4.0 TROUBLESHOOTING

3.6 - After Use & Maintaining Perfect Burn Cont.
Combustible remains are deposited in the appliance, the flue and chimney during use. This happens
increasingly if you use wet or treated wood or fuel that is not allowed. The possible overload of the stove or
restrain of the fire can contribute to this also. It is rare that the deposits catch fire due to the lack of regular
cleaning. However, this can be noticed from the black smoke flowing out of the chimney, the rise of the
temperature of the chimney wall and the increased draught that can result in a whistling sound.
In case of chimney fire, call the fire brigade and close all air regulators and outlets. Do not spray or pour
water in the chimney in any case because it can lead to gas explosion. Remove all combustible, heat
sensitive materials from the environment of the chimney, even in the attic.

4.1 - General Troubleshooting

The condition of proper operation of the stove is the appropriate chimney draught (feed pressure). This is
considerably dependant on the temperature of the outer environment. In case of higher outer temperature
(above 15oC) feed pressure can considerably fall and it can disturb proper operation.
