* The first flue offset closest to the top of the appliance must be a
minimum distance of 12" (30.5cm) from the top of the appliance.
A. Move the appliance into position. Try to center the exhaust
flue of the appliance, midpoint between two joists to prevent
having to cut them. Use a plumb bob to line up the centre.
B. Cut and frame an opening in the ceiling to provide a
minimum clearance of 2" (50.8mm) between the outside of
the chimney 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.
C. 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" (50.8mm) clearances.
note:
30° or 45° offsets may be installed back to back.
