What must liquid combustion by products of condensing appliances be done with according to installation instructions?

Liquid combustion byproducts from condensing appliances must be collected and discharged according to the installation instructions. This is essential because condensing appliances, such as high-efficiency furnaces and boilers, create water as a result of the condensation process during combustion. The water contains impurities and can be acidic due to the presence of carbonic acid formed from carbon dioxide in the combustion process.

Proper management of these byproducts is critical for several reasons. Firstly, discharging the liquid safely helps prevent potential damage to the appliance and ensures efficient operation. It also mitigates the risk of harm to the environment by preventing the release of pollutants. Systems must be designed to collect this condensate and direct it to a suitable drain or disposal system that adheres to local plumbing codes and regulations.

Understanding the proper techniques for handling these byproducts is vital for ensuring the longevity of the equipment and maintaining safety and compliance with the applicable mechanical codes and standards.
