003/CSA 2.3--2003 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% to minimize the potential for condensation in
the venting system. These furnaces are approved for common
venting and multi--story venting with other fan assisted or draft
hood equipped appliances in accordance with the NFCG or the
CAN/CSA--B149.1--05, 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 or the
CAN/CSA--B149.1--05.
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal
injury or death.
Do not bypass the draft safeguard switch, as an unsafe
condition could exist which must be corrected.
! WARNING
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. Two--stage furnaces require Type B vent connectors
outside the casing in all configurations. Single wall vent
connector may be used inside the furnace casing with the
transition to Type B vent outside the furnace casing. Size
the connector so that the FAN--Min vent connector
capacity is equal to or lower than the low fire rate of the
furnace and the FAN--Max vent connector capacity is
equal to or higher than the furnace high fire rate.
3. 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.
4. Vent connectors serving Category I furnaces shall not be
connected into any portion of a mechanical draft system
operating under positive pressure.
5. In the US: 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.
6. Category I furnaces must be vented vertically or nearly
vertically unless equipped with a listed mechanical venter.
See the SIDEWALL VENTING section.
7. Do not vent this appliance into an unlined masonry
chimney. Refer to Chimney Inspection Chart, Fig. 35.
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 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--2003 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 13.1.9 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 NFGC, 13.1.9 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.
