    Hi,
    I'm brand new to this forum and I'm here because I just had professionals install a little moe all nighter. Upon starting a fire, with valves open all the way, there is a catenation type of sound and the dial vent in the front puffs out smoke. With the door open, smoke does not come out
    the installer says it's because there is a crack in the stove
    Thoughts?
    Thanks,
    Patty

    Not that we can tell. It's got the tubes on the inside that I cannot see into, but there aren't any visible cracks

    Ok is there a full stainless liner to the top of the chimney or is it just vented into the fireplace flue?

    There is (we have not checked the roof and have to take their word for it) a liner

    Ok well back puffing is usually due to poor draft and or wet wood. If you do have a properly sized full 30'liner you should not have poor draft. What temperatures are you running at?

    it's almost if an reverberation of air pushes the smoke out the valve in the front

    How hight should it be?
    can't get it blazing because we cant open the vent due to the smoke coming out of the valve
    with the front door open, we can get a hotter blaze

    You are smouldering the fire probably due to wet wood it fills the box with smoke which then ignites then fills again. What moisture content is the wood at?

    2 years cut split and covered, it's dry
    the pipe is 6"
    we are only using 3" split wood
    I don't have a way of actually measuring moisture content of pieces
    tmep is up to 500 right now

    Well I don't know without knowing what size or even if you have a full liner or not I really can't give you much more input.

    Thanks for your help .... to recap - Is there a difference between the pipe and a liner? the pipe goes all the way out to the top of the chimney and is capped off, the wood is seasoned two years, it's not wet, it's kept dry and covered

    Well a liner is a stainless pipe. It should be insulated but basically just a pipe.

    Then it doesn't make sense to me. You need to get a good sweep out to diagnose this.

    Stove is huffing which means it's starving for air which stops when you open door. 3" splits sounds small, like a kindling fire which will require lots of air, possibly more than the valve can supply.

    Is this happening throughout the burn, is the spin air valve opening fully? Try starting a smaller fire get the stove and flue to temp then a couple larger sized splits.
