Natural Fireplace Maintenance

February 8th, 2013 by admin Leave a reply »

QUESTION:

We have a natural fireplace, not gas. Can you tell us the maintenance we should be doing on our fireplace? What is the maintenance on a gas fireplace? Should we be having our chimney cleaned out by a professional? Is this necessary?

ANSWER:

F005 - Masonry FireplaceFor a typical wood burning fireplace, you should have the chimney cleaned and inspected every several years. The cleaning depends on how often you burn wood. If you burn most weeks, clean the chimney every year. If you burn a few times per year, clean the chimney every few years.

With a gas fireplace the maintenance is limited because the products of combustion are relatively clean. The fireplace logs should not be producing excessive soot and they should be checked along with the chimney flue every couple of years.

With either fireplace, you should also make sure the damper is closing tightly when you are not in use. You should make sure the damper opens fully and latches open when you build the fire. Outside there should be no bird or animal nests in or around the chimney.

For a masonry chimney, the cap should be solid and overhang the structure of the chimney. The structure should be solid without salt stains or surface spalling. For a framed-in metal chimney, it should have a cap that directs water away from the flue with limited rust. The box should be in good condition just like the siding of your home.

With either type of chimney, I think it is important to have a rain cap on the flue. They keep water and animals out of the chimney flue. When in doubt about chimney or fireplace issues, have a professional check it out.
