Steps:

  1. Ideally, a carbon monoxide detector should be installed on every level of the home. It’s especially important to place one near combustion appliances like a furnace, water heater, gas stove, or gas fireplace.
  2. Ensure batteries are changed twice per year, even on models that are hardwired or plugged in to an outlet.
  3. Replace the entire carbon monoxide detector every five years.
