Hi.
I have a problem with my draught regulator KW Z150 on my Baxi / Brötje HVK 50. The chimney is placed outside the building.
The draught regulator is leaking a lot of smoke when I starting the fire.
The problem disappears when the EGT is high enough and draught becomes normal.
Is the problem solved if I change to a draught regulator with better seal? Or what can I do?
