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.

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

13.2.20regarding 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.
