42OPTIONAL VENTING BELOW THE FURNACEThe venting system may be positioned below the furnaceONLY IF the factory accessory External Vent Trap Kit is used.The External Vent Trap Kit is only approved for PVC/ABSDWV venting systems.CAREFULLY FOLLOW THE INSTRUCTIONSPROVIDED WITH THE EXTERNAL VENT TRAP KITFOR LAYING OUT THE VENTING SYSTEM ANDTHE DRAIN SYSTEM. The instructions included with thisfurnace DO NOT APPLY to vent systems that are locatedbelow the furnace.NOTICECARBON MONOXIDE POISONING HAZARDFailure to follow the instructions outlined below for eachappliance being placed into operation could result in carbonmonoxide poisoning or death.The instructions included with this furnace DO NOT APPLYto vent systems that are located below the furnace.CAREFULLY FOLLOW THE INSTRUCTIONSPROVIDED WITH THE EXTERNAL VENT TRAP KITFOR LAYING OUT THE VENTING SYSTEM ANDTHE DRAIN SYSTEM when all or part of the ventingsystem is placed below the furnace.Proper configuration of the venting and drain system is criticalwhen placing all or part of the venting system below the levelof the furnace. VENT GASSES COULD BE RELEASEDFROM THE DRAINAGE SYSTEM if the instructionsprovided with the External Vent Trap Kit are not followed.! WARNINGLocating the Vent TerminationGeneralNOTE: Termination Requirements for the Provinces ofAlberta and Saskatchewan are located at the end of thissection.Combustion--air inlet pipe (direct vent/2--pipe system only) andvent pipe must terminate outside structure, either through sidewallor roof.Special termination requirements may be required in otherCanadian provinces. Refer to the authority having jurisdiction forclarification and/or additional clearance requirements.For vent termination clearance, references to National codes are shownin Fig. 52 for Direct Vent/2--Pipe system and Fig. 53 for VentilatedCombustion Air/Non--direct Vent/1--Pipe system. For exteriortermination arrangements, refer to Fig. 54 for Direct Vent/2--Pipesystem and Fig. 55 for Ventilated Combustion Air/Non--Direct/1--Pipesystem. Contact Local code authorities for other requirements toand/or exemptions from the National codes shown in the figures.Roof termination is often preferred since it is less susceptible todamage or contamination, is usually located away from adjacentstructures, is less prone to icing conditions, and and it often has lessvisible vent vapors. Sidewall terminations may require sealing orshielding of building surfaces with a corrosive resistance material dueto the corrosive properties of combustion products from the ventsystem, as well as protection of adjacent structures.Roof termination is the recommended termination location. Roofterminations provide better performance against sustained prevailingwinds. The roof location is preferred since the vent and combustionair system is less susceptible to damage or contamination. Thetermination is usually located away from adjacent structures or otherobstacles such as inside corners, windows, doors or other appliances. Itis less prone to icing conditions, and it often has less visible ventvapors.Sidewall terminations may require sealing or shielding of buildingsurfaces with a corrosive resistance material due to the corrosiveproperties of combustion products from the vent system, as well asprotection of adjacent structures.RECOMMENDED SUPPORT FORVENT TERMINATIONSIt is recommended that sidewall vent terminations in excess of24 inches (0.6 M) or rooftop terminations in excess of 36inches (1 M) in vertical length be supported by EITHER theDirect Vent Termination Kit shown in Table 12 or byfield--supplied brackets or supports fastened to the structure.NOTICEWhen determining appropriate location for termination, considerthe following guidelines:1. Comply with all clearance requirements stated in Fig. 52 orFig. 53 per application.2. The vent termination must be located at least 3 feet from aninside corner and follow the clearance distances in the In-side Corner Termination drawing.3. Termination or termination kit should be positioned wherevent vapors will not damage plants/shrubs, air conditioningequipment or utility meters.4. Do not locate termination directly into prevailing winds.Termination should be positioned so that it will not beaffected by sustained prevailing winds over 30 mph, windeddy, such as inside building corners, or by recirculation offlue gases, airborne leaves, or light snow.5. Termination or termination kit should be positioned where itwill not be damaged by or subjected to foreign objects suchas stones, balls, etc.6. Termination or termination kit should be positioned wherevent vapors are not objectionable.Direct Vent / 2-Pipe SystemDirect vent (2--pipe) vent and combustion air pipes must terminateoutside the structure. See Fig. 52 For references to vent clearancesrequired by National code authorities. Allowable vent andcombustion air terminations are shown in Fig. 54.CARBON MONOXIDE POISONING HAZARDFailure to follow the instructions outlined below for eachappliance being placed into operation could result in carbonmonoxide poisoning or death.For all venting configurations for this appliance and other gasappliances placed into operation for the structure, provisionsfor adequate combustion, ventilation, and dilution air must beprovided in accordance with:U.S.A. Installations: Current edition of Section 9.3 NFPA54/ANSI Z223.1 Air for Combustion and Ventilation andapplicable provisions of the local building codes.Canadian Installations: Current edition of Part 8 ofCAN/CSA--B149.1. Venting Systems and Air Supply forAppliances and all authorities having jurisdiction.! WARNINGVentilated Combustion AirThe vent pipe for a Ventilated Combustion Air System mustterminate outdoors. See Fig. 53 for references to vent clearances
