    In between each section if looking at it sideways, the cement seals are chipping away. Flame can be seen from outside ,in. Can these seals be re-sealed?

    Luckily you stopped using that boiler, as the gaps in between the sections could give off a lot of carbon monoxide into the building, with deadly results.

    Have a look at the Smith website, and although, your model may not be listed, a more modern one will. In the instruction manual, it will describe how the sections are sealed, and what sort of rope-like material to use. The sections may have to be separated in order to make a perfect, and SAFE seal.--NBC

    Yes they were very lucky. The original service call was for the wife having headaches and getting sick. The customer contacted the gas company and they came to shut down the boiler. I arrived a day later to check the boiler. I had draft coming down the chimney into the house through a back draft damper. The customer had left a whole house exhaust fan on for 2 days. No spill switch on the damper. Worst of all the carbon monoxide detector had failed and did not alert the homeowners. Pulled the boiler apart and added these gaps to the list.

    Thanks for the reply. I already contacted H.B. Smith tech support, waiting on a call back. My friend use to assemble these boilers back in the day in Westfield, M.A. He also stated that they use to use a gasket type rope and tighten the sections to a specified torque and cement over. He could not remember specifically how it was done, but was appreciative of the photos and memories.

    What model is that Smith?

    we sometimes drive Kaowool rope into leaks like that and cover it with red hi-temp silicone.

    That looks like a Carlin gas burner. These should run with little or no CO. Be sure to test it with a digital analyzer when you put it back together to make sure it's burning properly.

    Thanks for the reply. H.B. smith recommended the same. Install Kaowoll Rope, after cleaning with wire brush, then cement over with high temp cement. It is a Carlin G3B Conversion Burner. I believe they want the O2 at 4% with an analyzer. We are lucky enough to have Carlin local in East Longmeadow M.A. There technical support is amazing and they really help the technician in the field. Any information you would need on burner or in the field they go above and beyond to help.

    Burner Collar burning up

    The collar on the Gordon Platt burner going into the boiler burns up or distorts after about 2 years. What is going on? How can I stop this?

    It would prob...

    be best to start a new thread. Not super familiar / the model but I would guess that the burner was inserted too deep into the chamber.

    Have you done a combustion analysis on burner when installed?
