Woodfire Passiv, Operation And Installation Manual

At that point close the primary control and leave the secondary air and flue damper
to facilitate the combustion.
• It is recommended that the secondary air regulator is kept fully open in order for the
“glass cleaning” to be most efficient, and to avoid the glass “fogging”.
•
Use the amount of fuel you place in the stove to regulate the temperature.
•
To burn at the nominal output, the stove requires refuelling every 45-50mins with
approximately 2.5kg of wood logs.
• When adding larger wood it is good practice to put in a couple of smaller bits first as
the larger logs then light faster, so producing less smoke. When adding wood, the
primary air control and flue damper must always be open, and left open until the
new logs have caught fire. At that point close the primary control and leave the
secondary air and flue damper to facilitate the combustion.
• THE STOVE SHOULD NEVER BE FILLED EXCESSIVELY. EXCESSIVE
AMOUNTS OF WOOD OR AIR FOR COMBUSTION CAN CAUSE OVERHEATING
AND DAMAGE THE STOVE.
v. Controlling the heat output
The heat output from a stove is controlled by the amount of fuel that is put into it, NOT by
opening or closing the air control.
The air control lever is there to enable the user to establish the optimum burn.
Closing the air control lever too much can lead to an incomplete combustion. In addition to
wasting fuel and creating unnecessary pollution it also risks an explosive ignition of the
flue gases.
Opening the air control lever too much can result in the stove overheating and can risk
damaging the appliance.
The performance of your stove is influenced by the chimney draught. Depending on the
length and cross section of the chimney, as well as the weather or wind, the chimney
draught changes. The control lever allows small adjustments to compensate for a stronger
or weaker draught.
If an AirSmart controller is fitted then many aspects of the proper control of the burn rate
of the stove are automated.
