ENGLISH
Special attention must be paid when building fires like this since if the air intake is reduced too
quickly, the fire could smoulder. The wood must be flaming brightly before leaving the fire to
burn.
5.7.4 Burn Cycle Time
The burn cycle time is the period between loading wood on a coal bed and the consumption of
that wood back to a coal bed of the same size. The flaming phase of the fire lasts for roughly
the first half of the burn cycle and the second half is the coal bed phase during which there is
little or no flame.
The burning time expected from this stove, including both phases, will vary depending on a
number of things, such as:
− firebox size,
− the amount of wood loaded,
− the species of wood,
− the wood moisture content,
− the size of the space to be heated,
− the climate zone where the house is, and
− the time of the year.
The table below gives an approximate maximum burn cycle time, based on firebox volume.
Table 1 : Approximate Maximum Burn Cycle Time
FIREBOX VOLUME MAXIMUM BURN CYCLE TIME
<1.5 cubic feet 3 to 5 hours
1.5 c.f. to 2.0 c.f 5 to 6 hours
2.0 c.f. to 2.5 c.f. 6 to 8 hours
2.5 c.f. to 3.0 c.f. 8 to 9 hours
>3.0 c.f. 9 to 10 hours
A longer burning time is not necessarily an indication of efficient operation. It is preferable to
build a smaller fire that will provide three or four hours of heating than to fully load the firebox
for a much longer burn. Shorter burn cycles make it easier to match the heat output of the stove
to heat demand for space.
5.7.5 Logs Orientation
In a relatively square firebox, the wood can be loaded north-south (ends of the logs visible) or
east-west (sides of the logs visible). North-south loads allow more wood to be loaded at the
same time. On the other hand, they break into smaller pieces faster. This kind of load is good
for high output, long lasting fires for cold weather. East-west loads allow a limited amount of
wood since too many logs could cause them to fall on the glass. Placed in a compact way, they
take a long time before breaking down. They are excellent for low-intensity, long-lasting fires in
relatively mild weather.
5.7.6 Carbon Monoxide
When unburned logs remain in the firebox and the flame disappears, go outside and look at the
chimney exit. If there is visible smoke, it means that there is still combustible to burn but that
the fire lacks air to burn properly. In this situation, the CO rate will increase so it is important to
react. Open the door slightly and move the log with a poker. Turn it over and create a passage
for the air below, making a trench with the coal bed. Add small pieces of wood to restart the
combustion.
