    Hi All,

    I just had a quick question about the size of the job to replace the front gasket on my boiler.
    The sweating shouldn't be an issue for me, but I am a little worried about draining the boiler.
    Also the construction of the internals after the plate is removed concerns me, I am not sure what to expect
    from the thermostat, and how the front plate will actually remove. So I was hoping that someone with
    experience could tell me whether I can DYI this, or if I should leave it for a pro.

    The boiler is a:
    Trianco Heatmaker
    Serial: 1093-1199
    Model: DBC-85

    Are there torque specs for the plate?

    Possibly the cause of the failure was over tightening?

    The gasket from the side, looks water logged:

    Right side, not leaking:


    Thanks in advance!

    Can't answer your question, but I had a Trianco Heatmaker (different model), and finally replaced it because it was so much of a pain to keep running. It was the Heatmaker II, with the domestic hot water built in.

    Yeah, I am getting that feeling that it might need more maintenance than it's worth. I need to finish the season out with it, and I think it will make it, but if it was a 4-6 hour job I would probably do it. Anyway, thanks for the input!

    Well it turns out it should be fine for the rest of the season. I was told to just tighten it up, and it will last, but I should have someone out to work on it once we are not longer heating.
