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
185 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.

1. The boxes required when the boiler is installed with a horizontal flue are as follows:-
Box 1.............................. Cased boiler fitted with water and gas valves, union bends and washers
Mounting bracket plus screws and wall plugs
Condensate discharge pipe
Literature pack and Wall template
Box 2 .................................CD Easy-Flue 500 mm or CD Easy-Flue 1000 mm. Both include 90° bend and horizontal flue terminal
Note: NOT
required for vertical flue
Notes:
a. All flues must be suitable for InTec condensing boilers.
b. CD 750 mm and 1000 mm flue extensions are available, if required.
2. Unpack boiler and remove the loose items, packs and mounting bracket.

The boiler can be stood in an upright position, (to allow this, the union bends should be
removed so that they do not protrude beneath the bottom - check this before standing the boiler
upright). It is recommended that two persons lift the boiler
