INSTALLATION

5.1 UNPACKING
1. The boiler carton also contains the following:-
Connection kit (union bends, washers and gas service cock)
Mounting bracket plus screws and wall plugs
Condensate discharge pipe
Literature pack and Wall template
A suitable Alpha flue system must be selected to use with the boiler.
Notes: a. All flues must be suitable for Alpha condensing boilers.
b. CD 750 mm and 1000 mm flue extensions are available, if required.
Damaged products must not be used.
2. Unpack boiler and remove the loose items, packs and mounting bracket.
Note: The boiler can be stood in an upright position (only while the valves and union bends are not
fitted).
It is recommended that two persons lift the boiler.

Minimum clearances
5.3 PREPARE THE WALL - Fig. 5.2
1. Decide upon the position of the boiler taking into account the clearances required
for servicing and the flue terminal position.
2. Tape the template to the wall (ensure it is level and the right way
up) and mark the position of the holes for the boiler mounting
bracket. If rear exit flue is used, mark the position of the hole for
the flue.
3. Side exit flue - Continue the horizontal centre line of the flue
across the wall to the side wall, then along the side wall 138 mm
(ensure the lines are horizontal). This will give the position of the
centre of the hole for the flue.
4. Cut the 110 mm diameter hole (or use a 107 mm core drill) in
the wall for the flue.
Notes: 1. Ensure the hole is horizontal.
2. For internal fitting of the flue, using the flue sealing
collar supplied, cut a 130 mm dia. flue hole using a 127
mm core drill.
5. Drill the fixing holes (10 mm dia.) to accept the No.10 plugs
supplied. Using the screws supplied, fit the mounting bracket.
