Problem Description Can Occur when.. Possible Solutions
The appliance is a see-
through replace
Among critical replaces is
the so-called “see-through”
replace – a replace that
is open into two rooms. The
replaces must capture
the air in the same way as
an exhaust hood, which
requires good draft in order
to maintain a high velocity
over the replace opening.
Very often turbulence can
be experienced inside the
smoke chamber, and smoke
problems can occur.
• Fireplace was converted
from a one-sided replace
into a see-through
• No smoke chamber
• Opening up into rooms
with different pressures (one
room has stairs, vaulted
ceiling etc., the other one
does not)
• Close one side of the
see-through replace.
• Redesign the smoke
chamber to provide a better
ow.
• Redesign and rebuild
the chimney to provide the
proper draft.
• Install a mechanical draft
system
The appliance is in the
wrong place.
Performance problems can
also be experienced if the
appliance is in the wrong
place. The chimney is put
in an impossible situa-
tion where it is not given a
chance to work.
• A replace or stove located
in the basement of a
building.
• The chimney makes too
many changes of directions
(too many elbows) to get
ue gases from the
appliance to the outside.
• Redesign the venting
system – if possible
• Remedies to increase
frontal velocity include
the following: (1) increase
chimney height (using the
same ue area) and extend
the last tile 6 inches or more
upward; (2) decrease frontal
opening by lowering the
lintel or raising the hearth
(glass doors may help); and
(3) increase the free area
through the damper (ensure
that it opens fully and
without interference).

system
