Question: Re: electrical smell We recently purchased a home with a zero clearance wood burning fireplace.I have to admit that I don't really know much about these units. We have had our first fire in the fireplace and there is an odor much like that with an electric convection heater.Is this normal? I am used to the old masonry fireplaces. Answer: Depends. If the unit is new this will always happen. If it has not been used in a long while, the dust inside the convection jacket will smell. However, after the initial firings it should not smell. If it continues have it checked by a certified sweep or installer.
