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 3/4 inch from a combustible side wall or support. (Fig. 20, Page 14)

Planning the Chimney Run

Determine how the chimney will be run, length of run and chimney components required to complete the job. (Fig. 6) Never install a chimney below minimum heights.

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 degrees 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 feet.

5.No more than 2 offsets (4 total 30˚ elbows in) per ﬁreplace may be used.

6.A guy wire stabilizer is required for chimneys extend- ing more than 6 feet above a roof line.

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. 8)

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