Passing Through a
Combustible Wall or Ceiling
An approved pass-through device is always required
when a vent passes through a combustible wall or ceil-
ing. 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 installa-
tion includes decorative pipe around the Type B venting
system. NOTE: It is essential to seal between the ceil-
ing 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.
