TO ACHIEVE CLEAN BURN
This section applies for the burning of dry wood and to broad based long flame path solid fuels.
Take some time to familiarise yourself with the air controls of the stove (diagram 9) to achieve the clean burn state
that these stoves are renowned for.
The air wash is controlled by the lever on the top left hand side of the stove.
When the lever is in the UP POSITION the air wash is closed.
When the lever is in the DOWN POSITION the airwash is fully open.
A) When lighting or refuelling the stove allow it to reach operating temperature every time, before attempting to close
the air wash control lever. The glass will get dirty if the stove body has not reached the optimum
temperature first and clean burn will not be achieved. We recommend that you use a magnetic surface-mounted
thermometer (which can be purchased from your supplier or from ourselves) to achieve this. Place it on the body of
the stove at the front right hand side just above the door hinges.
Regard the bottom ashpit door air slider control like the choke on a car i.e. close them as soon as the stove
is warm.
B) Leave the top air control open for about 20 minutes until the surface temperature of the stove body has reached a
temperature of 250-280
o
C (450-500
o
F), as shown by the thermometer. Slowly close the air wash lever. Although use
of the ashpit door air slider will increase the draw of the fire, prolonged or excessive use of this under draught will
cause dirtying of the glass, and can lead towards excessive over firing of the stove,
therefore reduce under draught as soon as is practical.
C ) When refuelling the stove, first open the top air control to increase the draw of the fire and allow the
chimney to warm up, this will draw any smoke/fumes up the chimney when you open the main door. To maintain the
hot air flow from the front of the stove to the rear, drag any unburnt fuel to the front and add new fuel to the rear. Try
and keep the fuel at least 25mm from the door glass when the door is closed and repeat the
procedure in B . For recommended refuelling intervals see table 1.
Time spent now will reward you and remarkable results should be achieved. This will be even more apparent to you if
you have previously owned a conventionally draughted stove.
It will take a few loadings and firings before you become familiar with the air vents and amount of fuel necessary to
achieve the burning rate you require. Try to load the stove with fuel enough i.e. not too small a load and not too large
a load.
To be avoided at any time is loading the stove up and immediately closing all the air controls.
