For the cleanest burn using wood it is recommended that the primary air control is fully
closed and the secondary air control is opened so the notched marker lines up with the
top of the stove.
Wood burns most efficiently when the air for combustion is supplied
from above the fire bed rather than below. The air supplied above the
fire bed provides the oxygen necessary for the volatile gases (smoke),
given off by the wood as it heats, to combust. This ensures that the
gases are burnt and used to heat the stove instead of being wasted up
the chimney or condensing and forming tarry deposits inside the stove,
in the flue or on the stove glass. Running the stove with the primary air
control open and the secondary air control closed, will provide oxygen
for the wood to burn on the fire bed but will not provide air for the
volatile gases above the fire bed to combust resulting in a smoky
inefficient fire.
ASH REMOVAL
Only remove small amounts of ash from the firebox. When de-ashing, leave 30-40mm
depth of ash in the bottom of the firebox for the best performance.
CORRECT RUNNING TEMPERATURES FOR BURNING
To get the best results from your stove it is recommended that a wood stove thermometer
(available from your stove dealer) be fitted to the flue pipe above the stove, at eye level
if possible. The figures below show the recommended temperature of the flue gases:
115°C – 245°C
The flue gases should be in this temperature band for the safest, most efficient
and most economical operation of your stove.
Below 115°C
This is below the condensation point of wood gases and may cause the build-up
of tar in the chimney, dirty the stove glass and result in the inefficient burning
of the fuel.
Above 245°C
Too hot. Heat will be wasted up the chimney. Excess heat may damage the stove
or ignite any existing accumulation of tar resulting in a chimney fire.
EXTENDED BURNING
Loading a large amount of wood into the stove all at once will reduce the temperature
inside the stove. If the temperature is too low, the gases given off from the wood will be
too low to combust resulting in a lot of smoke covering the inside of the stove, including
the glass, with soot. To combat this problem it is a good idea to increase the temperature
of the stove before loading by further opening the air inlets. Load the wood and leave the
air controls open until the moisture is driven out of the wood and the stove is back up to
an efficient operating temperature. The air inlets can then be reduced to hold the
temperature of the stove. Loading the stove little and often will help keep the stove
temperature steady. When loading wood, make sure that the end grain of the wood in
the stove is pointing away from the glass, otherwise the moisture and gases coming from
the end grain of the wood will dirty the glass.
