When my gas boiler is on and it's quite windy outside the flames are
affected by the wind quite a bit - as if it's windy where the flames
are yet as its an old type the inlet air comes from the house and the
outlet is a stack running from the ground floor to the roof guttering
line and has no faults / holes etc I can see and looks in good
condition and has a berathing type cap on the top. What's going on?
I have a CO monitor and the level increases (still within safe limits)
when this occurrs so obviously it's not burning properly.....
