SMOKE IN THE FURNACE ROOM
This condition is usually caused because smoke
is not being drawn up through the chimney.
Other causes could be a failed (firebox) heat
exchanger. Check with your qualified furnace
service provider.
Chimney causes
:
1. Fresh air for combustion
must
be supplied to
the furnace room.
2. Cold chimney. Warm air rises and cool air falls.
Outside chimneys are cold, which can cause
downdrafts until the chimney heats up. This
usually happens in the spring and fall of the
year when outdoor temperatures are mild.
These temperatures do not produce enough
heat to warm the chimney up.
3. Chimney not tall enough. It must terminate at
least 2 feet above the peak of the roof.
4. A downdraft can occur when the wind blows.
This happens when your home is in a valley or
high trees are near your home. Also, if your
house is on the east side of a hill or mountain.
See Fig. 45
One solution is to add a chimney cap with a
weather vane. This often will turn a downdraft
into an updraft. Another solution is to add
height to your chimney. Another solution is to
add a power venter to the smoke pipe. The
power venter operates when the thermostat is
calling for wood heat.
5. The barometric draft regulator must be set at
-.03” WC (Water Column). If set less, the
chimney may not draw. If set higher, the wood
fire may draw too much combustion air. This
causes the room temperature to exceed the
thermostat setting.
