Gas Heating Equipment

If your natural gas heating system has air filters, clean or replace them regularly before they become clogged with dirt. Install new filters per the manufacturer's instructions. Keep the area around your furnace clean and free from litter and combustible materials. Never store flammable liquids in your home or near fuel-burning appliances. The vapors can be ignited by pilot lights and appliance flames.

Check your heat exchanger.

A gas heater or furnace has a heat exchanger that forms an envelope separating the combustion area from the heated air. A crack in the exchanger can allow toxic carbon monoxide to mix with air sent out into the room. Inspect the exchanger regularly.

Check flues and vents regularly.

Every year or two, have a service representative inspect your furnace, vents, connections, and chimneys for corrosion and blockages. In newer high-efficiency gas furnaces, the flues are subject to corrosion. They tend to deteriorate faster than older models and can plug up completely, so have them checked more often. If you have a high-efficiency furnace that exhausts outside your home, keep intakes and vents clear of debris, snow, and ice.

Keep your furnace filters clean and your heating equipment and flues in good working order.
