NOTES:
1. The chimney may be enclosed or un-enclosed. Maintain 2" clearance to combustible materials. Do not fill the
2" space around the chimney with insulation or any other material.
2. A wall band must be used to secure the chimney to the wall. Maximum distance between wall bands is 8 feet.
3. The minimum horizontal length of chimney extending past the inside wall is 4 inches.
4. The distance between the stovepipe and a parallel combustible wall or ceiling must not be less then 18". The
distance between the horizontal stove pipe and the un-shielded vertical wall through which the insulated chim-
ney passes is determined by the Wall Radiation Shield.
5. If an exterior installation is to be enclosed, allow for access to base of Tee to facilitate required cleaning.
6. The minimum distance between the bottom of the chimney and any horizontal combustible surface is 12".
Through the Wall Installation - Wall Support and Wall Radiation Shield
1. Determine where the chimney will pass through the wall.
For concrete walls cut a hole slightly larger than the chimney.
For combustible walls cut and frame a hole (See TABLE 3 for size)
2. Combustible wall:
From outside, put the exterior portion of the wall radiation shield in the hole. Nail the radiation shield in place
using 4, 2" nails or # 8 * 1 1/2" wood screws.
3. Fasten the Wall Support to the outside wall. The Wall Support must be adjusted so that the clearance to a com-
bustible wall is at least 2".
4. Stack the next chimney length in place. Fasten the lengths together using one stainless steel metal screw in
each pre-punched hole. Continue until the required chimney height is installed.
5. Install a Wall Band at 8' intervals. The Wall Band should be adjusted to ensure the chimney is vertical and at
2" (or more) clearance to combustibles.
6. If the chimney extends above the roof more than 5' above the last lateral brace, it should be secured to the roof
using a Roof Brace (RB).
7. Fit the rain cap to the top of the chimney. Screw the metal screws provided through the straps and into the top
chimney length.
FROM INSIDE
8. Fasten the flue extension to the horizontal chimney length sticking into the room.
9. Put the interior portion of the wall radiation shield (WRS) in the hole in the wall and push it until it stops against
the wall. Fasten it to the wall.
NOTE:
If the chimney passes through the roof, cut a hole large enough to provide 2" clearance between the chimney and
the roof. See the table on page 11 for the size. Put the roof flashing in place. Seal the joint between the roof and
the flashing with roofing pitch. For sloping roofs, place the flashing under the upper shingles and on top of the
lower shingles. Nail the flashing to the roof using roofing nails. Place the storm collar over the chimney and push
down until the collar contacts the spacer. Caulk the joint between the chimney and collar with silicone caulking.
