being wasted up the chimney or condensing and forming tarry de-
posits inside the stove, the flue pipe or on the door glass. Running
the stove with only the bottom air control open in a Vesta stove
does not supply air to the base of the fire but adds oxygen to the top
of the fire at the back of the stove. This helps to draw the fire into
the back of the stove away from the glass.
Slow woodburning
To slow the burning rate and output from the stove reduce the air
entering the stove via the air controls. The fire must be well estab-
lished and the stove hot before a minimum combustion rate is
attempted. Note that if the air supply is restricted too much the fire
will burn dirty and inefficiently. Slow overnight burning is not ad-
vised for this reason.
Ventilation
The stove requires an adequate air supply for successful operation
(see Installation section of these instructions for more details). En-
sure that air bricks or grilles supplied for this purpose are not
blocked. Be aware that the operation of exhaust fans or other appli-
ances that compete for ventilation in the vicinity may affect the per-
formance of the stove.
Running temperature
To get the best results from your stove it is recommended that a
wood stove thermometer be fitted to the flue pipe just above the
stove. Most thermometers are magnetic and if attached to the sin-
gle wall flue pipe just above your stove will give a good indication of
the flue gas temperatures.
Flue thermometers are available from www.vestastoves.co.uk
