FRESH AIR INTAKE & BACK DRAFTING
Diamond wood 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 close to the stove to increase it.
.
5) Any ventilator (cook top exhaust fan, bathroom's ventilator, central vacuum cleaner or drier)
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 the seasoned wood. The wetter 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) Ensure yourself 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 pulling of the
chimney and will reduce the tendency to the return of smoke
9) The chimneys joined with an external wall (see page 11 drawings of right-hand side) without
coating often present problems. Open a window near to 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 (1po.) for optimized combustion and to maximize the duration of fire.
