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 135 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.
