Do not install combustible materials on any of the black fireplace surround.

Burn only solid wood fuel or gas logs. Do not install a solid fuel burning insert or other

products not specified for use with this fireplace. These fireplaces are not approved for installation

in mobile homes.

Drafts

The fireplace should not be located in areas that create drafts (ie: frequently opened doors and central heating air inlets/outlets) that hamper the normal flow of air into the fire.

Gas Logs

If you plan to install a gas log, the gas line should be installed before framing the fireplace. The gas line

must be installed by a certified gas line installer.

Illustration Key

The following safety rules apply to offset installations (letters correspond with illustration above):

A. Height of the chimney is measured from the hearth to the chimney exit.

SR/SC36 SR/SC42 Maximum: 90' 90' Minimum:

Without Elbows 12' 6" 12' 6" With 2 Elbows* 14' 6" 14' 6" With 4 Elbows* 21' 0" 21' 0"

B. Do not use more than 4 elbows per chimney .

Attach the straps of the return (top) elbow to a structural framing member.

The offset (first) elbow of any pair does not have straps.

* In Canada, two (2) SK845 are allowed.

C. The chimney cannot be more than 30˚ (45˚ in Canada) from the vertical plane in any installation*.

D. The maximum length of the angled run of the total chimney system is 20 feet. (G plus H cannot exceed 20 feet.)

E. A chimney support (Model SKCS8) is required every 6 feet of angled run of chimney . Chimney supports are required for every 30 feet and 60 feet (SK8 pipe) or 20 feet and 40 feet (3-wall pipe) of vertical chimney height above the hearth.

Determine the offset distance of your chimney arrangement from the centerline of the fireplace to the centerline of the chimney where it is to pass through the first ceiling.

Note: This offset distance may not be your full offset distance. See Examples 2 and 3.

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 surfaces:

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 1/2 inch from a combustible back wall and 1/2 inch from a combustible

side wall or support. (Fig. 20, Page 14)

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 necessary 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 U.S./or 2 total 45˚ elbows in Canada) per fireplace may be used.

6. A guy wire stabilizer is required for chimneys extending 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 center of the chimney to the peak of the roof is 10 feet or less, the top of the chimney must be at least 2 feet above the peak of the roof, but never less than 3 feet in height above the highest point where it passes through the roof.

2. If a horizontal distance from the center of the chimney to the peak of the roof is more than 10 feet, a chimney height reference point is established that is on the surface of the roof a distance of 10 feet from the center of the chimney in a horizontal plane. The top of the chimney must be at least 2 feet above the reference point, but never less than 3 feet in height above the highest point where it passes

through the roof.

Chimney Supports

The chimney system is supported by the fireplace for vertical chimney heights less than 30 feet above the hearth. Chimney supports are required if the vertical height exceeds 30 feet with SK8 chimneys or 20 feet with 3-wall chimneys. Locate chimney supports at ceiling holes or other structural framing at 30 foot (SK8) or 20 foot (3-wall) heights. Spacing between chimney supports must not exceed 30 feet(SK8) or 20 foot (3-wall). Use Chimney Support Model SKCS8.

(Note: the SKCS8 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 2¹⁄₂" long when installed.)

Angled chimney runs require a support every six (6) feet in addition to the elbow straps. Chimney supports

are used for this function. (Fig. 9)

Chase Installation

A chase is a vertical box-like structure which encloses the fireplace and/or chimney. Chases are typically built on the outside of the house with fireplace opening cut into the outer wall of a room. (Fig. 5, Page 5)

If you need help in determining fireplace location or how the chimney system should be run, contact your Vermont Castings, Majestic Products dealer for

assistance.

Installation

■ 1. Insulating Fireplace Enclosure

For Cold Climates

If you live in a cold climate, it is not required but highly recommended that you insulate fireplace enclosure to eliminate cold air penetration as much as possible.

Insulate base of fireplace with a non-combustible insulation rated for a minimum of 300 degrees F. Insulating is very important for outside wall installations over a concrete slab. If fireplace is installed on a platform, insulation should be placed on top of the platform before fireplace is set. (Fig. 10)

When a fireplace is installed in a chase or on a outside wall, enclosure should be treated like any outside wall in a home. Insulation should be installed on the inside wall as well as the outside wall(s). In a chase, it is also a good idea to install a firestop at the first ceiling level above the fireplace and enclose the chase with sheeting material. Insulation may then be installed above sheeting material to assure the space around the fireplace is totally protected. (Fig. 5)

When installing the chimney , DO NOT caulk between outer pipe and firestop. It is vital that some air be allowed to flow through this very thin gap.

CAUTION: WHEN INSTALLING A FIREPLACE IN AN INSULATED ENCLOSURE, BE SURE ALL REQUIRED AIR SPACES ARE MAINTAINED. (Fig. 20, Page 14)
