fireplace)

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.
