1083292-UIM-A-0114Johnson Controls Unitary Products 31VENT SYSTEMThis furnace is certified to be installed with one of two possible ventconfigurations.1. Horizontal vent system. This vent system can be installed com-pletely horizontal or combinations of horizontal, vertical, or offsetusing elbows.2. Vertical vent system. This vent system can be installed completelyvertical or a combination of horizontal, vertical, or offset usingelbows.VENT APPLICATIONS AND TERMINATIONWhen selecting the location for a horizontal combustion air / vent termi-nation, the following should be considered:1. Observe all clearances listed in vent clearances in these instruc-tions.2. Termination should be positioned where vent vapors will not dam-age plants or shrubs or air conditioning equipment.3. Termination should be located where it will not be affected by windgusts, light snow, airborne leaves or allow recirculation of fluegases.4. Termination should be located where it will not be damaged orexposed to flying stones, balls, etc.5. Termination should be positioned where vent vapors are not objec-tionable.6. Horizontal portions of the vent system must slope upwards and besupported to prevent sagging.7. Direct vent systems must be installed so the vent and the combus-tion air pipes terminate in the same atmospheric zone. Refer toFigures 36 or 37.VENTING MULTIPLE UNITSMultiple units can be installed in a space or structure as either a singlepipe configuration or a two-pipe configuration.The combustion air side of the single pipe configuration shown in Figure42 is referred to in these instructions as ambient combustion air supply.Follow the instructions for ambient combustion air installations, payingparticular attention to the section on air source from inside the building.The vent for a single pipe system must be installed as specified in theventing section of these instructions with both vents terminating asshown in Figure 35. Each furnace must have a separate vent pipe.Under NO circumstances can the two vent pipes be tied together.The combustion air side of the two-pipe configuration shown in Figures36 and 37 can be installed so the combustion air pipe terminates asdescribed in outdoor combustion air or ventilated combustion air sec-tions in these instructions. Follow the instructions for outdoor combus-tion air or ventilated combustion air and the instructions for installing thevent system with the vent terminating as shown in Figure 38 or 39. Thetwo-pipe system must have a separate combustion air pipe and a sepa-rate vent pipe for each furnace. Under NO circumstances can the twocombustion air or vent pipes be tied together. The combustion air andvent pipes must terminate in the same atmospheric zone.FIGURE 35: Termination Configuration - 1 PipeCondensation in Intake PipeInstallations where the furnace and intake pipe are to be located in aconditioned space and in a region that may have hot, humid weatherextending several consecutive days will have condensate form in theintake pipe. Use of the supplied intake drain will ensure that any con-densate will be safely diverted away from the internal components ofthe furnace. Proper venting installation (of both intake and exhaust)and sealing any equipment air leaks that might contact the intake pipewill help reduce condensation.12” Min.12” Min.Maintain 12” minimum clearanceabove highest anticipated snow level.Maximum 24” above roof.FIGURE 36: Termination Configuration - 2 PipeFIGURE 37: Termination Configuration - 2 Pipe BasementMaintain 12” minimumclearance abovehighest anticipatedsnow level.12” vertical separationbetween combustion airintake and vent. 12” minimumbelow overhang12” minimumseparation betweenbottom ofcombustion air pipeand bottom of vent.Maintain 12”minimum clearanceabove highestanticipated snowlevel or grade,whichever is higher.12” MIN.12” MIN.OVERHANG12” Minimumbelow overhang12” Minimumseparation betweenbottom ofcombustion airintake andbottom of ventMaintain 12”minimumclearanceabove highestanticipated snowlevel or grade,whichever is higher
