High Efficiency Gas Furnace Venting
Traditional gas fired forced air furnaces produce hot combustion exhaust gasses and therefore need metal vent pipes or chimneys.
High efficiency gas furnace venting. Venting for high efficiency gas furnaces assembly. It is classified as type bh venting. Here are some good venting practices. Other aspects of high efficiency furnace venting.
With a replacement high efficiency furnace the existing vent pipe does not work for water heater only because the vent is too large. Due to the condensing nature of a high efficiency furnace its venting must be made of a material that is resistant to corrosion. The photo below shows typical combined furnace water heater venting. One of the most crucial however is the method in which it is vented.
Here s what you need to know about high efficiency furnace venting. This is mostly stuff i learned during a training session from ipex one of the major manufacturers of plastic piping with a little of my personal experience and tips first of all venting must be planned in order to be sized properly. 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. Venting for high efficiency gas furnaces materials.
There are several other important aspects of high efficiency furnace venting. In a great majority of cases plastic piping is used to vent high efficiency equipment. The pvc pipes are used for air intake exhaust gas and to remove the corrosive condensation resulting from the combustion process.
