Appliance and Equipment Safety

The safety of our customers and communities is our highest priority. That’s why at all times, including when severe weather events occur, we strongly advise customers to adhere to the following guidelines associated with natural gas meters and appliances.

Important Information About Furnaces

It's important to check your heating appliances to ensure they're working safely. Clean or replace air filters regularly. Keep the space around the furnace clean and clear, and check to see that the furnace or boiler is free of rust, dust or corrosion. It's also imperative to ensure that furnace panels and grills are in place and that the fan compartment door is closed when the furnace is on - leaving these doors open can cause carbon monoxide to build up.

Signs your heating system needs immediate attention:

  • Gas flames are pale yellow or wavy 
  • Gas appliances are not vented to the outdoors 
  • Rust, corrosion or excessive dust on gas appliances 
  • Excessively dirty, clogged or missing furnace air filters 
  • Gas appliance valves are missing or not properly installed 
  • Blocked, broken, rusted, disconnected, corroded or unsealed appliance vent piping 
  • Soot near burners or appliance venting 
  • Venting not approved by the appliance manufacturer or not venting to the proper place outdoors 
  • Evidence of discoloration at the appliance burner, burner access door or vent area 
  • Gas appliances installed in a garage less than 18 inches above the garage floor 
  • Gas appliances that are missing a fire door

Water Heater Safety

Keep your tap water temperature set at 120 degrees Fahrenheit (the "warm" or "low" setting on your water heater). For children or senior citizens, water temperature between 95 and 100 degrees may be more suitable.

How to test your water temperature:

  1. Run the hot water for five minutes. 
  2. Put a reliable thermometer that registers at least 150 degrees under the water stream. 
  3. If your water is more than 125 degrees, lower the thermostat on your water heater. If you can't find the temperature controls or have any questions, call a qualified contractor or your landlord for help.

Outdoor Grills

July is the peak month for grilling fires, according to the National Fire Protection Association. A stationery natural gas grill can help avoid the safety worries associated with portable grills. Customers are encouraged to take precautions when grilling this summer:

  • Use a certified natural gas contractor to ensure your natural gas line and grill connection are installed properly and according to building codes. To locate a certified contractor, use our online tool.
  • All grills need proper venting and distancing from flammable objects. Position your grill at least 10 feet from flammable objects such as siding, eaves, ceilings, porch rails, overhanging branches or decorative objects.
  • When purchasing a grill, be sure to shop for the right type, since stationary natural gas and portable propane grills have different connection equipment.
  • Keep children and pets at least three feet away from the grill area.
  • Keep your grill clean, removing grease buildup from the grills and the trays below.
  • Make sure your grill lid is open before lighting it.
  • Never leave a hot grill unattended, especially after you’ve finished cooking and you’ve turned up the grill to burn off any remnants.
  • When a grill is not being used, turn off all the burner control knobs including the side burner, then if using a natural gas grill, turn off the shut-off valve on your natural gas supply line.

Other Important Tips

  • Never use a gas range as a space heater. Doing so can cause carbon monoxide to build up.
  • Place space heaters on a level surface and keep them away from curtains and other flammable objects.
  • If you use a natural gas or kerosene space heater, ensure it is properly and safely vented to the outside.


Hurricane season runs from June to November, increasing the likelihood of power outages, especially in southern and eastern coastal states, while tornadoes or other summer severe weather can strike anywhere in the U.S. The safest way to supply backup power to your property during an electrical outage is with a natural gas standby generator. Different from portable generators that run on gasoline, natural gas standby or stationary generators operate automatically and can run indefinitely. To make sure your natural gas generator is ready for storm season:

  • Have your standby generator installed by a qualified contractor to ensure all building codes are followed. To locate a contractor, use our Find A Contractor tool.  

  • Work with your contractor or dealer to size the standby generator correctly to avoid overloads or inadequate power supply. Most dealers have online calculators on their websites. 

  • Read through the owner’s manual to be familiar with your product’s warnings and directions.

  • Stationary standby generators have weatherproof housing to operate safely outdoors, while portable generators can pose risks of electric shock or fire, especially when operated in wet conditions.

  • Make sure your hands are dry before touching a generator. Keep children and pets away from generators. NEVER try to power the house wiring by plugging a portable generator into a wall outlet, a practice known as “backfeeding.”

  • Generators should run only outdoors in an area with plenty of ventilation, away from windows, doors and vents, never inside a home or garage.

Finding the Right Filter

When thinking about home maintenance, your furnace filter is probably the furthest thing from your mind. But it may be time to rethink your home maintenance priorities. Furnace filters are an inexpensive and easy-to-replace item with an important purpose. Filters protect your blower fan and compressor from particles and debris that could damage your system and impact air quality in your home. There are numerous filter sizes, styles and designs to choose from, but with these tips, you’ll be able to quickly and easily pick the best filter for your unit.

Determine the Correct Filter Size

Most furnace filters have their size printed on them, so you can check your existing filter for the correct measurements. If you aren’t able to find the size, check the owner’s manual or website. You can also measure the current filter being used as well as the width, height and depth of the furnace filter slot. Filters normally have two sets of measurements – the “Actual size,” which include the true dimensions of the filter, and the “Nominal size”, which is the actual size rounded up to the next whole number. For example, a filter with an actual size of 19.5” x 19.5” x .75” has a nominal size of 20” x 20” x 1”. Two filters might that have the same nominal size might not necessarily have the same actual size, making it important to check the size of your insert. Take your measurements with you to ensure you’re getting the one that will best fit the available space.

Filter Types and Benefits

Filters have different benefits based on the material that they’re made of and will have a major impact on air quality in your home. Considerations for filter materials might include how long you plan on living in your home or apartment, as well as if you or any of your family members have any medical concerns like allergies or asthma. Here’s a rundown of filter materials and their capabilities.

  • Disposable fiberglass – Prevents larger particles like dust and lint from clogging the system. These are the least expensive option, but can’t remove bacteria, mold, pollen or smaller particles. 
  • Disposable pleated – Removes particles like spores and mites. These are the most common filters as they allow for better air flow while filtering out common allergens and fine dust in the air. If you have asthma or allergies, this is an inexpensive but effective option. 
  • Permanent or disposable electrostatic – Attracts small particles; these filters can be washed to extend lifespan. However, while these filters are good for allergy and asthma sufferers, they are much more expensive to replace than other options. 
  • High-efficiency pleated – Removes the smallest particles. High-efficiency filters are generally designed for major health needs and are often used in commercial buildings like hospitals. However, they can restrict your airflow if your ventilation system isn’t designed to support these types of filters. Check with the manufacturer to make sure that your family stays healthy and comfortable.

Filter Price Points

Filters with a higher minimum efficiency reporting value (MERV) rating will render better air quality, but they cost more to regularly replace. MERV was developed on a scale from 1 to 16 to determine the efficiency of air filters, meaning that the higher the MERV rating, the fewer dust particles and contaminants will pass through the filter. If anyone in your home has special health needs, the investment might be necessary. Consider pets, indoor pollutants and your budget when you’re picking the right filter for you and your family. Regardless of what you choose, make sure to change and clean your filter as recommended to remain as comfortable as possible and help your furnace do its job effectively.
