    Gas Log Question

    I'm planning on installing a gas fireplace log in to a Superior wood fireplace that is prepped for a gas log. I would like to get some heat out of the fireplace and I read that a vent-free unit would do that. But vent free supposedly produces an odor. My fireplace has a capability of bringing in outside air thru a vent controlled by a push/pull lever by the left side of the glass window. Will having this vent open help prevent the odor and make the fireplace more efficient?

    You have a vented fireplace, why not a non vent free logset?

    Vent "free" just means the products of combustion including copious moisture are vented into the living space....

    Yes, I know a vented unit would be the logical way to go. But never having had a gas log before I thought the heat would just all go to the flue while my understanding is as vent free unit would give out heat (with the flue damper closed). That is why I am asking the experts.

    Vent free is a euphemism for “my house is a chimney.”
    Do you heat your garage by running the car in it?

    In case I’ve been too subtle, I disapprove of ventless heaters.

    Too = also. To = expressing motion. Two = 2
    Then = after that, next. Than = indicates a comparison.

    You can't have a fire in your living room with no vent and not have an odor.
    Vent free= bad idea. If you want heat look into a direct vent gas insert. A lot more money but worth it

    Least case issue with "Vent free" is you get a TON of moisture in the home... Might be a good thing if you have a drafty old victorian. But, if you have a modern relatively tight home, expect a lot of condensation on the windows, wood rot, and mold.

    I like the Petersen real fire logs on a sand pan. Looks like the real thing. If your firebox is glass door and relatively airtight, you should get some heat out of it.
