What type of pipe is used for furnace exhaust?
PVC pipes are used on conventional and sealed combustion high-efficiency furnaces. This is because their combustion process produces and exhausts gases and condensate at a rapid pace, which would corrode metal materials in a short time.
Can PVC be used for furnace vent?
Suitable materials for the vent and condensate pipes include PVC (polyvinyl chloride), CPVC (chlorinated polyvinyl chloride), and ABS (acrylonitrile-butadiene-styrene) plastic pipe, depending on the furnace’s specified exhaust gas temperature.
What size is furnace vent pipe?
Your furnace will require a 2 or 3 inch vent pipe depending on your furnace size even though all of the furnaces have a 2 inch opening where the vent pipe connects.
What is a concentric kit in HVAC?
The Concentric Vent allows both the intake for combustion air and the exhaust vent to pass through a standard roof or sidewall. This is an alternative to the standard two pipe intake/vent shown in the basic furnace installation instructions.
What is a flue pipe on a furnace?
The flue pipe is a duct pipe that vents, or exhausts, gases from inside the home to the outside. A byproduct of combustion contains carbon monoxide and other dangerous compounds.
How long can a furnace exhaust pipe be?
The maximum vertical distance you can run a furnace exhaust vent is about 15 feet. If there is a forced air inlet within 10 feet of the exhaust vent, the exhaust gas ventilation terminal should be positioned at least 3 feet above it.
Can a 80 furnace through wall?
An 80% efficient furnace CAN be side wall vented per National Fuel as Code 7.3. 4 with the use of a “mechanical draft system of either forced or induced draft design”. You CANNOT just take the vent off an 80% efficient furnace and run it out a side wall. You need to use an auxiliary power inducer.
