CHIMNEY PLACEMENT
When deciding the location of your chimney, try to avoid modifications to roof beams,
trusses, wall studs, and other structural components of the building.
CHIMNEY ENCLOSURE REQUIREMENTS
Passing Through Rooms:
Interior chimneys shall be enclosed where they extend
through closets, storage areas, occupied spaces, or any place where the surface of the
chimney could be contacted by persons or combustible materials. The space between
the outer wall of the chimney and the enclosure shall be at least 2 inches (Fig 2).
Multi-Story Installations:
Consult local building codes for
requirements in your area. In the U.S., the National Fire
Protection Association Standard #211 states: “Factory-built
chimneys that pass through floors of buildings requiring the
protection of vertical openings shall be enclosed with
approved walls having a fire resistance rating of not less than
one hour when such chimneys are located in a building less
than 4 stories in height, and not less than 2 hours when such
chimneys are located in a building more than 4 stories in
height.” In Canada, except in single-family and two family
dwellings, chimneys which extend through another story must
have an enclosure with a fire resistance rating equal to or
greater than that of the floor or roof assembly through which
they pass.
