When the CO test was ran, my father said it was a miracle they both weren't dead from the CO level in the trailer. So, in that, some people do leave stoves on and open to heat small residences for means of heat when the regular heater goes out.

It's all bad, real bad and that's why I brought it up. If homes were air tight and people constantly not moving through the doors there'd be dead bodies everywhere.

Happens more than people know.

With all of this energy conservation and super tight "green" houses, it's no wonder that people feel lousy. You NEED clean fresh air.

My house was built in the 60's. When I feel the occasional cold draft in the winter, I know that I have some fresh air in the house. I'll pay a few dollars more for the gas bill.

If I ever moved into a newer "tight" house, The first thing I would do is install an air to air heat exchanger. They sure are pricey, but worth it, imo. Or just open a window

Im pretty sure theres a nationally acceptable max of around 30,000 input btu to go ventless..When nat or lpg gas is burned without a vent, ALOT of condensation and byproducts swirl around the closed in area..there ok for porches and places that are not airtight..
Id never use one for sure anywhere..or a kerosene heater.

I spent the extra $$ and time to install direct vent gas fireplace and a direct vent stove at cottage..The stove looks great and gives off alot of heat..
The outgoing gases warm the incoming fresh air as its a sealed combustion unit..no worries at all there..

I would never install for profit a ventless unit..But i do hookup gas 4 burner ranges and i think they are right there at 30,000 btu input..
Uninformed customers use the gas range for cooking AND ventfree stoves/fireplaces at same time..bad bad bad
And they dont know what a CO detector is..God watches out for children and fools...i guess
