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.
3. Mark the position of the fixing holes for the wall
plate (Fig. 20).
4. Mark the centre of the flue hole (rear exit).
Flue Hole ø
For side exit: project the horizontal side flue centre line
127mm core drill
into the corner of the room and along the wall to
150mm core drill
where the flue hole will be drilled. (Fig. 20).
The diagram (Fig. 21) shows the dimensions required to
175mm core drill
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.

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).
