Recently fitted a multi fuel stove. Correctly installed etc by a certified fitter and had the chimney cleaned first. New burn smell was horrendous first couple of days then subsided only to be replaced by a new smell. When the stove is on the whole house smells of burning, not smokey as it doesn’t set off the carbon monoxide alarm or smoke alarms just pure burning/singeing smell. Fitter came out and did smoke test but stove seemed fine but the company in question replaced it with a new stove. Refitted, resealed all flus etc but a few days in and the smell is as bad as ever. Not just as bad when burning smokeless coal but wood is horrendous. The draw from the stove seems fine and the heat is amazing - just can’t enjoy it because of the smell! Help please!
