Question:

Why do the c.m. detectors go off when we turn off the gas supply to our central heater?

We bought an older home that had been completely gutted and restored, but the heating system is still a little primitive (we have to manually turn on the gas supply when we use it). When we turn the heater gas off, our carbon monoxide detectors go off and I end up opening the windows b/c I'm paranoid, and that defeats the purpose of using the heater in the first place. Should we continue to use the heater as is, or is there a leak somewhere that we should be worried about?? Thanks!
