Ceiling height construction window size and placement and dozens of other variables all need to be considered to properly size a heating and or cooling system.
Goodman furnace exhaust pipe size.
Traditional gas fired forced air furnaces produce hot combustion exhaust gasses and therefore need metal vent pipes or chimneys.
Outdoor exhaust intake combustion pvc venting.
A professionally conducted load calculation is the foundation of an effective system.
Sizing the equipment load requires the consideration of several factors.
Measure the diameter of the circular flange where the vent attaches at the back of the furnace.
When compared to the natural vent this one is more flexible although it is also costlier.
In contrast modern high efficiency condensing furnaces exhaust much cooler gasses and need only plastic pipe materials such as pvc cpvc or abs for their exhaust vents some high efficiency furnaces also include a plastic pipe for intake area and all types.
Also known as the induced draft fan this one has a fan that is located on the end of the pipe.
