this. When the heater is run when it is rainging outside, humidity from
outside coming in is far worse than what is caused by the heater. The
CO
detector has a "highest level recorded" memory setting. It is still on
zero.

Just for testing purposes, I ran the heater with no ventialation for a
while
and it gave me a headache. When I ran it with the attic door open, I
got no
headache.

That headache suggests to me that the CO detector is not working
properly -- assuming that it still reads zero after the test with no
ventilation.

You probably should test that detector before depending on it.

Good Luck,
DoN.

I think I will set it near the heater and try again.

Thanks.
