    Here is an article by Jim Bergmann on combustion testing. Page 27 discusses a three part test that is recommended, and it includes a visual inspection. On page 29, he states the following:

    CAUTION: Using the word POTENTIAL is very important. If the technician tells a
    customer that they will get CO poisoning, or that they are going to get sick, they can be
    accused of trying to scare the customer.
    D. Explain the potential health risk:
    1. The defective heat exchanger is allowing the flue gases to enter the
    home/building.
    2. If poor combustion takes place, there is the potential to allow Carbon
    Monoxide into the structure.
    3. Carbon Monoxide is a deadly gas. It is colorless, odorless, and
    displaces Oxygen in the blood stream. High levels of Carbon
    Monoxide can cause brain damage and/or death.
    4. Ask the customer if you can shut down the furnace for their safety.
    Open the safety disconnect at the furnace. Record this request on
    your service invoice.

    Lots of good advice there. When shutting down an appliance I suppose local codes and laws may come into it but personally I gently but firmly tell the homeowner I am doing it and I usually do it in two ways. Electric and gas if it is in the winter. If it is standing pilot depending on the situation it may simply be turning the gas valve to pilot if I don't do it at the gascock. They always sign the invoice and if they decide to reverse it they have to take two steps to do so. So it cannot be an accident to turn it back on. Of course it is tagged also.

    That opinion is moronic. Lots of cracks don't show up on combustion checks. Should always visually check and perform combustion check,

    I like the companies that come up with new wording to baffle the customer into buying a new system.

    As one moron to another... Ditto.
    A people who would exchange liberty for apparent safety, will deserve neither and lose both.
