59TP5AA furnace shall not be connected to a chimney flue serving aseparate appliance designed to burn solid fuel.Other gas appliances with their own venting system may also usethe abandoned chimney as a raceway providing it is permitted bylocal code, the current edition of the National Fuel Gas Code andthe vent or liner manufacturer’s installation instructions. Care mustbe taken to prevent the exhaust gases from one appliance fromcontaminating the combustion air of other gas appliances.Do not take combustion air from inside the chimney when usingventilated combustion air or single pipe vent option.These furnaces can be vented as either direct vent furnace,ventilated combustion air system or non-direct (single pipe) ventsystem. Each type of venting system is described below. Commonventing between furnaces or other appliances prohibited.MaterialsU.S.A.Combustion air and vent pipe, fittings, primers, and solvents mustconform to American National Standards Institute (ANSI)standards and American Society for Testing and Materials (ASTM)standards. See Table 11 for approved materials for use in theU.S.A.CanadaSpecial Venting Requirements for Installations in CanadaInstallation in Canada must conform to the requirements of CSAB149 code. Vent systems must be composed of pipe, fittings,cements, and primers listed to ULC S636.Venting SystemsA factory accessory KGAVT vent termination kit must be used forall direct vent terminations. Termination kits are available for 2 -in.or 3 -in. pipe. See Table 10 for available options.Table 10 – Vent Termination Kit for Direct Vent (2 -pipe)SystemsDIRECT VENT(2---PIPE)TERMINATION KIT2 --- in. (51 mm)Concentric Vent Kit3 --- in.

Combustion-air and vent pipesmust terminate together in the same atmospheric pressure zone,either through the roof or a sidewall (roof termination preferred). Afactory accessory vent termination kit MUST be used in a directvent (2-pipe) system. See Fig. 45 for required clearances.Ventilated Combustion Air SystemsIn a ventilated combustion air option, the vent terminates anddischarges the flue products directly to the outdoors similar to adirect vent system. See Fig. 46 for required clearances.All air for combustion is piped directly to the furnace from a spacethat is well ventilated with outdoor air (such as an attic or crawlspace) and the space is well isolated from the living space orgarage. Combustion air requirements for this option are the same asthe requirements for providing outside air for combustion for asingle pipe vent system. Refer to the “Air For Combustion andVentilation Section.Provisions for adequate combustion, ventilation, and dilution airmust be provided in accordance with:U.S.A. Installations: Section 9.3 NFPA 54/ANSI Z223.1-2009,Air for Combustion and Ventilation and applicable provisions ofthe local building codes.Canadian Installations: Part 8 of CAN/CS-B149.1-10. VentingSystems and Air Supply for Appliances and all authorities havingjurisdiction.Non-Direct Vent (1-pipe) SystemIn a non direct-vent (1-pipe) system, all air for combustion is takenfrom the area adjacent to furnace, and all flue products aredischarged to outdoor atmosphere. Air for combustion must besupplied as described in the Air For Combustion and VentilationSection. Do not use an abandoned chimney to supply outside air tothe furnace. See Fig. 46 for required clearances.Provisions for adequate combustion, ventilation, and dilution airmust be provided in accordance with:U.S.A. Installations: Section 9.3 NFPA 54/ANSI Z223.1-2009, Airfor Combustion and Ventilation and applicable provisions of thelocal building codes.Canadian Installations: Part 8 of CAN/CS-B149.1-10. VentingSystems and Air Supply for Appliances and all authorities havingjurisdiction.A combustion air pipe to the outdoors is not required for a singlepipe vent system. A 12-in. (304 mm) long pipe with a 2 -inch (51mm) tight radius 90 degree elbow is required to be attached to thecombustion air pipe adapter on the furnace. (See Fig. 49)Locating the Vent TerminationGeneralNOTE: Termination Requirements for the Provinces ofAlberta and Saskatchewan are located at the end of thissection.Combustion -air (direct vent/2 -pipe system only) and vent pipemust terminate outside structure, either through sidewall or roof.For vent termination clearance, refer to Fig 45 for DirectVent/2 -Pipe system and Fig. 46 for Non -direct Vent/1 -Pipesystem. For exterior termination arrangements, refer to Fig. 47 forDirect Vent/2 -Pipe system and Fig. 48 for Non - Direct/1 -Pipesystem.Roof termination is preferred since it is less susceptible to damageor contamination, and it has less visible vent vapors. Sidewallterminations require sealing or shielding of building surfaces with acorrosive resistance material due to corrosive combustion productsof vent system.NOTE: (Direct Vent/2 -Pipe system ONLY) A factory accessorytermination kit MUST be used.When determining appropriate location for termination, considerthe following guidelines:1. Comply with all clearance requirements stated in Fig 45 orFig 46 per application.2. Termination or termination kit should be positioned wherevent vapors will not damage plants/shrubs or air conditioningequipment.3. Termination or termination kit should be positioned so thatit will not be affected by wind eddy, such as inside buildingcorners, nor by recirculation of flue gases, airborne leaves,or light snow.4. Termination or termination kit should be positioned where itwill not be damaged by or subjected to foreign objects suchas stones, balls, etc.5. 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. Follow all clearances as shown Fig 45.38
Allowable vent and combustion air terminations are shown in Fig.47.Ventilated Combustion AirThe vent pipe for a Ventilated Combustion Air System mustterminate outdoors. Follow all vent termination clearances shownin Fig 46. Allowable vent terminations are shown in Fig 48. Thecombustion air pipe terminates in a well -ventilated attic or crawlspace. Follow the clearances as shown in Fig. 50.The combustion air pipe cannot terminate in attics or crawl spacesthat use ventilation fans designed to operate in the heating season.If ventilation fans are present in these areas, the combustion airpipe must terminate outdoors as a Direct Vent System.Non-Direct Vent / 1-Pipe SystemThe vent pipe for a Non Direct Vent (1 -pipe) system mustterminate outdoors. Follow all vent termination clearances shownin Fig 46. Allowable vent terminations are shown in Fig. 48A combustion air pipe to the outdoors is not required for aNon -Direct Vent System. A 12 -inch long section of pipe with atight radius 2 -in. (50.8 mm) 90 degree elbow is required to beattached to the furnace.Termination Requirements for the Provinces of Alberta andSaskatchewanThe Provinces of Alberta and Saskatchewan require a minimumunobstructed distance of 4 ft. (1.2 M) from the foundation to theproperty line of the adjacent lot for vent termination of anyappliance with an input over 35,000 btuh. If there is less than 4 ft.(1.2 M) of unobstructed distance to the property line of theadjacent lot, no type of vent termination is permitted for applianceswith inputs greater than 35,000 btuh.There are no additional restrictions on unobstructed distancesgreater than 8 ft. (2.4 M). All single, two-pipe and concentric ventsmay be used, providing all other Code and manufacturer’srequirements in these instructions are adhered to. Refer to theappropriate Vent Termination section above for locating the ventterminationIf the unobstructed distance from the foundation to the propertyline of the adjacent lot is no less than 4 ft. (1.2 M) and no greaterthan 8 ft. (2.4 M), it will be necessary to re-direct the flue gasplume. In this situation, a concentric vent kit cannot be used. A2-pipe termination (or single pipe termination when permitted) thatre-directs the flue gas away by use of an elbow or tee, certified toULC S636 from the adjacent property line must be used. See Fig.49.The concentric vent kit currently cannot be modified to attach anelbow to the vent portion of the rain cap. A tee attached to the raincap could potentially direct the flue gas plume toward the intake airstream and contaminate the incoming combustion air for thefurnace.Refer to Fig. 49 for terminations approved for use in Alberta andSaskatchewan.Size the Vent and Combustion Air PipesGeneralFurnace combustion air and vent pipe connections are sized for2-in. (51 mm) pipe. Any pipe diameter change should be madeoutside furnace casing in vertical pipe. Any change is diameter tothe pipe must be made as close to the furnace as reasonablypossible.The Maximum Vent Length for the vent and combustion air pipe(when used) is determined from the Maximum Equivalent VentLength in Table 13 or 15, minus the number of fittings multipliedby the deduction for each type of fitting used from Table 14.The measured length of pipe used in a single or 2 -pipe terminationis included in the total vent length. Include a deduction for a Teewhen used for Alberta and Saskatchewan terminations. Concentricvent terminations, pipe lengths or elbows do not require adeduction from the Maximum Equivalent Vent Length.1. Measure the individual distance from the furnace to the terminationfor each pipe.2. Select a Maximum Equivalent Vent Length (MEVL) longerthan the measured distance of the individual vent and combustionair connections to the vent termination.3. Count the number of elbows for each pipe.4. For each pipe, multiply the number of elbows by the equivalentlength for the type of elbow used. Record the equivalentlength of all the elbows for each pipe.5. If a Tee is used on the termination, record the equivalentlength of the Tee used.6. Record the equivalent length of the termination to be used.7. Subtract the equivalent lengths of the fittings and terminationsfrom the Maximum Equivalent Vent Length.8. If the Maximum Vent Length calculated is longer than theindividual measured length of the vent pipe and combustionair pipe, then the diameter of pipe selected may be used.9. If the Maximum Vent Length calculated is shorter than theindividual measured length of either the vent pipe or thecombustion air pipe, recalculate the Maximum Vent Lengthusing the next larger diameter pipe.NOTE: The vent pipe and combustion air pipe must be the samediameter.NOTE: If the Maximum Vent Length for diameter of the pipeselected is longer than the measured length and the equivalentlength of all the fitting and terminations, recalculate using the nextsmaller diameter. If the recalculated Maximum Vent Length islonger than the measured length of the vent pipe and combustionair pipe, then that diameter of pipe selected may be used.When installing vent systems of short pipe lengths, use the smallestallowable pipe diameter. Do not use pipe size greater than requiredor incomplete combustion, flame disturbance, or flame senselockout may occur.Combustion Air and Vent Piping InsulationGuidelinesNOTE: Use closed cell, neoprene insulation or equivalent.The vent pipe may pass through unconditioned areas. The amountof exposed pipe allowed is shown in Table 12.1. Using winter design temperature (used in load calculations),find appropriate temperature for your application and furnacemodel.2. Determine the amount of total and exposed vent pipe.3. Determine required insulation thickness for exposed pipelength(s).4. When combustion air inlet piping is installed above a suspendedceiling, the pipe MUST be insulated with moistureresistant insulation such as Armaflex or other equivalenttype of insulation.5. Insulate combustion air inlet piping when run in warm, humidspaces.6. Install the insulation per the insulation manufacturer’s installationinstructions.NOTE: Pipe length (ft. / M) specified for maximum pipe lengthslocated in unconditioned spaces cannot exceed total allowable pipelength as calculated from Table 13 or 15.59TP5A39
