Single fan on brick chimney
Step 1: Prepare fan location
y
The installation procedure is the same whether the ue is round
or square. If a clay tile ue liner is installed, it might stick up a few
inches. Cut it back so it is ush with or no more than 10 mm above
the chimney crown.
y
Measure the inside diameter of the ue, cut a corresponding hole
in the mineral wool mat leaving a minimum distance of 20 mm to
any side of the mineral wool mat.
Step 2: Preparation of fan
y
Locate the installation brackets in the slots going through the fan
base part, using the bolts and nuts supplied to secure the brackets.
If the ue diameter is larger than the chimney fan inlet, the bracket
can be installed underneath the base part. Note that the bolts
must be installed from the bottom side.
y
Adjust the nal position of the brackets ensuring that there is clea-
rance between the brackets and the ue wall. Approximately 5-10
mm. Ensure the brackets do not touch the ue wall, otherwise
direct contact may generate vibration noise.
Step 3: Attaching the fan
y
The chimney fan is now ready for installation on the top of the
chimney. Place mineral wool mat on the top of the chimney, and
place the fan on top of the mat.
y
Mount the safety wire in the chimney. Use the supplied screw
and rawlplug for securing it to the chimney . Then mount the wire
through the hole in the base plate and into the wire lock.
y
Tighten the safety wire slightly and tighten the wire lock , so that
the chimney fan is secured when opened for service and cleaning
purposes
