What characterizes a Type B Gas Vent?

A Type B Gas Vent is specifically designed for venting listed gas appliances that feature draft hoods. These vents are engineered to accommodate the products of combustion produced by gas appliances, ensuring safe and efficient venting to the exterior of the building. The design of the Type B vent allows for a certain degree of positive pressure, which is critical for maintaining proper airflow and preventing backdrafts.

Venting is an essential aspect of gas appliance operation. Appliances with draft hoods require a venting system that can handle the specific exhaust they produce, and Type B vents are built to meet these needs. This specificity in application reinforces safety standards and operational efficacy when dealing with gas-fired appliances.
