FRESH AIR INPUT & RETURN OF SMOKE
Evolution stove installed properly should not produce smoke in the house. If the stove continues to
produce smoke, it will probably be for one of the following reasons:
1)
The chimney’s external installation is defective or incorrect, engaging in problems of return of air
and, consequently, of difficult lightings.
2)
The heating of the chimney is insufficient. Not to forget that the hotter the stove is, the more the
chimneys will intake smoke.
3)
The doors or the air register input were closed again too quickly. The contribution of air is
essential with the maintenance of combustion
.
4)
If the area is too airtight or the house presents a negative pressure and it does not have an
external air intake, the contribution of air to the stove will be more difficult than normal. Temporarily
open a window near to the stove to increase it.
5)
Any ventilator (cook top exhaust fan, bathroom ventilator, central vacuum cleaner or drier) that
aspires the air towards outside can create a negative pressure in the house. Close them; open a
window near the stove to regulate this problem.
6)
Wet wood releases more smoke while burning than seasoned wood. The wetter the wood is, the
less it releases heat and the more it produces creosote. If the wood burnt is very wet, inspect the
chimney every month that the stove is in use.
7)
Make sure that the chimney is reasonably clean and free of any obstruction.
8)
Check if the chimney is sufficiently high: minimum of
914 mm (3pi.)
above its junction with the
roof
(see figure page 7)
. If not, add additional lengths of duct which will increase the chimney’s
draft and will reduce the tendency of smoke return.
9)
The chimneys joined with an external wall (see page 10 drawings of right-hand side) without
coating often present problems. Open a window near the stove, heat the chimney while presenting
paper in the shape of torch in the opening or by crumpling several newspaper’s pages in the stove,
to light at
3
or
4
different places, hold the door half open for a more active fire in the stove, during
this time, the chimney will be heated more quickly.
10)
Always remove the surplus of ashes before lighting a fire. Maintain a thickness of ashes of
25
,
4 mm (1in.)
for optimized combustion and to maximize the duration of fire.
