I aware of all of this, I was asking BKs input from a manufacturers standpoint.
The reason ZC manufactures don’t allow it is because they’ve simply never tested for it. Why would they? There’s no money in it, they sell fireplaces, not inserts...
I’m curious. If almost no pre-fabs allow for inserts to be installed, or allow it as long no modifications are done, (which is pretty much impossible) why would BK put the time and money into testing to make it ZC approved?
I’m not exactly sure what’s got you stuck. It sounds as if you are to the point that you can see the combustion box, but can’t remove it.? You will need to remove the entire damper frame. First remove the rear heat shield, then you will see the bolts on both sides that hold it on.
I just opened the picture. That’s no good! The fit and finish has really been bad for a while now on hearthstones. Definitely get the dealer involved with this one. Where else is it not sealed well? That’s what I’d want to know.
Make absolutely sure the ashpan is pushed all the way in. It will slide in easily, once it stops it requires a solid push to seat it fully. This pan is just a pressure fit, so being seated completely is just as important as the gasket. Make sure the ashdump dial is also in the closed position.
That looks to be sealed up pretty well, not sure how much a block off plate will increase efficiency?
You most likely need some work done to the chimney crown. Sometimes it just needs sealed rather than replaced. Hopefully it’s repairable. Can you get a picture of the top of your chimney by chance?
Lopi, Travis ind, Avalon, Fireplace Extradonaire are all the same company. Lately they’ve done some simplification. Eliminating Avalon is one thing they did. With so many lines in the different brands it was confusing. Avalon and FPX were both established companies that Travis Ind. bought up.
