1. Cut and frame the required holes in the floor, ceiling
and roof where the chimney will pass through. Use a
plumb bob. The framing size is 14 1/4” square.
2. From below, install a radiation shield in each floor
through which the chimney passes. At the attic level,
install a storm collar above the radiation shield as
shown in (Figure 8).
3. Place the first chimney length on the fireplace.
Secure the chimney length to the fireplace with the
three screws provided.
The chimney must extend at least 3 ft. above its point
of contact with the roof and at least 2 ft. higher than
any wall, roof, or building within 10 ft. of it. Refer to the
Excel instruction installation flue height requirements
for penetration above a chase.
If the chimney is higher than 5 ft. above the roof, it
must be secured using a roof brace.
4. Put the roof flashing into place. Seal the joint between
the roof and the flashing with roofing tar. 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.
If the chimney is enclosed to the roof:
USA: use a vented flashing
Canada: use a roof radiation shield (ERRS)
and a regular flashing
5. Place the storm collar over the chimney and flashing.
Seal it around the chimney with silicone sealer (DO
NOT use roofing tar).
6. Fit the rain cap on the chimney. Secure it tightly in
place.
7. Wash the roof flashing with solvent (or vinegar if the
flashing is galvanized), then paint it with exterior
paint.
Read the Excel Chimney installation manual concerning
requirements for supports bracing anchors, etc.
