High Efficiency Gas Furnace Exhaust

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.

High efficiency gas furnace exhaust. There are several other important aspects of high efficiency furnace venting. High efficiency or condensing furnaces exhaust the combustion gases and bring in fresh air through pvc pipes to the outside usually routed through the sidewall of the house. Traditional gas fired forced air furnaces produce hot combustion exhaust gasses and therefore need metal vent pipes or chimneys. It is classified as type bh venting.

A conventional furnace vents these combustion gases through a vertical exhaust system that is attached to the furnace. This condensing process along with the one that occurs within the high efficiency furnace itself creates moisture that can collect and freeze around and inside exhaust pipes. Venting for high efficiency gas furnaces materials. Other aspects of high efficiency furnace venting.

The pvc pipes are used for air intake exhaust gas and to remove the corrosive condensation resulting from the combustion process. In a great majority of cases plastic piping is used to vent high efficiency equipment. This high efficiency venting system must be installed when you install the new furnace. A high efficiency furnace uses a different type of venting system because it extracts the heat that remains in those combustion gases before venting the resultant mixture of water and carbon dioxide.
