Passing Through a

Combustible Wall or Ceiling

An approved pass-through device is always required when a vent passes through a combustible wall or ceiling. Check with the maker of the vent system for the correct listed devices that are available. A listed pass-through device is required whether or not the installation includes decorative pipe around the Type B venting system. NOTE: It is essential to seal between the ceiling support (sometimes called a ‘firestop spacer’) and the decorative pipe, if installed, with a high-temperature silicone sealant. (Fig. 6)

Complete the venting system installation according to the manufacturer’s instructions.
