CHIMNEY HEIGHT
The national Fire protection Association
Standard #211 states: “Chimneys shall extend
at least three feet above the highest point
where it passes through the roof of a building,
and at least two feet higher than any portion of
a building within ten feet.” (Fig. 1) Due to the
overlap of the joints, subtract 1-1/2 inches from
each Chimney Section’s height to calculate
installed height.
CHIMNEY ENCLOSURE
REQUIREMENTS
Through Rooms: Interior chimneys shall
be enclosed where they extend through
closets, storage areas, occupied spaces, or
anywhere where the surface of the chimney
could be contacted by persons or combustible
materials (including insulation). The air space
between the outer wall of the chimney and the
enclosure shall be at least 2 inches
Multi-Story: Consult local building code
officials for requirements in your area. 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.
Cold Climates: In cold climates, chimneys
mounted on an outside wall should be
enclosed in a chase. exterior chases reduce
condensation and creosote formation, and
enhance draft.
APPLIANCE RECOMMENDATIONS
Always follow the fireplace manufacturer’s
installation instructions.
Installation: Install your fireplace as described
by the fireplace manufacturer. Be sure to
maintain all required clearances.
Flues: Connect only one appliance per
chimney.
Operation: Follow the fireplace safety manual
for maximum efficiency and safety. Do not
over fire. Any damage to the fireplace or
chimney can possibly void your warranties.
Fuels: Do not burn driftwood, plastic, or
chemically treated wood such as railroad ties.
They are corrosive to your chimney system.
Follow the fireplace manufacturer’s instructions
regarding fuels.
MASONRY FIREPLACE
INSTALLATION
1. Place Fireplace: Position the fireplace
according to the fireplace manufacturer’s
installation instructions. The flue outlet should
be placed between the rafters or joists above,
if possible.
2. Determine Chimney Size: Follow the
fireplace manufacturer’s instructions for
chimney size or use Table 2 (pg 11) to
determine the correct diameter chimney for
your fireplace.
