Hi all,
I noticed the flue on my Piazzetta pellet fire has a little section that protrudes down over the outlet (about a quarter of the way) where the exhaust/outlet of the pellet fire meets the rest of the flue. The sketch below shows this better than I can explain...
It only overlaps by about 1.5cm – so there's still plenty of airflow underneath, but I was wondering if this kind of design might cause turbulence in the flue and create a little back-pressure or other strange behaviour? (such as intermittent failed lighting or black soot on the glass?). Or would it not really make any difference with such low pressures? Curious to see what others think.
As the flue has been riveted and silicon sealed, it's not that easy for me to open it up and trim away the part that protrudes down...
Cheers, Kim
