high carbon monoxide level
I do work for an apartment complex, each apartment has a very old fedders standing pilot furnaces. they were installed in 1971 to 1972. the owner is very stubborn about getting new units and he can still get parts for these dinosaurs.
each apartment has a carbon monoxide detector. one apartment has a high reading and the alarm is sounding. the manager switched alarms with another apartment to make sure it wasn't giving a false reading and I checked it with my tester and is still reads high.
I know some 90+ furnaces have to be adjusted properly but I never saw a problem with a standing pilot system. I looked at the flame and it looks ok. the flame doesn't bounce around like it does with a cracked heat exchanger. It has no chimney. It's direct venting through a pipe outside and that's clear. nothing else in the apartment is gas. there is an electric oven and the gas water heater is in the basement which supplies 16 units.
