Installing Enervex Fan on Masonry (Brick Chimney)
Step 1: Prepare Fan Location
The installation procedure is the same whether the flue is round or square. If a clay tile flue liner is installed, it might stick up a few inches. Cut it back so it is flush with the chimney crown.
Measure the inside diameter of the flue, cut a corresponding hole in the fiber mat leaving a minimum distance of 3/4” to any side of the fiber mat.
The aluminum foil on the fiber mat must face upwards (against fan base).
Step 2: Preparation of Fan
Locate the installation brackets in the grooves on the underside of the fan base using the bolts and nuts supplied to secure the brackets. Note that the bolts shall be installed from the bottom side in the two inner holes.
Adjust the final position of the brackets ensuring that there is clearance between the brackets and the flue wall. If the brackets touch the wall, it may generate some vibration noise.
Step 3: Attaching the Fan
The chimney fan is now ready for installation on the top of the chimney. Place fiber mat with the aluminum foil facing upwards on the top of the chimney, and place the fan on top of the mat.
Caution: Under conditions with extremely strong winds surrounding the top of the chimney, the chimney fan must be secured by steel wires or similar.
