    Oil to gas

    Anyone have experience converting a Smith boiler from oil to a gas burner.

    I have a customer who has a newer oil fired boiler and gas is coming down her street and wants to convert to gas.

    I hate to rip out the newer boiler and put in a gas boiler.

    Wondering how involved it is and if there are any issues.
    Can someone please explain to me -
    Why is there never enough time to do it right the first time, but plenty of time to do it twice?

    Call either/and/or Beckett or Carlin and talk to their tech dept. In the case with Carlin, they will tell you if they fired a gas power burner in that boiler, and all the settings-which burner, gas pressure, orafice size, etc.
    Also with Carlin, the rep for your territory, if you have some flexibility, may come out and fire it up with you. Just make sure you have your manometer and your analyzer.
    What's the model number of the boiler?

    If I do a job in 30 minutes it's because I spent 30 years learning how to do that in 30 minutes. You owe me for the years, not the minutes.

    Keep in mind that boiler was certified for burning oil. Converting to gas changes all that.

    Install a new gas fired boiler.

    additionally, oil has many more btus than gas. it's hotter, faster. that boiler will condense for a long time before it heats up appropriately on gas. It's going to make a mess and fail prematurely.

    tear it out and put in a gas boiler.

    I am waiting for the customer to get back to me on the model number. The tag on the boiler was warn off. She said she has the paperwork on it somewhere.
    Can someone please explain to me -

    That's I I was thinking.

    If the new gas burner is rated at 100k BTU what would be different than an oil burner rated at 100k? A lot of commercial boilers are dual fuel fired with no issues.

    I used to do them all the time. Gas gun to replace the oil gun. You will want to clean the boiler and the chimney VERY well. And technically I think the chimney has to be lined with stainless - check your local code on that one..
