Installation on Steel Chimneys

Installation of the Chimney Fan

The installation of the chimney fan is estimated to take an average of 15 minutes, when installed on a brick chimney or a steel chimney. The installation time does not include: setting up ladder, lifting fan to the top of the chimney, cutting back flue tile etc. Only the installation of fiber mat, mounting brackets, steel chimney adaptor, safety wire, and junction box is included. Open the carton and remove all packing materials. The standard chimney fan package includes: chimney fan w. bird screen, 3-4 ft cable in conduit, weatherproof junction box (not shown), fiber mat, safety wire with anchor, Installation brackets (set of 4), motor speed control (not shown), Installation Instructions and a Warranty Registration Card.

Make sure the axial vane turns without making noise or offering resistance. Also make sure it is in balance.

Installation on a steel chimney follows the same procedure as for masonry chimneys, except that a steel chimney adaptor FRS is required. The adaptor (optional) fits standard flue dimensions or as required. The collar slides into the flue where the long engagement ensures safe anchoring.

EXHAUSTO Steel Chimney Adapter is used when installing the chimney fan on the top of a single, double or triple wall steel chimney.
The adapter is designed to slide into the steel chimney for a tight fit. The outer diameter of the collar is 1/8" smaller than the inner diameter of the steel chimney and has a 5" deep collar.

Step1:

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).

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 installation brackets ensuring that there is clearance between the brackets and the flue wall. If the brackets touch the flue wall, it is likely to create some noise from the vibration.

Step 3:

The chimney fan is now ready for installation on the top of the chimney. Place the fiber mat on the top of the chimney, with the aluminum facing upwards, and place the fan on the top of the mat.

Step 4:

Decide on the location of the bolt and wall plug (1). Drill a hole in the stack and secure the safety wire by the bolt and the wall plug. Take the safety wire through the hole in the fan base and return it to the free clamp of the wire. Tighten the safety wire slightly (2) and crimp the free clamp to provide secure anchoring for subsequent safe cleaning and service. Fit the liquid tight junction box (3) on the outside wall of the chimney stack, but make sure the conduit is 10-12" away from the fan outlet. Run the installation cable to the fan speed control/switch and the main electric supply.
