    Default Furnace inspection

    I inspected a furnace where one of the burners did not work. It was a 12 year old furnace, I did not see any rust or corrosion. The flame on the other three burners looked fine. What could cause this to happen. I'd like to give a knowledgeable answer next time.

    Clogged orifice is one thing.

    Did it have a sediment trap?

    Thanks Jerry, It did have a trap but the pipe came in horizontally with the trap t-ing off it.

    You mean like this: gas in horizontally -> ----teedown-----> gas out horizontally?

    Those are not allowed because the debris, which is intended to be caught in the sediment trap leg, just blows right over the sediment leg

    .
    To be precise, it was like this, gas comes down vertically, then 90 degree turn horizontally for 2-3 inches then sediment teedown then 2-3inches horizontally then 90 degree left turn into furnace. Why? I don't know. Still wrong. I called for a HVAC guy to look at it. Thanks for the help.
