no-vent gas fireplace?


not sure if this goes in HVAC or not, was just at Lowes looking at the nice wood mantel type electric fireplaces they have as something to put in the basement, and saw gas ones... listed as no vent fireplaces for LP and Nat Gas... how does this work with no vent? wouldn't that be a CO risk? just curious on how they can get away without venting a gas one

These units are equipped with an oxygen sensor that will shut the appliance off if the O2 in the room falls below a safe level. Anything with a flame requires Oxygen (combustion air) and it has to come from somewhere. It's still best to operate the heater with a window cracked, but that will, of course reduce the effectiveness of the appliance.

Also, if you or anyone in your family have athsma or any other respiratory issues, you should not use a ventless fireplace or heater.

Sounds dangerous to me. Apparently they are not allowed in Canada and parts of the US due to safety concerns.

I had one and replaced it with electric just to look at.

It heated the room but it always smelled and it shut off on the O sensor all the time.... I would never have one again.

Maybe other people have been happy with their's.
