Then, when it becomes cold again, the floor furnace automatically comes back on igniting the throw rug. Be sure to remove rugs whenever the unit is switched on. Central Heaters Clean or replace the furnace filter. Clean the entire furnace area using a vacuum cleaner to remove dust and lint. Be sure to remove any brooms, boxes, magazines, newspapers, or any other combustible material stored in the heater closet.
Fireplaces Inspect the fireplace and chimney at least once a year.
Look for cracks in the firebox, flue, and chimney. Also check for build up of soot and creosote inside the flue. Open the damper enough to allow the smoke and gases to escape up the chimney. Never start a fire with gasoline, kerosene, or any other flammable liquid. Always keep a good-quality metal fireplace screen in front of the fireplace whenever it is being used to prevent burning logs from rolling out or embers from flying out.
