    I would like to convert my pellet stove to a direct vented gas stove. Currently, the pellet stove vents through a 4 inch flexible pipe traveling up through a masonry flue with interior dimensions of 10 1/4 in. X 6 1/4 in. Will the 46DVA-KMC conversion kit work for this application?
    1 Answers
    This masonry conversion kit will only work if the product literature for the direct vent stove you are considering allows for a masonry conversion using Simpson DuraVent DirectVent Pro.

    I'm trying to vent a Lopi Spirit Propane Direct Vent Stove through my masonry chimney. It has a 6 and 5/8" opening off of the top of the stove but I need to vent it to a 4" masonry chimney. Can I use this product along with a 4" liner in my chimney? Can I use the Dura-Vent DirectVent Pro Horizontal Vent Pipe Termination Kit - For Vent Pipes with a 4-Inch Inner Diameter - 46DVA-KHA? What would you suggest?
    1 Answers
    This item allows you to take advantage of a wide masonry flue for the intake portion of your stove's venting. Your stove would still require a 4" flexible liner for the exhaust portion of the venting. As your masonry flue is only 4" in diameter, it is not wide enough to properly ventilate your Lopi stove. You would need to build in a full venting system independent of your masonry chimney. Or, widen your masonry to accommodate the larger venting of your stove.

    This is what I am looking for but the dimensions are 4 inch by a 6 and 5/8th inch outer dimension. My thimble is only 6 inches inside. Is there a reducer to accommodate from 6 and 5/8" outside to 6 inch, or what other part do I need?
    1 Answers
    Unfortunately, there is not an adapter that is able to size down the outer wall of this series of direct vent pipe to 6 inches. If your clay thimble has a total wall thickness of at least 5/8 of an inch, you could break out the clay thimble to allow for additional clearance.

    Can I vent a Napolean GDS50P into an existing masonry chimney? How does this product (46DVA-KMC) compare to the Co-axial to co-linear venting?Also, the chimney pipe exits out the side of the chimney. Do I need a Tee with Removable Take-off with a band connection?
    1 Answers
    This kit is the preferred method for venting a direct vent stove into a masonry chimney. You would indeed use a 4 inch flexible liner to vent exhaust gases between the transition adapters, while intake air is drawn in around the liner through the chimney. You would not necessarily need a tee to make the turn inside the masonry chimney. Standard direct vent piping could be run up to your chimney thimble, then the transition can be made to the liner. While it will depend on the size of your chimney flue, you should be able to make the 90 degree turn inside the chimney with the liner. Only if the flue liner is very small should a tee be needed.
