AO Smith XCV 50 300 & Carbon Monoxide help!

HenryT Member Posts: 128
Hi Everyone.

A contractor just installed a 50 gallon gas water heater. He claims that the exhaust is clogged and that may cause the pilot to shut off.  He said if the pilot lights goes out, its due to carbon monoxide presence and he should not be responsible for that.

My concern is the carbon monoxide.  I have a  detector and and its not picking any up. Can a clog exhause cause pilot light to shut off?

    You have a potentially deadly and dangerous situation! I don't know how a contractor could leave an appliance turned on with the vent in this condition. He is very much responsible and should not be trusted with your safety.

    Turn it off and have your gas supplier check it immediately.

    I repeat: Turn it off! And call your gas company.

    Carbon Monoxide Levels:


    If a room held 10,000 ping pong balls, and 4 of those balls were and represented CO, it would kill you. There is no safe level of Carbon Monoxide, ever.

    CO blocks the ability of blood hemoglobin to uptake oxygen. One hour of exposure to CO can take up to 10 hours to get it put of your system. While active in your blood, Oxygen can not get into the blood stream to be used by cells.

    As far as your new water heater, in Massachusetts, the flue is supposed to be inspected and lined if needed. That this installer installed this gas heater and left it the way he did makes me wonder about his license status or what the AHJ has to say about these installs.

    It's guys like that that give the rest of us a bad name.

    Don't Listen to This Whack Job aka Pook


    I don't know what your problem is, but advising someone to do something that is potentially lethal when they come to this site seeking expert advise crosses way over the line.

    I think it's time to ask Dan to remove this clown.

    Pook is so far off-base he isn't even on the field.

    HenryT, try the Find a Contractor page of this site to locate someone who knows their business. Then talk to your lawyer to get your money back from the original contractor. This is unconscionable.

    Thanks for your comments Steamhead, Ice Sailor and Ironman.

    I have contacted the gas co to do a CO test and will get the installer back in depending on results.
