What type of vent is used on a high efficiency condensate furnace?

In a high efficiency condensate furnace, the appropriate type of vent is PVC S636. This type of venting is specifically designed to handle the corrosive condensate and high moisture levels associated with high efficiency appliances. PVC S636 is a well-suited material for venting because it demonstrates excellent resistance to corrosive gases and is capable of withstanding the acidic conditions that can result from the combustion process in these furnaces.

High efficiency furnaces, also known as condensing furnaces, operate by extracting more heat from the flue gases, which leads to the production of water vapor and condensate. PVC venting effectively channels this condensate without degrading or compromising the integrity of the venting system. In contrast, other materials may not provide the same level of protection against corrosion or may not be compatible with the condensate generated, leading to potential failures or leaks in the system. Thus, the choice of PVC S636 as a venting material is imperative for ensuring safe and effective operation of high efficiency condensate furnaces.
