Why Can't I Use the Auto-Out Ventood Canisters Under a Microwave?

The typical clearance of an over-the-range microwave or cabinetry to the stovetop is much lower than that of a venthood, as pictured below. Auto-Out Microwave was specifically designed to address this issue. The closer the fire suppressor is to the cooktop, the smaller the spread of the fire-suppressing powder when it is disbursed from the device. Because the clearance of an over-the-range microwave is shorter, we designed Auto-Out Microwave to position a fire suppressor directly over the specific burner at the time of the fire event

HOW DOES IT WORK FOR FIRES ON THE BACK BURNER?

 

  • Auto-Out® Microwave (M) is sold in a set of two - one for each side of the cooktop.

  • After Auto-Out® M is installed, the fire suppressor is positioned above the back burners.

  • When a fire occurs on the back burner, flames actuate the triggering mechanism, causing

  • Auto-Out M to discharge the fire-suppressant powder onto the fire.

​

HOW DOES IT WORK FOR FIRES ON THE FRONT BURNER?

  • If a fire occurs on the front burner, flames touch the front of the Auto-Out M where a fire-sensing activator is located.

  • This causes the Auto-Out M to automatically rotate, which puts the fire suppressor over the front burner.

  • The flame then triggers the fire suppressor (now positioned in front) to release the powder onto the front burner.

​

Also, the typical depth of the microwave is typically around 14” from the back wall, whereas the depth of a venthood is much greater. If you were to use the Auto-Out Venthood canisters under a typical microwave or cabinets, it is unlikely that the fire-suppressing powder would reach the front burners.
