Boiler Installation - gledhill GB10 Installation And Servicing Instructions

4.1. INSTALLATION PREPARATION
Unpacking Of Boiler
Important: With regards to the Manual Handling Operations, 1992 Regulations, the following lift operation
exceeds the recommended weight for one man lift.
Stand the boiler carton upright.
Cut and remove the securing straps and lift off the carton sleeve. Place aside any loose components until
required.
Carefully lay the boiler on its back, remove the two front casing panel-securing screws and lift off the panel
from the two retaining lugs.
Remove the two inner casing panel-securing screws at the bottom of the front panel, and then lift off the two
retaining lugs.
4.1.1. Wall Template
A wall template is supplied with the boiler. This should be used to mark the boiler fixings and flue outlets and
for checking the minimum clearances required.
4.1.2. Flue Hole Cutting
The standard horizontal flue is designed with an internal fall of 35mm/metre towards the boiler for disposal
of condensate. If the standard flue length alone is being used then the flue hole of diameter 105mm can be
cut in the position marked on the wall template.
For standard side flues the horizontal flue centre line on the wall template should be extended to the side
wall, and the vertical centre of the flue hole marked at 176mm from the back wall.
For installations with external access, a 105mm diameter core drill can be used.
For installations with internal access only a 125mm diameter core drill should be used.
When using extension pipes with the horizontal rear flue, a core drill size of 125mm should be used to allow
the extension pieces to slope at 35mm/metre (2.5°) towards the boiler.
For extended side flues , the flue hole centre should be determined by extending the dashed inclined line on
the template to the side wall. This dashed line is drawn at 35mm/metre (2.5°) rise from the boiler. Where
this line reaches the side wall, a horizontal line should be marked. The vertical centre line of the flue should
then be marked at 176mm from the back wall, see diagram 5.3.
To allow for the flue passing through the wall at this angle a 125mm hole should be drilled irrespective of
internal or external installation.
If necessary remove the wall template whilst drilling the flue hole.
4.2. Hanging Bracket Fixing
If previously removed, reposition the wall template over the flue hole and mark the position of the fixing holes
for the hanging bracket.
Mark and drill the fixing holes and secure the hanging bracket.
