House With Furnace On The Roof

Gases produced during combustion are very hot and as such easily rise through the flue.

House with furnace on the roof.

A gas furnace uses a double wall flue pipe for its vent. However these combustion gases contain. The air is then vented outside through a b vent pipe which is set vertically to expel combustion air through the roof. A rusted area on a vent pipe not only lets rainwater enter the attic but also allows potentially dangerous downdrafts to push fumes into the home s living space.

The vents consist of circular or oblong pipe that attaches. You can use this it works for gas as well as oil fired furnace answered by. If your furnace has an afue rating of 90 or lower it probably exhausts the gases though the flue pipe on your roof. All gas furnaces must be vented to allow exhaust gases from the combustion process to escape.

The constant exposure to weather weakens a gas furnace roof vent s outer liner and termination cap. Could this be use for my oil furance cap on my roof. Well the flue which is a term referring to the vent pipe is basically the important component from the furnace that will transport the emission from the combustion heating process to the outside area of the house. How to remove old furnace roof venting.

The exhaust system typically uses metal venting often routed into a chimney stack to exhaust the combustion gases created in the furnace fire chamber. You don t have to worry about any toxic gas or combustion byproduct that will linger inside the house if you have the flue.
