Four years ago I bought a Supra wood burning stove, model HF 3950, on eBay. I installed it myself; connected the rear flue to the chimney tube and it was done. There has always been one problem: it refuses to run gently with the damper pushed in. No way can I have it ticking over all night. Searching this forum led me to “baffle plate”. I think I have one of those! It sits at the top of the combustion chamber and slopes down, from the top of the front to the rear. I note that there are, on each side of the fire box, projections on which, maybe, the plate could sit? One post mentioned “horizontal baffle plate”…. Advice and guidance will be most welcome! Thanks.
