Electrical installation
Install a power supply at a switched fuse having a minimum separation of
3mm at all poles. The spur should be readily accessible to the user, easily
identifiable and preferably sited adjacent to the appliance. It should only
connect this appliance.
WARNING : Ensure the supply is isolated before proceeding.
Withdraw the electrical control unit and its heatshield by removing the two
fixing screws. See figure 24.
Ensuring continued isolation of mains supply, withdraw end of mains
cable through the large rectangular aperture in the firebox.
Note : Under
no circumstances should the mains cable provided be removed from the
appliance.
Connect the end of the mains lead to the fused spur. If it is necessary for
the mains lead to be routed behind the appliance, then it can be fastened
to the lower part of the outer heatshield using two ‘p’ clips. If this is the
case, remember to leave 200mm of slack as with
the control loom (see page 14).
With the electrical supply and fan box loom now
connected, the enclosure can be replaced as
shown in figure 24.
Locate the cable loom earth tags and secure to the
fan box earth stud using the M4 nut and
shakeproof washer supplied. Connect the cable
loom to the pressure switch - see figure 26.
Replace the fan unit taking care not to snag or
otherwise damage the electrical fitments. Connect
the cable loom to the fan unit. (See figure 52 in
section entitled “To remove the pressure
switch”).
Upon completion of cable installation ensure that the loom and
cables do not touch the horizontal surface of the fan casing
immediately above the rectangular flue gas outlet. If cables run close
or are in contact with this surface they should be held clear using
the additional cable ties provided.
Upon completion ensure a neat and tidy installation before
replacing the fan box cover .
Replace the fan box cover and weather shield (figure 28) and secure
using the two screws provided.
Refit the burner unit
Replacing the burner unit, is the reverse of removal. See text,
“preparing for installation”.
In addition the burner loom is to be secured to the burner support bracket using the
fixing clip supplied. (See figure 27).
