FURNACE HEATING It’s important that you have your furnace inspected to ensure that it is in good working condition. Be sure all furnace controls and emergency shutoffs are in proper working condition. Leave furnace repairs to qualified specialists. Do not attempt repairs yourself unless you are qualified. Inspect the walls and ceiling near the furnace and along the chimney line. If the wall is hot or discolored, additional pipe insulation or clearance may be required. Check the flue pipe and pipe seams. Are they well supported, free of holes, and cracks? Soot along or around seams may be an indicator of a leak. Is the chimney solid, with cracks or loose bricks? All unused flue openings should be sealed with solid masonry. Keep trash and other combustibles away from the heating system.
