6. Install the roof flashing: Seal the joint between the roof and the
flashing with roofing tar or silicone. For sloping roofs, Place the flashing
under the upper shingles and on top of the lower shingles -
approximately half of the flashing should be under the shingles. Seal
the joint between the roof and the flashing with roofing tar or silicone.
Nail the flashing to the roof using roofing nails. Place the storm collar
over the chimney and the flashing. Tighten it in place. Caulk the joint
between the chimney and storm collar with silicone.
7. Continue adding chimney sections until the required chimney height is
reached. See the drawing on page 7 to determine the correct height.
8. If the chimney height above the roof exceeds 5 feet then a roof brace
must be installed.
9. Fit the rain cap to the top of the chimney. Screw the four metal screws
provided through the straps and into the top chimney length.
CATHEDRAL CEILINGS
If your home has a cathedral ceiling (no attic space between the ceiling
and the roof), install the chimney and support as follows.
1. Situate the chimney in a convenient location as near as possible to the
appliance outlet. Cut and frame a hole in the roof for the support. The
sides of this hole must be vertical. See page 3 for hole size.
2. Place the support in the opening. Lower it to the correct height as
determined by the table and diagram on page 13.
Using a level, make sure the support is vertical. If the support extends
above the roof, cut it flush with the top of the roof. Nail the support to
the frame opening using 8 - 3" spiral nails or # 8 x 1½" wood screws.
Note: If you are using a 6" square support you may find it difficult to
screw it in place because it is fairly small inside.
We have provided angle brackets with this support which can be
screwed to the outside of the support box and nailed to surrounding
framing as required. Use a minimum of four # 8 x ½" metal screws per
bracket. In some cases these brackets may need to be trimmed (e.g.: to
fit under a flashing).
