The fireplace is not burning well

Hello everyone,

I have a problem with our fireplace. The fire in the fireplace regularly dies down even with the fireplace door and window open. So it cannot be due to lack of air. However, it also happens that the fire quickly flares up again. I also find that the fire burns erratically and I can clearly hear the air whistling through the fireplace.

What could be the cause of this?

Thank you very much for the advice.

That is actually unusual. Do you have smoke in the apartment? Or ask the stove or fireplace installer. Maybe there is something to consider during construction in your area.

Hello,
We often have a chimney smell, but I think that is a different topic. We have this smell when the fireplace is burning and I turn on the fan in the bathroom. No window is open. Nevertheless, there is negative pressure in the apartment and air is drawn in through the chimney. That is something I just cannot explain.

Best regards

Hello Nina,

I suspect that the primary air, that is the direct air through the ash grate, is set too high. Now the question arises: Does your fireplace have primary and secondary air?

It is always difficult to give a remote diagnosis, but the fireplace draws too much air.

Please do not use this wood-burning stove anymore, as it is life-threatening. Be sure to call the chimney sweep and explain the problems. Combustion air must be able to flow in and in sufficient quantity. However, the problem here is that the combustion gases are being drawn back. This is a great danger to you and your family.
Best regards

Hello,
It seems the chimney sweep has overlooked quite a bit here. For me, the chimney is not operable like this. So quickly go to the chimney sweep and inform him. Before something worse happens.
