All air for combustion is takenfrom the outside atmosphere and allcombustion products are discharged tothe outdoors. Therefore, noventilation or combustion airopenings are required.IMPORTANT: The plastic combustionair and venting components are ofSchedule 40 PVC. If using ABS pipingensure that the solvent cement iscompatible for joining PVC to ABScomponents or use a mechanicalconnection that can withstand the venttemperatures and are corrosionresistant.INSTALLATION GUIDELINESAll exhaust piping must be installed incompliance with Part 7, “Venting ofEquipment,” of the latest edition of theNational Fuel Gas Code NPFA54/ANSI Z223.1-, local codes orordinances and these instructions.1. Vertical piping is preferred.2. All horizontal piping must slopeupward a minimum of 1/4 inchper foot of run so that condensatedrains toward the furnace.3. All horizontal runs must besupported at least every 4 feet.No sags or dips are permitted.4. IMPORTANT: Do not commonvent with any other appliance. Donot install in the same chase orchimney with a metal or hightemperature plastic pipe fromanother gas or fuel-burningappliance unless the requiredminimum clearances tocombustibles are maintainedbetween the PVC pipe and otherpipes. Minimum 3 ft. clearancerequired between combustion airinlet and any other exhaust.5. For horizontal runs where watermay collect, wrap the vent pipewith self-regulating 3 or 5 wattheat tape. The heat tape must beU.L. listed and installed per themanufacturer’s instructions.6. The minimum, pipe length is5 feet for combustion air andexhaust.7. Do not install elbows back toback. Allow at least 15” betweenelbows.Size the exhaust and combustion airintake pipes as specified in Tables 3and 4. These tables list the maximum!
