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, 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.
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.
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
−
2012/NFPA 54
−
2012 (NFGC),
Parts 12 and 13 in the United States, 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
−
2012/CSA 2.3
−
2012 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, 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.
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. Do not vent this appliance with any 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,
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
−
2012 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
−
2012 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
−
2012, 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 is listed alternative venting system for these
furnaces. See the kit instructions for complete details.
