Assembly of the Fan Box to the Exterior Wall
With the flue attached to the rear of the fire and located in the correct position the flue and the wiring harness
will be protruding from the wall. Providing the fire will not have to be removed for any further structural work
to be carried out the fan box can be fixed into position and the electrical connection made.
Feed the wiring harness through the 21mm hole in the fan box mounting plate and slide over the flue tube.
Hold in position against the wall and place a straight edge across the outer flanges. Scribe a line to mark the
maximum protrusion of the duct See Fig. 17. Remove the plate and trim the flue duct down to the correct
length with tinsnips or hacksaw, taking care to prevent distortion of the flue duct. Replace the plate, spot drill
through the four fixing holes and using the plugs and screws supplied, fix into position.
IMPORTANT: THE FAN BOX MOUNTING PLATE MUST BE HORIZONTAL TO ENSURE CORRECT
OPERATION OF THE FLOW SENSE SWITCH

In most installations
the flue tube will need
to be trimmed to the
correct length.
To establish the
maximum length
required, the fan box
mounting plate will have
to be removed from the
fan box assembly by
unscrewing the six fixing
screws around the fan
box cover. The three self
tap screws securing the
deflector plate in
position, giving access to
the four fixing screws in
the fan box mounting
plate see Figs. 16 & 17.
