What is the flue collar designed for?

The flue collar is designed specifically to connect an appliance, such as a water heater or furnace, to a draft hood or venting system. This connection is crucial because it allows the safe and effective venting of combustion gases produced by the appliance to the outside atmosphere. The flue collar facilitates the proper alignment and sealing of the vent, ensuring that harmful gases do not enter the living space and that the appliance operates efficiently.

When an appliance is properly vented, it enhances safety by reducing the risk of carbon monoxide buildup and ensures compliance with building codes. The venting system must be adequately sized and installed to handle the volume of gases produced during operation, making the flue collar a critical component of the overall venting process.
