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 the CSA B149.1, Natural Gas and
Propane Installation Codes and these instructions. Deter-
mine 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 appli-
ance 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
Codes.
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 appli-
ance to their previous conditions of use.
Vent system or vent connectors may need to be resized. For any
other appliances when resizing vent systems or vent connectors,
system or connector must be sized to approach minimum size as
determined using appropriate table found in the NFGC or NSC-
NGPIC.
GENERAL VENTING REQUIREMENTS
Follow all safety codes for proper vent sizing and installation
requirements, including local building codes, the National Fuel
Gas Code (NFGC) ANSI Z223.1-2002/NFPA 54-2002, Parts 7 and
13 in the United States or the National Standard of Canada, Natural
Gas and Propane Installation Code (NSCNGPIC) CSA-B149.1-00,
Section 7 and Appendix C in Canada.
These furnaces are design-certified as Category I furnaces in
accordance with ANSI Z21.47/CSA 2.3-2001 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 multi-story venting with other fan assisted or draft hood
equipped appliances in accordance with the NFCG or the NSC-
NGPIC.
The following information and warning must be considered in
addition to the requirements defined in the NFGC and the
NSCNGPIC.
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.
Do not bypass the draft safeguard switch, as an unsafe
condition could exist which must be corrected. Failure to
follow this warning could result in a build-up of carbon
monoxide and lead to personal injury or death.
2. Do not connect this appliance to 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 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.
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. 25.
MASONRY CHIMNEY REQUIREMENTS
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 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 Soild Fuel Burning Appliances ANSI/NFPA 211-2000
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.
