Safety & Installation Tips

• Placement is Key: Propane is heavier than air and sinks, while CO is roughly the same weight as air. For a combo unit, mount it near the floor (about 4–10 inches up) to ensure the propane sensor catches a leak early.

• Replacement Date: These sensors have a 5-year lifespan. Check the "Date of Manufacture" on the back; the unit will chirp at the 5-year mark to let you know it’s time to replace it.

• Vacuum Regularly: Dust and pet hair can clog the sensor. Lightly vacuum the front grill once a month to keep it sensitive.

Installation Tip: Propane is heavier than air and sinks, while CO is roughly the same weight as air. For the best dual-gas protection, mount this unit 4 to 10 inches above the floor to ensure the propane sensor catches a leak at the earliest possible moment.
