What must happen to the liquid combustion byproducts from condensing appliances?

Liquid combustion byproducts from condensing appliances are typically in the form of condensate, which is generated during the combustion and cooling process. For these appliances, it is essential that the condensate is collected properly to prevent any potential water damage or contamination in the environment.

The collection of these byproducts is vital for a few reasons:

1. Safety: Collecting the condensate helps minimize the risk of spills and subsequent water damage that could lead to mold growth or structural issues within a building.

2. Code Compliance: Building codes, including mechanical codes, often have specific requirements regarding the handling and disposal of condensate. Proper collection aligns with these standards, ensuring that the installation is safe and compliant.

3. Environmental Responsibility: Properly managing liquid byproducts also prevents contamination of local water sources and respects environmental regulations.

In contrast, other options like recycling, filtering, or discharging may not adequately address the practical and regulatory needs connected with handling condensate from condensing appliances. While some discharging may be allowed, it must ensure compliance with local codes and guidelines. However, the key requirement is the collection of these liquids for safe and responsible management.
