26CARBON MONOXIDE POISONING HAZARDFailure to follow the steps outlined below for eachappliance connected to the venting system being placed intooperation could result in carbon monoxide poisoning ordeath. The following steps shall be followed for eachappliance connected to the venting system being placed intooperation, while all other appliances connected to theventing system are not in operation:1. Seal any unused openings in venting system.2. Inspect the venting system for proper size andhorizontal pitch, as required in the National Fuel GasCode, ANSI Z223.1/NFPA 54 and theseinstructions. Determine that there is no blockage orrestriction, leakage, corrosion and other deficiencies,which could cause an unsafe condition.3. As far as practical, close all building doors andwindows and all doors between the space in whichthe appliance(s) connected to the venting system arelocated and other spaces of the building.4. Close fireplace dampers.5. Turn on clothes dryers and any appliance notconnected to the venting system. Turn on anyexhaust fans, such as range hoods and bathroomexhausts, so they are operating at maximum speed.Do not operate a summer exhaust fan.6. Follow the lighting instructions. Place the appliancebeing inspected into operation. Adjust the thermostatso appliance is operating continuously.7. Test for spillage from draft hood equippedappliances at the draft hood relief opening after 5minutes of main burner operation. Use the flame of amatch or candle.8. If improper venting is observed during any of theabove tests, the venting system must be corrected inaccordance with the National Fuel Gas Code, ANSIZ223.1/NFPA 54.9. After it has been determined that each applianceconnected to the venting system properly vents whentested as outlined above, return doors, windows,exhaust fans, fireplace dampers and any othergas--fired burning appliance to their previousconditions of use.! WARNINGVent system or vent connectors may need to be resized. Ventsystems or vent connectors must be sized to approach minimumsize as determined using appropriate table found in the NFGC.GENERAL VENTING REQUIREMENTSFollow all safety codes for proper vent sizing and installationrequirements, including local building codes, the National FuelGas Code ANSI Z223.1--2012/NFPA 54--2012 (NFGC), Parts 12and 13 in the United States, the local building codes, and furnaceand vent manufacturers’ instructions.These furnaces are design--certified as Category I furnaces inaccordance with ANSI Z21.47--2012/CSA 2.3--2012 and operatewith a non--positive vent static pressure to minimize the potentialfor vent gas leakage. Category I furnaces operate with a flue lossnot less than 17% to minimize the potential for condensation inthe venting system. These furnaces are approved for commonventing and multi--story venting with other fan assisted or drafthood equipped appliances in accordance with the NFCG, localbuilding codes, and furnace and vent manufacturers’ instructions.The following information and warning must be considered inaddition to the requirements defined in the NFGC.CARBON MONOXIDE POISONING HAZARDFailure to follow this warning could result in personalinjury or death.Do not bypass the draft safeguard switch, as an unsafecondition could exist which must be corrected.! WARNING1. If a vent (common or dedicated) becomes blocked, the fur-nace will be shut off by the draft safeguard switch locatedon the vent elbow.2. Two--stage furnaces require Type B vent connectors out-side the casing in all configurations. Single wall vent con-nector may be used inside the furnace casing with thetransition to Type B vent outside the furnace casing. Sizethe connector so that the FAN--Min vent connector capa-city is equal to or lower than the low fire rate of the fur-nace and the FAN--Max vent connector capacity is equalto or higher than the furnace high fire rate.3. Do not vent this Category I furnace into a single wall ded-icated or common vent. The dedicated or common vent isconsidered to be the vertical portion of the vent systemthat terminates outdoors.4. Vent connectors serving Category I furnaces shall not beconnected into any portion of a mechanical draft systemoperating under positive pressure.5. Do not vent this appliance with any solid fuel burning ap-pliance.6. Category I furnaces must be vented vertically or nearlyvertically unless equipped with a listed mechanical venter.See the SIDEWALL VENTING section.7. Do not vent this appliance into an unlined masonry chim-ney. Refer to Chimney Inspection Chart, Fig. 34.MASONRY CHIMNEY REQUIREMENTSNOTE: These furnaces are CSA design--certified for use inexterior tile--lined masonry chimneys with a factory accessoryChimney Adapter Kit. Refer to the furnace rating plate for correctkit usage. The Chimney Adapter Kits are for use with ONLYfurnaces having a Chimney Adapter Kit number marked on thefurnace rating plate.If a clay tile--lined masonry chimney is being used and it isexposed to the outdoors below the roof line, relining might berequired. Chimneys shall conform to the Standard for Chimneys,Fireplaces, Vents, and Solid Fuel Burning AppliancesANSI/NFPA 211--2012 in the United States and must be in goodcondition.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 todetermine whether relining is required. If relining is required, usea properly sized listed metal liner, Type--B vent, or a listedalternative venting design.NOTE: See the NFPA 54 / ANSI Z223.1--2012, 13.1.8 and13.2.20 regarding alternative venting design and the exception,which cover installations such as the Chimney Adapter Kitswhich are listed for use with these furnaces.
