    Is there a top-mounted damper that works with a zero clearance flue pipe that seals the flue as well as the vented air space around the inside flue pipe?
    1 Answer
    There isn't because the space between the inner and outer pipe must remain open with any air cooled chimney system.

    I am looking to replace my fireplace damper. My current damper measures 5 inches wide and most of the ones I have found online are 7 inches. Any suggestions? Can I use a 7 inch one or do I need to keep looking for 5-inch?
    1 Answer
    A 7" damper plate likely wouldn't work because it wouldn't have the properly sized hinges to hang onto your space.

    I have a 10 x 13 inch OD oval shaped flue on my woodburning fireplace chimney. I would like to put a chimney top damper on it to prevent cold air from entering my home. Do you have such a device?
    1 Answer
    With your measurements, I would suggest the Lyemance 12 in. x 16 in. Energy-Saving Damper, which can fit a 10" x 13" flue.

    Are there any electric dampers for gas logs designed with shielded wiring harnesses that can be ran through the chimney pipe instead of trying to feed wire through walls, etc?
    1 Answer
    We are not aware of any product matching this description. If you are installing vented gas logs in a masonry or prefabricated wood burning fireplace, you should remove or affix the damper open and not use any top-sealing damper system of any kind.

    I read that a lock top damper should not be used in gas log fireplaces. Why? Is that a requirement or a recommendation?
    1 Answer
    This is because a damper should never be used with a gas log set, as the house will fill with carbon monoxide if the set is turned on but the damper is accidentally left shut. All vented log sets come with a damper clamp to make sure that any operational damper is left open at all times.

    We have a missing damper plate in our fireplace. The actual opening measures 28 and 13/16" x 5 3/4". I assume we'd need something a bit longer on both measures, right? Do you have a replacement plate that might fit?
    1 Answer
    The Vestal Cast Iron Fireplace Damper Plate - For 36 Inch Dampers measures 7" D x 28 3/8" W, but please note that this product is a replacement damper plate for Vestal dampers and may not fit properly with your damper.

    How do you determine what size damper you need? Can a novice replace the handle?
    1 Answer
    The damper throat should be sized to the width of the fireplace opening. If the opening is sized between the castings available, it should be sized to the closest casting step. The handle itself is usually simple to replace. Most models simply have a drive pin holding the handle in place, but it differs from design to design.
