SIDE FLUE - PREPARE THE WALL
Refer to Figs. 15 and 16.
1.
Decide upon the position of the boiler, ensuring that the
position of the flue terminal will meet the requirements
given in section 2.6.
Using the wall mounting plate as a template and adding
the following dimensions to the raised edges of the
mounting plate will give the space necessary for the
boiler including the minimum clearances required for
servicing:-
Top 107 mm, Bottom 528 mm, Each side 78 mm.
The side of the white case is 68 mm from the raised edge
of the mounting plate.
Note that the maximum distance from the side of the
white case to the OUTSIDE wall surface is 2970 mm.
2.
Again using the mounting plate as a template mark the
positions of the five mounting plate fixing holes, the side
of the boiler and the horizontal centre line of the flue as
shown in Figs. 15 and 16.
Ensure the plate is level and the right way up.
3.
Continue the horizontal flue centre line across the wall
until it reaches the side wall and continue it around onto
the side wall as shown in Fig. 16. Ensure these lines are
level.
4.
Mark the position of the hole for the flue duct as shown in
Fig. 16.
5.
Cut the 115 mm dia. hole in the wall and drill and plug the
fixing holes to accept 2½" lg. No.12 woodscrews.
6.
Make a note of the finished wall thickness, this is very
important and is required in section 3.8 when cutting the
flue/terminal assembly to length.
7.
Secure the mounting plate in position with five 2½" lg.
No.12 woodscrews (not supplied). Ensure it is level and
the right way up.

3.8
SIDE FLUE - CUT THE FLUE /TERMINAL ASSEMBLY TO LENGTH
Refer to Fig. 17.
The finished wall thickness plus (+) the distance from the
inside wall to the side of the white case plus (+) 30 mm will
give the length of the flue/terminal assembly required.
If the length required is less than 500 mm proceed as follows,
if it is more go straight to section 3.9.
1.
Mark the flue/terminal assembly to the required length,
measure from the back of the terminal flange.
2.
With the cutting jig, supplied with the flue/terminal
assembly, in position over the flue/terminal assembly as
shown in Fig. 17, cut the tubes to the correct length.
Using the cutting jig should ensure that the tubes are cut
square.
3.
Clean up the edges of the cut tubes and discard the
cutting jig.
