I. BASIC FIREPLACE AND CHIMNEY
REQUIREMENTS
A Sierra woodstove may be installed using an all masonry
fireplace build in accordance with the Uniform Building
Code. The first step in this type of installation is to
determine the acceptability of the fireplace and chimney for
use with a woodstove. Both the construction and condition
of the fireplace are important considerations when
installing a wood stove. Do not install this stove in a poorly
constructed fireplace or chimney.
The following are general guidelines for a safe installation
and are based on recommendations of the National Fire
Protection Association (NFPA). Contact your local building
code agency or fire safety inspector for specific details.
Local codes may vary by area.
1. The chimney should have a fire clay liner in good
condition. Loose or cracked liner sections can be
hazardous. If the chimney does not have a liner, one
can be installed by a qualified professional. Some metal
liners area acceptable to use. Check with your stove
dealer or local building code agency for acceptability of
these liners.
2. No part of the chimney should have any leaks, missing
masonry, cracks, loose mortar or soft mortar.
3. There should be no mortar or parts of the chimney
blocking the chimney flue.
4. There should be a minimum 2-inch clearance between
any part of the fireplace or chimney and any com bustible
materials.
55. The fireplace and chimney should be built on a solid
concrete footing supported by the ground and not
attached to the house.
Older chimneys are sometimes supported by the
framework of the building itself. These can be
structurally unsound due to settling and shifting of the
building and possible cracking of the chimney itself.
6. The chimney must have a good natural draft and should
be self-starting. A chimney that has poor draft and is
subject to draft reversal should be repaired or replaced
before using.
7. The chimney should be the proper size. Some fireplace
chimneys are quite large and will cause poor stove
performance and excessive creosote. The rule of
thumb is that the chimney flue should be roughly no
more than three times the flue opening on the stove. A
6 inch stove flue will work in an 8 inch by 12 inch
fireplace flue. It may be necessary to install another
liner in an oversized chimney. Use a 24 gauge flue, and
chimney connector. Use at least 3 screws.
8. The chimney should extend at least 3 feet above the
roof and at least 2 feet above any point on the roof
within 10 feet.
9. This stove must be used alone in the chimney. Any
unused opening must be permanently sealed with
masonry by a skilled brick mason. A clip-in type flue
liner is not acceptable for this use because of the
possibility of it coming loose during a chimney fire and
possibly causing the fire to spread.
Remember to have your chimney inspected for leaks and
blockage before you install your stove.
Draft Requirements
Draft id the force which moves air from the appliance up
through the chimney. The amount of draft in your chimney
depends on the size, height and general condition of your
chimney, local geography, nearby obstructions, and other
factors. Inadequate draft will cause the appliance to leak
smoke into the room when starting a fire or adding fuel to
the existing fire. Excessive draft, on the other hand, may
cause excessive temperatures in the appliance, burning
the wood too quickly and damaging the unit.
Minimum Chimney Requirements
Size Height Draft
6 x 6 15 ft .06 W.C.
Note: 9 out of 10 times, dirty glass, lack of “heating”, or
failure to continue burning after the door are shut is
evidence of inadequate draft.
In all cases, if you experience anything unusual with your
Evolution, your Sierra dealer is the local expert on local
conditions, and you need to contact him or her.
