Feed the fan cable through the hole in the brickwork and leave a short length of cable
'hanging' in the opening made for the fan unit.
Note:
CARE MUST BE TAKEN NOT TO DAMAGE THE TWO PLASTIC CONNECTORS FITTED
TO THE CABLE WHEN PULLING THEM THROUGH THE HOLE. THESE CONNECTORS
ARE FACTORY FITTED AND CANNOT BE RE-ATTACHED ON SITE.
4
Fit the flue spigot to the fan box using the three self-tapping screws provided.
5
Insert the fan box in to the wall as far as it will go and fix it in to place by screwing out
the 3 bolts (1 in the top, 2 in the bottom) into the masonry to clamp the box in position.
Using the 3 bolts, adjust the position of the box so that the fan box duct surrounds
equally on all four sides the duct of the firebox.
Note:
In some cases the 'frog' of the brick may prevent the clamping bolts from being
able to be tightened fully. In this case the clamping plate supplied should be inserted in
the appropriate position and the clamping bolts tightened on to this.
6
Take the glass fibre rope sealing gasket and push it in to the gap between the flue duct
and the fan box spigot. The gasket can be pushed in to the gap using a screwdriver but
care must be taken not to push the gasket in too far. It need only be pushed in to a
point where the edge of the gasket is level with the inner flue duct.
7
Secure the cable gland to its bracket on the fan carrier (See Figure 9) and then connect
the power cable using the 'Molex' snap connectors. Replace the fan carrier and its
gasket into the fan box and secure in place by locating the 'keyhole' slots over the pan
head screws at the rear of the box and using the two lower self tapping screws to secure
the bottom of the carrier in position. Finally tighten the two pan head screws. Any
excess cable should be pushed in to the cavity.
8
It is recommended that a bead of mastic be run around the frame of the wall box to
ensure a water tight seal with the brickwork.
9
Refit the wall box cover.
FITTING THE SEMI-RECESSED FAN SPACER
1
In cases where there is insufficient room to recess the fan unit into the wall the fan
spacer will have to be fitted. This spacer mounts the fan partially out of the wall so that
the spigot does not protrude into the cavity.
2
Place the spacer against the wall, ensuring it is correctly aligned with the flue duct and
mark the position of the four fixing holes on the wall (See Figure 10) Drill and plug the
wall at these positions. Check that the spacer is the correct way up and fix it to the wall.
The spacer is the correct way up when the internal box section with two holes is at the
bottom.
