True or False: A venting system is allowed to extend into a fabricated air duct.

A venting system must be designed and installed according to specific building codes and standards, which generally prohibit it from extending into a fabricated air duct. This is largely due to safety considerations, as combining venting systems with air ducts can create pathways for contaminants, odors, or combustion gases to enter the living space, potentially compromising indoor air quality and safety.

Furthermore, the function of a venting system is to expel gases and moisture generated during appliance operation, whereas air ducts are designed to transport conditioned air throughout a building. Mixing these systems could disrupt their intended functions and lead to operational inefficiencies.

Regulatory guidelines are clear in distinguishing the purposes of each system to ensure both effective ventilation and proper air distribution, thus reinforcing the assertion that a venting system cannot extend into a fabricated air duct.
