What does a properly functioning gas furnace do that causes health problems?
Not much, a blue flame introduces moisture into the air. Which is better habitat for mold.....thus we have dehumidifiers and AC.
Now of course a yellow flame is a dirty flame with hydrocarbons and not what a properly functioning gas appliance will produce.
This is why gas appliances need check ups now and then. And city codes now require adequate make-up air as to not create negative pressure in the home. With Negative pressure, the appliance will not vent out properly.
Gas appliances are tested to safety standards of emissions inside and outside the home/building.
With work done properly, and an inspector that does their job, all should go well.
A hack car mechanic might make a shady exhaust repair to- not the fault of the manufacturer.
