Re: Vent Free Gase Fireplace insert
If they weren't safe, they wouldn't sell them. Just like plastic pipes, genetically modified corn, milk from cows treated with RBST, granulated sugar, antibacterial soap, and vaccines.
Here's the propaganda page for the Vent Free Gas Products Association.
Personally, I think they are safe, but you must be aware of several things:
- They produce a significant amount of water vapor. You must be prepared to deal with the excess moisture in the air.
- When used in a small space, they can consume the oxygen in the room. Only purchase one with a low-oxygen sensor. Also, you may want to provide a source for fresh air.
- Even though they produce almost no carbon monoxide, you should not operate one without also having a working carbon monoxide detector, in case something goes horribly wrong.
- Besides water vapor, the other major byproduct of combustion is carbon dioxide. Depending on the purity of the fuel source, additional byproducts may include nitrogen and sulfur compounds and other trace complex gases. These additional byproducts are minimal.
And one last point: gas cooktops, ovens, and ranges are common and are not direct vented.

The "Senior Member" designation under my name doesn't mean I know a lot, it just means I talk a lot.I've been a DIYer since I was 12 (thanks, Dad!). I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
