8. Actuator Cabling
The following shows one example of a method to open and close the Chimney Vent Baffle and Door. The
Linear actuator is connected to a rod running the length of the structure. The rod is connected to a spring
which is in turn fastened to the end wall. When the linear actuator operates, the rod is pulled to the left in
the example below hence opening the baffles. When the actuator reverses, the spring force closes the
baffles.
The door cable can be fastened to a cable tie on the wall beneath each Chimney Vent.
