High Efficiency Gas Furnace Exhaust Temperature

It moves the air with a circulating fan.

High efficiency gas furnace exhaust temperature. While the condensing furnace is different in its design and repair needs it does have some similarities to a conventional furnace like a conventional furnace it takes in cold air from the house and runs it through an air filter. High efficiency or condensing furnaces exhaust the combustion gases and bring in fresh. 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. Temperature testing is done to assure the materials ie.

There are several other important aspects of high efficiency furnace venting. And it has a gas burner with electronic ignition although condensing. On 90 high efficiency furnaces what should the vent temperature be. Schedule 40 pvc pipe are within the safe working range of the equipment.

Vent pipe blocking the exhaust flow. This high efficiency venting system must be installed when you install the new furnace. To start this discussion you first need to understand how the venting system is tested for a 90 efficient furnace. The pvc pipes are used for air intake exhaust gas and to remove the corrosive condensation resulting from the combustion process.

In high efficiency models the lower temperature of the exhaust can allow moisture a by product of combustion to condense in the flue especially when outdoor temperatures drop into the 20 s or below. Whether the furnace is a standard a conventional furnace 50 70 mid efficiency 70 80 or a high efficiency furnace the provision for combustion air and flue gas vent systems is very important. Other aspects of high efficiency furnace venting.
