Hi i wonder if anyone can help me. I have a Trianco Eurostar oil boiler i think its quite old, i did have it serviced 6 months ago when i moved in the heating engineer said it was in good working order. The flue pipe that comes out of the top is about 4" in diameter and goes into a 6" pipe the gap between the two seems to be packed with a kind of cement compound and a lump has fallen out. could anyone tell me if this is flue jointing compound and is it just a case of filling in the hole from where the piece fell out and is it safe to use the boiler before this is done.
It depends on where it is, if its outside or in a out building that has ample ventilation OK, indoors its not a good idea to use it until repaired. The possibility is that flue gas may fall into a living room, this is very likely if as would appear from your text the pipe is mainly outside and uninsulated.
