    Default direct vent fireplace

    On Modern gas fireplaces which have a realistic looking stack of logs that surround the burner and appear to be log fireplaces, but burn propane or natural gas, how are these written up in report as far as chimney sections and fireplace section of report( due to fact you cant open and look up inside them) , are these called direct vent systems?

    if 'ventless'

    "You home has a ventless gas log set fireplace. Please do a good bit or research on this item in your home before sustained use. More info (a start) can be found here http://www.askthebuilder.com/B96_Gas_Fireplaces_and_Ventless_Gas_Fireplaces.sht ml"

    Direct vented fireplaces are (at least are) 'vented' to the homes exterior - normally directly behind the enclosure.

    Absolutely NOT.

    You've taken a stock photo from an internet site tagged "1190261214_MonessenVentlessGasInsert-LP_DISRoomScene-opt2.jpg"

    Ventless does NOT equate to "direct vent"!

    Logsets do not equal "inserts" nor "fireplaces".

    Direct vent does not equal UNvented or ventLESS!!!

    An insert designed to be installed within a fireplace is not a fireplace.
    A logset is not a fireplace.

    A direct vented appliance takes all its combustion and dillution air from the outdoors and deposts all of the flue gas outdoors (defined in the various gas codes and mechanical codes). Ventless, vent-free, unvented, implies the opposite.

    A F.I.R.E. certified professional, a Hearth professional, possibly a sweep, might be consulted. Perhaps taking a CE course yourself. I believe Dale Feb has a one-day course specifically for HIs in California which covers how to identify what is actually present and covers the distinctions with differences on same - and the various listing requirements, such as flame sensors/gas shut offs, oxygen depletion sensors, etc.

    You apparently "borrowed" the photo from this site: Monessen Ventless Gas Insert - LP - Ventless-Gas-Logs.com I've posted the larger version of the same "borrowed" photo.

    Monessen is here: Monessen - Fire For Your Imagination

    Toney,

    A direct vent appliance should have a double pipe that exits the building. The hot air is exhautsed through the innner pipe and the cooler combustion air is deliverd through the outer pipe.
