Make sure there isn’t a screen installed on the flue/vent pipe (the one that blows the exhaust outside). Removal of latent heat results in the condensation of flue gas water vapor. This furnace removes both sensible and latent heat from the combustion gases. VENTING GAS APPLIANCES NFPA 54 CODE •80000 Furnace and 40000 Water Heater Category IV Direct Venting Intake and Exhaust Pipes. Direct vent exhaust clearance distances for gas fueled appliances: Table & illustrations of the required space between a direct or side-wall vent for a gas fired heating appliance and building windows, doors, corners, gas meter, air intakes, sidewalks, balconies & decks and other building features. The vent terminal should be located so as to minimize the total length and number of elbows in the piping. Finally, we have a few propane connections (elbows) and the direct vent exhaust port. Do not operate wall furnace unless it is connected to the factory supplied vent system with vent cap in place. Preserve indoor air quality - Rinnai Direct Furnaces use outside air for combustion and the exhaust gasses go directly to the outside. I am having a natural gas high efficiency furnace installed in 2 days. We no longer have a relationship with a parts store.
