Two Pairs (4) Offsets
Minimum chimney
height is 19’.
NOTE:
In problematic
locations (areas with
high wind or at altitude,
etc.) additional chimney
height above the
specified minimum may
be necessary to reduce
wind-induced down
drafts, back puffing, or
smoke spillage. By
adding additional
chimney, the fireplace
will have increased draft
and encounter less
negative operating
characteristics.
Chimney must be totally
enclosed when passing
through living space with a
minimum 2" (51mm)
clearance to combustibles.
