4.1 Unpack & Prepare the Wall & Boiler
These instructions assume you have chosen a
suitable boiler location which will also allow
correct installation of the condensate and flue
systems.
1. Carefully unpack the boiler, leave the
packing around the base of the boiler
fitted. Do not discard other packaging until
all the items are accounted for and/or the
boiler is installed.
2. Place the mounting template in the proposed
boiler position ensuring that it is level.
Minimum clearances, fixing points,
pipework centrelines and flue incline are
all accounted for on the template.
3. Mark the flue hole, mounting bracket fixing
positions (two), boiler securing point and
pipework centre lines then remove the
template.
4. Drill (7 mm drill) and plug the three mounting
holes.
Drill (on an incline, approx. at least 1.5° to
ensure the condensate drains back to the
boiler) a 105mm diameter hole for the flue
through the wall or a 127mm diameter hole if
the Internal Fitment Kit is being used.
5. Secure the mounting bracket to the wall
using two No. 12 x 2" woodscrews
(supplied).
6. Lift the boiler by the packing at the base
onto the mounting bracket.
7. Remove the packing from the base and
square boiler to the wall using the alignment
screws on the back panel. Pull the door panel
down and remove the two securing screws.
Slide off the controls cover assembly and put
safely aside.
8. Ensure the boiler is secured to the wall
(using the third No. 12 x 2" woodscrew)
through the hole in the bracket at the rear of
the boiler case.
Note: The anti-theft securing kit (Part No.
238035POT) may be used in place of the
third woodscrew if required.
