Problem Description Can Occur when.. Possible Solutions
Tall trees surrounding the
building
It doesn’t take much to
affect the draft. A tall tree in
the vicinity of the chimney
can create turbulence that,
at times, may cause spillage
in the heating appliance
served by the chimney.
A problem like this could
literally have been grow-
ing over the years. It is not
uncommon that a replace
that has been working well
for years suddenly
experiences draft problems
due to trees growing around
the building.
• Trees are growing and
getting taller over the years
• Raise the chimney
• Cut down trees
• Install a mechanical draft
system
There is a taller building
next door
Just like a tree, the
neighboring building can
cause similar problems.
It may be a taller building
that affects the wind ow
patterns and cause ow
reversal in the chimney.
• New building is
constructed on the
neighboring lot.
• Raise the chimney
• Install a mechanical draft
system
The building is located in
a valley or surrounded by
taller buildings
A building in a valley can
nd itself in a low pressure
area (inversion) which can
adversely affect the draft.
Inversions are common in
hilly or mountainous areas.
A building surrounded by
taller buildings can
experience similar
problems.
• Install a mechanical draft
system
