New Boiler Natural Gas Smell

in Gas Heating
I have a Williamson GSA-100 boiler that was installed about a month ago (natural gas, steam heat). There is a natural gas smell that comes from the boiler mainly when it fires up. The natural gas smell is noticeable in the basement, but not continuous (like when the pilot light is out). There is no smell when the boiler is off. I spoke with the company that installed it and they said there is a gas puff when the boiler fires up and recommend installing something similar to a dryer vent in the boiler room. Previously I had Burnham boiler and did not have this issue. Are the Williamson boilers known for this? Is this a common issue? Thanks.

    There shouldn't be enough gas to smell it, in the basement. It sounds to me like there is a leak at a pipe joint after the gas valve or a burner tube isn't properly seated or is not fully firing. It should be checked by the installer. Better safe than sorry!

    If the installer wants to drag their feet on correcting the problem, you can always call the gas company. They can use their electronic sniffer to locate the source of the gas smell. Just know that they probably won't fix the problem, and they may turn off your gas until the problem is resolved.

    After you make that expensive repair and you still have the same problem, What will you check next?

    and that should get a better response from the installer!

    Post pics of gas burners. I had that once and it turns out that one of the burner tubes were bent.

    I have a WM EG series which is basically identical to what you have and I've never smelled anything from it.

    A leaking pilot tube will do that as well.

    Must be a small leak after the main gas valve could be pilot tubing.

    Once lite, and the draft established, that gas may be drawn out of the basement up the flue pipe.

    Just a note to the OP, I have a boiler about your size and I have spent many hours right next to it when it is starting, stopping and firing, and I have never caught a whiff of NG. I am sensitive to the smell.
