Question: Do these dampers need to be installed vertically or in a horizontal run? I am using this to control a heating duct from an outside wood burning furnace that is ducted into a forced air furnace system
Answer: The Fantech 10 inch spring loaded backdraft damper can be mounted in a vertical or horizontal duct run.
Question: I have an exhaust in which the pipe curves downward and this the exhaust air exits downward. Can I install this damper upside down in this configuration so that when the fan turns on the dampers open downward and when the fan is off the dampers return to their closed position?
