Central heating burner questions

    Have a couple of questions regarding a Grant Euroflame 50-90 and Riello setup...

    We had to do a bit of work on it a few days ago (sludged up filter), and were cleaning out the soot from the firing chamber, and noticed a few bits of material that was greyish, and looked like it was a layered substance.

    Is the chamber lined with some sort of material, and how much coverage inside the chamber should there be?

    Is it something we can obtain ourselves and re-line the chamber, or is it a more specialised job? And is it reasonable to expect that some of the lining might be beginning to come away at this stage, 11+ years?

    Also, the setup is about 11-12 years old, is any lining inside likely to contain asbestos?

    Thanks.

    There will be a gasket on the chamber door, and a refractory base in the bottom of the boiler, both may need replacing.
    These would be checked and replaced as required when the boiler is serviced yearly.

    No asbestos.

    I would always recommend having a professional into do this work, as boiler setup is important, incorrect set up and poor seals can easily result in carbon monoxide poisoning.

    Thanks for the info.

    Today we had a closer look, cleaned out the baffles and walls, and vacuumed out the soot, etc.

    The refractory material in the bottom of the unit is actually in pretty good shape, once we could see it properly, it's missing a few small chunks, but it seems to be fairly thick anyway, so we will see what the service guy says about it during the summer. Is it something that is made up wet, and poured into the bottom and allowed to set?

    One thing we did notice and have another question about is in the bottom chamber, where the flame from the burner hits the back wall. Should there be some material here also? It seems like the flame is touching directly to the metal wall/casing at the back of the flame chamber?
