Turn off the hood and check to see if the damper closes.

A qualified HVAC contractor should also ensure the proper operation and venting of all combustion equipment in the home.

Wire the system as shown.

FALSE TRIPPING

Under certain extreme conditions there could be false tripping of the damper (opening when the range hood blower is off). If false tripping

is encountered, place an in-line backdraft damper (available from your local hardware store or from Zephyr) between the probe and the

roof or wall cap.
