*The first flue offset closest to the top of the unit must be a minimum distance of 12 inches from the top of the fireplace.
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.
NOTE: 30° or 45° offsets may be installed back to back.
ADDING CHIMNEY SECTIONS
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.
