1. Move the fireplace into position. Try to center the ex-
haust flue of the fireplace, midpoint between two joists to
prevent having to cut them. Use a plumb bob to line up the
centre.
2. Cut and frame an opening in the ceiling to provide a
minimum clearance of 2" between the outside of the chim-
ney and any combustible material. DO NOT FILL THIS
SPACE WITH ANY TYPE OF MATERIAL! Nail headers
between the joists for extra support. Firestop spacers must
be placed on each framed opening in any floor or ceiling
that the chimney passes through.
3. Hold a plumb bob from the underside of the roof to
determine where the opening in the roof should be. Cut
and frame the roof opening maintaining proper 2" clear-
ances.
Add chimney sections, securely, to the required height. Use
a rafter radiation shield whenever the chimney system is
enclosed within an attic area.
- Chimney must extend 3' above the roof.
- Chimney must extend 2' above any portion of the roof
within 10' of the chimney.
