Appliance Safety

Gas appliance maintenance is always the customer’s responsibility, but we're here to explain how you can keep your appliances operating safely and efficiently.

We are excited that you have chosen to use appliances that run on natural gas—a clean, abundant, and efficient natural resource. Properly caring for appliances helps to keep them operating smoothly. The following are some important tips:

  • Have your gas appliances inspected regularly by a qualified professional at least every year, or as often as the manufacturer recommends. Not performing regular maintenance may result in inefficient appliance operation, and in some cases, dangerous exposure to carbon monoxide.
  • Never store rags, mops, paper, or other combustibles near any gas appliance.
  • Never store anything near a gas appliance that might interfere with normal appliance airflow. Make sure that your gas fired appliances have plenty of air so they can work properly.
  • Never store or use flammable products in the same room or near any gas or heat-producing appliances. Such flammable products include gasoline, spray paints, solvents, insecticide, adhesives, insect foggers, varnish, cleaning products, and other pressurized containers.
  • Monitor your water heater temperature. Please re-check your hot water setting after the heater has been serviced and after the pilot has been relit.
  • Check outdoor appliance exhausts year round. If the vent becomes blocked, an emergency switch should stop the furnace from running. Snow or ice can build up and block the opening, and even bird nests and "stink bugs" have been cited as the cause for some furnace vent problems. Never cover openings with mesh or netting, as this may affect proper operation.

Appliance Safety Tips


Maintaining your furnace for safety and efficiency is important. Follow these simple tips to make sure your furnace is operating correctly:

  • Replace your furnace filters at least three times during each heating season.
  • In order to help the air flow properly, keep heat registers and cold air returns clean and clear of furniture and draperies.

Another way to make sure your furnace is performing at its best is to always schedule to have it, and all of your other natural gas appliances, inspected by a qualified professional. These inspections can help you make sure your home is properly heated for the colder months, and help you avoid any other potential problems. Your qualified professional should:

  • Test the thermostat
  • Visually inspect the heat exchanger, motor, and vents
  • Lubricate the blower motor
  • Check the flue
  • Check the pilot light, unless your furnace features pilotless ignition

Floor Furnace

  • Avoid lint build-up by vacuuming the floor furnace and the area around it regularly.
  • Keep children away from the grill, as it gets very hot.
  • Avoid fires—don't place rugs, furniture, or combustible items over or near the grill, and do not block the airflow.

Wall Furnace

  • Clean inside the burner compartment of a built-in, vented wall furnace once a month during the heating season to prevent lint build-up, or in accordance with the manufacturer’s instructions.
  • Never place combustible items on or near the appliance or vent.

Central Gravity Furnace and Central Forced-Air Heating

  • Keep furnace heat registers free of obstructions.
  • Don't store items nearby that might stop or restrict airflow.
  • Many gas furnaces use air from the indoors to operate. Lint, dust, and pet hair carried by air, or items stored in or around the furnace can block or restrict airflow. In order to operate safely and efficiently, your gas furnace must be kept free of dust and lint build-up and other obstructions stored near the furnace. Never store or use flammable products, such as newspapers, flammable liquids or cleaning products near the furnace.
  • Most forced-air furnaces have a filter that cleans the air before heating and circulating it throughout the home. Inspect your filter monthly for lint build-up during periods of furnace use. Clean or replace the filter if necessary. Replacing filters often can improve appliance efficiency and reduce your energy consumption.
  • When installing a new or cleaned filter, be sure to re-install the front panel door of the furnace properly so it fits snugly. Never operate the furnace without the front-panel door properly in place because doing so may create the risk of carbon monoxide poisoning.
  • Most new forced-air furnaces have a safety (interlock) switch that prevents furnace operation when the filter compartment door/panel is not in place. However, some older forced-air furnaces do not have a safety switch and can be operated with the filter compartment door or panel off or not properly in place.

Water Heater

All gas appliances have a main burner flame and many also have a pilot flame. Follow these tips to reduce the risk of flammable vapors being ignited by these flames:

  • Water heaters installed in garages must be elevated so the pilot light or other source of ignition is a minimum of 18 inches above the floor, or installed per local building codes and the manufacturers’ installation instructions.*
    *Note: Manufacturers’ labels and/or instruction manuals for new Flammable Vapor Ignition Resistant (FVIR) tank water heaters may or may not indicate the 18-inch elevation requirement for garage installations. Always follow the manufacturer’s recommendations.
  • Never store or use flammable products such as gasoline, paint thinner, cleaning products, etc. near or in the same room as any gas or heat-producing appliance.
  • Lowering your temperature setting can prevent scalding accidents and lower your energy costs. Water temperatures above 125° F can cause severe burns or even death. Households with small children, or disabled or elderly persons may require a lower thermostat setting to prevent contact with "HOT" water. Please refer to your water heater manufacturer's recommendations for safe water heater temperature settings.


Follow these safety precautions to reduce the risk of fire or injury:

  • All gas dryers are required to be vented to the outdoors.
  • Do not exhaust gas dryers into an attic, chimney, wall, ceiling, or concealed space of a building.
  • Use only approved metal vent ducting material. Plastic, vinyl and foil accordion style materials are not approved for gas dryers.
  • Inspect the exhaust duct regularly to ensure that it has not become crushed, kinked or otherwise restricted.
  • Keep area around the exhaust opening and adjacent surrounding areas free from accumulation of lint.
  • Periodically clear the interior of the exhaust duct. This work should be performed by a licensed, qualified professional.

Range and Oven

  • Keep range top area clean of grease. Grease is flammable and excessive build-up may result in a fire.
  • Do not use the range top or stove to heat the home.
  • Do not install items such as aluminum foil in the oven or range top to avoid restricting exhaust vents which may result in carbon monoxide poisoning.

Natural Gas Fireplace Logs (ventless and vented)

  • To help avoid serious accidents, the damper must be kept open on a permanent basis. Use the damper lock included with the gas log assembly kit. Vented gas logs can only be installed in an existing masonry fireplace.
  • You may not be required to install ventless gas logs in an existing masonry fireplace. Always follow the manufacturer's installation instructions and be sure the logs are placed exactly as recommended. Not following the manufacturer’s instructions may result in carbon monoxide.
  • Always ensure gas appliances are installed in an area with sufficient air for combustion as outlined in the International Fuel Gas Code or per local code requirements.
