Unvented gas logs

Kate Dolan | Posted in General Questions on

I was so excited to get vent free gas logs last year in my two fireplaces. Now I have a film on all my windows and mirrors. I’ve read your posts about vent-free products.

My brother is a firefighter and having a FIT that I’m polluting my home. In 6 months I’ve had 2 serious respiratory infections. (No mystery, right ?)

QUESTIONS: Is there a way to make the vent free logs … vented? They are in the fireplace already — I’m not mechanical at all but it seems it’s doable. I’d hate to loose the logs but better them than me.

Thanks so much.

    What kind of fireplaces are these, and what do you want from the fireplace? Do you want it primarily to provide ambience or heat? I think the recommendation is going to be to get rid of them, but we could perhaps recommend other ways to meet your objectives.

    It's more typical to discuss the appliance in which the flame occurs rather than the "log."

    There are two types of gas-burning space heaters: vented heaters and unvented heaters.

    There are also two types of gas-burning fireplaces: vented fireplaces and unvented fireplaces.

    Presumably, you are creating your gas flames in some type of appliance -- either a space heater or a fireplace. If this appliance is unvented, the solution is to get rid of the unvented appliance and to install a new vented appliance. This is easiest to do if the location is against an exterior wall (so that the vent can penetrate the wall).

    If the location is in the center of the house, there are appliances that vent straight up, through the roof.

    Have a look at some of the new LED fireplace inserts..they provide ambiance, heat if you want it and no emissions in the house... we are in a condo that banned real fires in the existing fireplaces and sealed the flues... a $300 LED insert and some trim made it look real.. it even came with a remote to set the temp and a variety of fire looks and colours... its almost real... particularly after a beer :)
