The Precision Inset (HF357i) Baffle Plate sits at the top of the firebox in your Hi-Flame Precision Inset, redirecting heat and flue gases to maximise combustion efficiency. Over time baffles warp or crack from sustained heat exposure, and fitting a replacement restores proper draw and output. This is a genuine spare part made to the original specification, and fitting is a straightforward job once the stove is cool.
