FLUE RECOMMENDATIONS
WHAT SIZE CHIMNEY SHOULD BE
USED?
The Chimney size to use is either six (6)
or (8) inch round or an 8 x 8" square. If
you use a rectangular chimney, the mini-
mum area it may be is 39 square inches.
"Class A" chimneys are those made from
tile-lined masonry (brick or block) or an
independent laboratory approved all-
fuel factory-built chimney.
CAUTION!
Only a "Class A", all-fuel chimney in-
tended for use with solid fuel should be
used.
Chimney experts have determined that
the flue termination should be at least 2'
above the highest portion of the roof that
is within a 10' radius.
The flue termination should be at
least 3' above the roof line.
The termination cap should be
designed to inhibit downdrafting
without restricting the exhaust
discharge.
