Prepare Flue Assembly; Installation Of Electrics, Firebox And Fan Box - Baxi GALLERY Series Installer's Manual

INSTALLER GUIDE

7.11 Prepare flue assembly.

1. Measure the total wall thickness
from the outside surface to the
inside face. Add 18mm to this
measurement to obtain the correct
length of flue unit required. This
measurement is for surface mounted
fan box assemblies. Care should be
taken if the fan box is to be
recessed. The fan box is not
intended to be recessed into a
timber framed building.
Figure 16.
2. Measure the flue length from the
inner flue tube at the appliance end
(staggered end) and mark the cut point on the outer pipe of the fan end (Pipes are flush).
3. Insert the polystyrene ring between the inner and outer tubes to support them and cut
both tubes squarely at the marked distance. Remember cut only the fan end, the flush
fitting end.
Important: Remove all packaging from the flue unit. Remove all polystyrene from the
flue unit after cutting.
4. Now the flue tube is ready for installation.
8. INSTALLATION OF ELECTRICS, FIREBOX AND FAN
BOX
Important : Under no circumstances should the electrical loom be fed between the
inner and outer sections of the flue tube.
Ensure the mains electrical supply to the appliance is in place and is isolated.
Important : We strongly recommend that a dust mask and protective gloves are worn
in order to minimise exposure to Rockwool fibre whilst fitting the insulation jacket .
Ensure the Rockwool insulation jacket is securely positioned on the back of the firebox.
Fit the top part of the jacket to the top of the firebox by securing with two tags as
shown in figure 21.
Note : Use aluminium tape provided to seal adjoining edges of the jacket as shown,
unless cable fixing method is to be used, in which case, tape up after cables are in
position.
