10.0 Installation
Check Site Requirements ( section 7 ) before commencing.
10.1 Initial Preparation
The gas supply, gas type and pressure must be checked for suitability before connection (see Section 7.4 ).
1. Cut the banding and remove the fixing template, wall plate and literature pack ( Fig. 19a ) from the carton.
2. After considering the site requirements (see Section 7.0 ) position the template on the wall ensuring it is level both horizontally and vertically.
NOTE: When fitting Plume Displacement Kit refer to the instructions supplied for details of installation of the flue.
3. Mark the position of the fixing holes for the wall plate ( Fig. 20 ).
4. Mark the centre of the flue hole (rear exit). For side exit: project the horizontal side flue centre line into the corner of the room and along the wall to
where the flue hole will be drilled. ( Fig. 20 ). The diagram ( Fig. 21 ) shows the dimensions required to ensure any horizontal flue is installed with the
correct fall to the boiler. Mark the offset (V) dimension and if required, mark the position of the gas and water pipes.
Remove the template.
5. Cut the hole for the flue (minimum diameter 127mm, see table ( Fig. 20 ) for wall thicknesses and flue diameters).
6. Drill and plug the wall as previously marked. Secure the wall plate ( Fig. 22 ).
7. Ensuring the wall plate is level both horizontally and vertically, drill and plug at least 5 securing positions at the top and bottom through the wall plate.
Utilising the slots available ensure the wall plate is square and secure to the wall ( Fig. 22 ).
8. Additionally drill 2 relief holes 10mm deep in the wall as shown on template ( Fig. 22 ).
9. Loosely route the condensate discharge pipe to the lower left hand side of the wall plate.
