    CO PPM in exaust on Bryant 350MAV

    Question. I ws on a Bryant 350MAV 90% furnace yesterday and the flames looked funny so I took a reading in the exhaust and it was 1392 PPM. Secondary heat exchanger is bad. Roll out switch was not tripped but the burner box was extremely hot. I had my own business in Minnesota and by code you are suppose to red tag furnace. So I called Bryant here in Indiana nd they told me as long a it is not entering into living area I should leave it on for them to have heat. Of course I was shocked about this and felt uncomortable but the other tech said to leave it on for them also. So I left it on even though I was uncomfortable with this. The other tech said since Bryant had a enclosed burner compartment and the inake was vented outside it was ok to leave furnace running.

    Did you use a CO meter in the living space to make sure CO wasn't entering the living space.

    Monday I am telling the other tech and my boss I don't care what the rep said for now on I will go by what my meter tells me and I will shut unit down and explain to homeowner the danger. I think our rep is full of it.

    Is Bryant willing to supply you with a letter stating that 1394 ppm of CO is OK, and the unit is safe to operate? I doubt it.

    I would also have the home owner put in writing the fact that you want to red tag the unit until it is fixed, but they are authorizing you to leave it operating knowing the dangers.

    Even then, who knows what the lawyers would do, if anything happens.
    Instead of learning the tricks of the trade, learn the trade.

    I told the homeowner this and how I felt about this and of course homeowner had no CO detectors in the house. Bryant here in Indiana I am kinda fed up with them. I had a secondary plugged up couple weeks ago and they won't honor the warranty on a plugged secondary unless it is rusted out. They said you should have abulletin about this at your shop which we dobut haven't had time to read this yet. But I will ths weekend.

    If your state doesn't have laws/regs requiring you to disable the furnace. Then turn the switch off. note it on your invoice that you did so. leave a copy of your readings with the invoice. Verbally explain why its unsafe to the customer, and tell them you turned/left the service switch in the off position. note on your invoice that you explained the dangers to the customer, and that you informed them that the power was turned off. get their signature. If they turn it back on later. You have your proof you explained the dangers, and left the furnace turned off.

    I agree. A secondary h/x with the polypropolene failure is the same as a hole or crack in a primary. The unit should be redtagged and the gas and electric turned off. it is our company policy anyway. ALWAYS COVER YOUR ASS!
