When burning fossil fuel (wood, propane, oil, natural gas), carbon monoxide (CO) can be produced by lack of air, improperly working appliances or poor flue conditions. Follow these maintenance and inspection tips:
- Don't use temporary heating systems. Never use a gas or propane range to heat your home.
- Make sure your permanent heating system and appliances are operating and vented properly. Have the heating system and appliances inspected every year by a licensed heating contractor.
- Keep flues and chimneys clean and free of debris.
- Check for rusted or pitted flue pipes from your furnace and water heater. Don't patch or repair these pipes; have them replaced immediately.
- Check the flames. All gas flames should be crisp and blue. If flames are white or yellow, appear "soft" or wavy, or if you see soot or carbon deposits, shut off the furnace and call your heating contractor.
- Hold your hand under the vent pipe on the furnace. If you notice hot air backing out of the vent, turn off the furnace and call your heating contractor. Hot air can mean blockage in the vent or chimney.
- Use a clean filter -- your furnace will run smoother and more efficiently. Standard air filters need to be changed once a month. Newer filters may be washable or require less frequent changing. Check the owner's manual.
- Be sure a fire is completely out before closing the fireplace damper.
- Do not operate a barbecue grill in a closed area.
- Don't start or run gasoline-powered equipment in a closed area.
