can anyone explain the thinking behind taking out the grate whilst burning wood? the stove in question is a firefox 5, not the cheapest nor the most expensive. i’d fitted it in the old place (rented) without lining the chimney where it worked fine, now however it is fitted in the new house, (ours) with liner and vermiculite round the liner, all good and proper. the thing is, it burns a lot quicker now, ie the flames move faster, is this because the chimney is nearly twice as tall or something else? i initially thought the fire rope had degraded but it all looks good. will it burn slower with the grate out? will my wood disappear too quick? will i die? thanks in advance and sorry if its been done before
