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.

Check the manual. Some of them are deactivated by being too near some burning objects. They should list the proper way to test your unit.
Good luck, DoN.
OK, I will check the manual.
Thanks.
