Q: Our house was built around 1940; the fireplace is original; and we installed forced-air gas heating about 10 years ago. We haven’t had the fireplace or furnace inspected. What do you guys recommend to get the fireplace and the furnace ready for winter?
A: Regular inspection and servicing of fireplaces and furnaces adds to comfort, makes them more economical, and most important, keeps them safe. Regular inspections can prevent a deadly house fire or the introduction of a silent killer: carbon monoxide.
Here’s our checklist to keep you cozy and safe during the winter months:
1. Inspection by a certified chimney sweep is a must. For heavy use, the chimney should be inspected and cleaned annually. Go up to five years if the fireplace is used only occasionally. The sweep should inspect for proper operation of the damper and for cracks in the flue liner, as well as sweeping the flue to remove creosote and other combustion byproducts.
2. Close the damper when the fireplace isn’t in use.
3. Install a chimney cap if you don’t already have one. You don’t want creatures building their nest in your flue.
4. When starting a fire, "prime" the flue by holding lighted newspaper at the back wall of the firebox to start the warm air rising.
5. Burn aged, dry hardwood if possible. Fir or pine burns hot and deposits creosote in the chimney. Don’t burn construction debris. It may contain toxic chemicals that will vaporize in the fire and could enter the living space.
6. Do not clean out the fireplace when the ashes are still hot. And dispose of the ashes in a place where wayward embers won’t start a fire.
Fireplace with gas starter
1. If the flame goes out, wait at least five minutes before attempting to relight the fireplace. This allows time to clear the fireplace of gas.
2. Be alert for unusual odors or odd-colored flames, which are often a sign that the fireplace is not operating properly. In such cases, contact your dealer or licensed technician for servicing. Contact the gas company if you smell gas when the unit is off.
Gas furnace maintenance
1. An annual maintenance check of a gas furnace extends the life of the appliance and ferrets out any hidden problems. A qualified heating contractor should vacuum out the unit, inspect the blower motor, inspect the heat exchanger for cracks, check the electronics and perform a multipoint checklist to make sure the furnace is operating properly.
2. Clean or replace the furnace filter frequently during the heating season. This ensures that air returning from the inside of the house is unobstructed and clean when entering the combustion chamber.
3. Keep vents, space heaters and baseboards clear of furniture, rugs and drapes to allow free air movement.
4. Ensure there is free airflow around your furnace and make sure there are no storage items obstructing airflow.
5. Do not store or use combustible materials, such as chemicals, paint, rags, clothing, draperies, paper, cleaning products, gasoline, or flammable vapors and liquids in the vicinity of the furnace.
6. Carbon monoxide is a colorless, odorless and lethal gas that can occur any time there is incomplete combustion or poor venting. Any home that contains fuel-burning appliances, such as a fireplace or furnace, should have a carbon monoxide alarm installed according to the manufacturer’s instructions.
