Hello all, I want to put in a wood burner, ive knocked through the fireplace and found the existing flue is in the corner of the fireplace, its not a big fireplace so if im going to get a stove in there the flue will need to go straight up, the lintel looks as though half used to just be a shelf and the original fire place was much narrower above the lintel. there is now a stud wall above the lintel, im planning to connect a new central flue into the existing and then box it back in.
Can I drill through the lintel to create a new flue?.. a series of holes in a circle etc? ive just had a quick go with a hammer drill but its not going to happen, will I need an sds drill to do this, or is this a bad idea and should I be thinking of a new lintel?
thanks
