co in furnace

A clogged flue for a boiler will fill a house with CO just the same as a furnace.

    co in furnace

    A friend just called. Said she was hospitalized for CO from a furnace that is a year old. Guessing that the flue pipes are clear - what would cause a 1 year old heat exchanger to crack? Of course all equipment is red taged and shut off.

    Might not be the

    heat exchanger at all, in fact it might not be the furnace.

    Untill someone qualified gets in there and tests everything, you will never know for sure.

    she is fine. She says brand name is Goodman.

    Gas is off by gas company. Plumbing inspector is looking for plumber who did the job. And that plumber is not answering any phone calls. He has 5k of a 9k bid. There is another one of these furnaces sitting on the floor that he is supposed to install. Homeowner is wondering how good these furnace brands are. Homeowner is using space heaters.

    I will stay with my boilers. I do not like the idea of a heat exchanger leaking fumes into heating ducts.

    Goodman is

    a dependable meat and potato product. With rollout switches and the blower fan creating a postive pressure in the duct system. Prehaps a clogged flue-Still I would like to see the Fire Marshall's report as well as goodman's findings of what happened. Before condeming the furnace J.Lockard

    furnace is always blamed

    Following a training class on CO I tested my home furnace and hot water heater both producing 16 to 18 PPM. Then I lit off my oven and the chimney on that produced 47 ppm.

    Researching a bit and I find CO is from incomplete combustion. A cracked heat exchanger can allow the fan air to mix with combustion air and change to high co.

    A smoke test can help confirm problem is furnace.

    Prayers for your friend and maby a good co detector for her stocking

    I realize that assumptions are bad, but I seriously doubt there is a problem with the furnace itself.
    Installation is a different issue. What does the red tag say?
    I hope the space heaters are electric with no extension cords.
