Venting gas furnace through chimney.

Consequences of improperly assembled vent pipes problematic chimney flue deteriorating chimney walls can be sometimes fatal fire and carbon. Higher btuh furnaces produce higher flue gas temperatures. For many homes a gas furnace is the preferred heating device it has proven to be an efficient and reliable way of meeting household heating needs over the years. The vent pipe of your gas furnace plays an important role by carrying all toxic gases created during the combustion within the furnace out of the building.

Kits in this category include those designed for natural draft appliances using gas oil or wood. The conditions explained in this post also apply to the wood burning appliances. You should know how to vent a gas furnace and get rid of the harmful gases for the health and safety of anyone living in your building. A conventional natural gas furnace will vent the dangerous combustion gases through a simple vertical exhaust system that is attached to the furnace.

The vent pipe or flue is a vital component of the furnace that transmits emissions from the combustion process out of the building. Traditional gas fired forced air furnaces produce hot combustion exhaust gasses and therefore need metal vent pipes or chimneys. The exhaust system typically uses metal venting often routed into a chimney stack to exhaust the combustion gases created in the furnace fire chamber. 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.

Of the vent plus the furnace input and efficiency are factors affecting the temperature of the flue gases. As well as those suitable for category i gas fired appliances with b vent or appliances with a draft hood. On the other hand the higher the efficiency of a furnace the lower the flue gas temperature. Two cases which can cause poor venting are the oversizing of the vent or reducing the.

Proper furnace water heater venting is an extremely important issue which depends on the performance of the house chimney chimney flue or other exhaust assemblies.
