Appliances can pose safety risks when they malfunction or are used improperly. Follow these tips to keep your appliances running well.

Space Heaters

Gas space heaters are a safe way to produce heat if they are used properly, installed by a qualified professional, and maintained well. Be sure to do the following:

  • Have your gas heater and venting system professionally installed and inspected according to local codes.
  • Do not reinstall used space heaters.
  • Keep gasoline and other flammable liquids and combustible materials away from appliances and other sources of ignition.

Water Heaters

  • Make sure your water heater is set to a safe temperature.
  • Check the water temperature before placing a child in the bathtub; never leave a child alone or with other young children in the bathtub.
  • Be sure to have your water heater inspected by a plumbing or heating/cooling contractor.

Appliance Connectors

Connectors should be inspected periodically by a qualified professional and replaced as needed. Keep the following in mind:

  • Hard pipe connectors should be used on all stationary appliances (house heating boilers/furnaces and water heaters).
  • Flexible gas pipe connectors should be used only on moveable appliances (ranges and dryers).
  • No more than one flexible connector should be used per appliance. Multiple flexible connectors should never be piped together.
  • No connector should exceed six feet (1829 mm) in length. Connectors should also never be concealed within, or extended through, walls, floors, partitions, ceilings, or appliance housings.
  • Be sure to have a licensed professional install an AGA/CSA approved flex pipe connection (this approval should be indicated on the ring of the connector) to the manufacturer’s standards and per the demand for the appliance.
  • Uncoated brass connectors are dangerous and unacceptable. If your appliance is more than 20 years old, there is a good chance that it has an uncoated brass connector. The only safe way to tell is to have a qualified contractor check it and replace any uncoated brass connectors.
  • After disconnecting gas appliances, gas connectors should always be removed and the fuel line must be plugged and capped.
