Planning Information

Preplanning an installation is very important to ensure
safety and to save time and money. An installer must
predetermine where a ﬁreplace will be set and how the
chimney system will be run.

Mounting the Fireplace

A ﬁreplace may only be mounted on the following sur-
faces:
1. A ﬂat combustible surface.
2. A raised wooden platform.
3. A concrete block or other solid object placed beneath

each of the four (4) corners of the ﬁreplace.

The ﬁreplace

must

be spaced 3/4 inch from a combus-

tible back wall and 7/16 inch from a combustible side
wall or support. (Fig. 17, Page 12)

Planning the Chimney Run

Determine how the chimney will be run, length of run
and chimney components required to complete the
job. (Fig. 3)

Never

install a chimney below minimum

heights.

The Ten Foot Rule

Major U.S. building codes specify a minimum chimney
height above the roof top. The “Ten Foot Rule” is a ﬁre
safety rule and not a draft rule. To ensure proper draft,
it is recommended that you always meet or exceed the
“Ten Foot Rule,” especially when installing a termination
on a high pitch roof. (Fig. 5)
The key points of the “Ten Foot Rule” are:
1. If the horizontal distance from the chimney to the

peak of the roof is 10’ (3m) or less, the top of the
chimney must be at least 2’ (610 mm) above the
peak of the roof, but never less than 3’ (914 mm)
in height above the highest point where it passes
through the roof.

2. If a horizontal distance from the chimney to the peak

of the roof is more than 10’ (3 m), a chimney height
reference point is established on the surface of the
roof a distance of 10’ (3 m) from the chimney in a
horizontal plane. The top of the chimney must be
at least 2’ (610 mm) above the reference point, but
never less than 3’ (914 mm) in height above the high-
est point where it passes through the roof.

In planning a chimney system, it is important to know:

1. The height of a chimney is measured from the hearth

to the exit point on the termination.

2. A chimney cannot be offset more than 30° from a

vertical plane.

3. A chimney may run straight up or it may be neces-

sary to offset it to avoid obstructions.

4. The maximum length of an angled run (total chimney

system) is 20’ (6 m).

5. No more than 2 offsets (4 total 30° elbows in U.S./or

2 total 45° elbows in Canada) per ﬁreplace may be
used.

6. A guy wire stabilizer is required for chimneys extend-

ing more than 6’ (1.8 m) above a roof line.

Chimney Supports

The chimney system is supported by the ﬁreplace for
vertical chimney heights less than 20’ (6 m) above the
hearth. Chimney supports are required if the vertical
height exceeds 20’ (6 m). Locate chimney supports
at ceiling holes or other structural framing at 20’ (6m)
heights. Spacing between chimney supports

must not

exceed 20’ (6 m). Use Chimney Support Model SKCS8
for SK8 chimney, and Model 11CS for 11CF chimney.

(Note: the chimney support can not be mounted
directly to the ﬁreplace.)

Support provided by elbow

straps fulﬁlls the support requirement only if they are
spaced as previously described. (A chimney support is
2

¹⁄₂

" (64 mm) long when installed.)
