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.
