6. Is a vent fan, exhaust hood or central
heating/cooling system stealing combustion
air from your fireplace? If their volume is high
enough, this can cause negative pressure and
an unwanted downdraft – and smoking.
7. Is your wood fuel too wet or unseasoned?
Or does it contain some chemical substance
that causes sputtering, smoking and toxic
fumes?
8.
Figure 5
illustrates the correct height of
your chimney top. It is unlikely that your instal-
lation does not adhere to the installation
instructions. However, if not correct, you
could experience an unusual downdraft. Usu-
ally, the best solution is to increase the chimney
height. This may also be necessary if nearby
trees, adjoining roof lines or a hill is causing a
downdraft condition.
9. Remember, your fireplace has been de-
signed as a supplemental heating device only,
it is not intended to heat your entire home.
2. When lighting your fire, a little smoke may
escape into the room – more likely if the
chimney is cold. To correct this, hold a lighted
newspaper up inside the firebox near the open
flue damper. This will turn around any down-
draft and clear the flue of cold air. As your log
fire burns below, the updraft will improve as
the chimney heats up.
3. Is your fire too far forward? Move it toward
the back with your poker. Keep the fire well
within the confines of your fuel grate.
4. Keep your fire up on the grate and the refrac-
tory below free of excessive ashes. The fire needs
plenty of air movement around the logs.
5. If smoking occurs an hour or two after
lighting the fire, perhaps your well-insulated
house is too airtight and there is scarcely any
way for replacement air to enter and feed the
fire. Check to see if your outside combustion air
kit (if installed) is open. Check outside to ensure
no obstructions are in front of exterior air entry.
Open a window slightly, open doors to one or
two rooms and see if this stops the smoking.
