    Default Liquid Propane

    I'm being told that combustion air venting for a heater/water heater that uses liquid propane in a closet is not needed ; is this true? if so why?

    Direct vent? Louvered door? Has to get combustion air from somewhere.

    Combustion air needs are the same for natural gas as propane. Someone misunderstood the question or you misunderstood their answer or they are just full of crap.

    As Jim and David have said, it has to get air from somewhere! This is when you ask the person that tells you this to provide the document that cites what they are saying.

    Aside from the requirement for combustion air, you need to insure the closed closet does not become a confined space. LP gas will pool at the bottom of the closet if there is no vent or drain to let it out. If it fills with gas it is a bomb waiting for a spark!

    Exclamation LPG

    FYI-Liquified petroleum gas

    If it uses combustion, it uses air from somewhere. Make and model?

    Keep the fire in the fireplace.

    I suspect you are referring to adding combustion make up air vents. A direct vent appliance does not need combustion make up air vents as it gets all of its combustion air directly from the outside.
