    I could not find this in your Q&A section.

    How much distance should be maintained between the exterior sidewall direct vent of a gas fireplace and the nearest operable window?

    (I have heard codes restrict this to reduce the amount of flue gases recirculated into the house thru an open window.)


    The diagram that I have seen most calls for the following:
    12" in the US and Canada from the vent to the open part of the window or door. This should be detailed in the owners manual.
