3.2 Installing the Boiler
Please check that you are familiar with the installation
requirement before commencing work.
The installation accessories described in the following list are
included in the boiler packaging:
- Hanging bracket
- A paper template (showing the dimensions of the boiler with
5 mm side clearances)
- Connection valves (compression)
- Screws and washers
- Installation, Servicing and User manual
3.2.1 Method of positioning the boiler on the wall
The paper template can be used to ensure the correct
positioning of kitchen cabinets etc.
The paper template has to be fi xed to the wall and used to
locate the position of the hanging bracket and the centre for
the fl ue hole.
Drill and plug the wall and secure the hanging bracket using
the screws provided ensure the hanging bracket is level.
Remove the boiler from its packaging and remove the front
casing panel.
Place the boiler on the hanging bracket.

3.2.2 Connecting the boiler to the system
- Remove the boiler casing as described on page 17
- Remove the caps and connect the valves to the boiler using
the washers provided
- 5 x fi bre washers for the CH fl ow and return, cold water inlet,
gas inlet and hot water outlet connections.
3.2.3 Safety Valve Discharge and Condense Outlet
The pressure relief valve pipe is made of copper. It should
terminate below the boiler safely outside the premises. Care
should be taken that it does not terminate over an entrance or
window or where a discharge of heated water could endanger
occupants or passers by.
Warning !
Do not apply heat to the copper safety valve outlet pipe
whilst it is connected to the 3 bar safety relief valve.
Fill the central heating and DHW system and bleed air from
the system as described in the Commissioning instructions
(page 28).
The system should be carefully checked for leaks, as
frequent refi lling could cause premature system corrosion
or unnecessary scaling of the heat exchanger. The pipe from
the trap should be connected to a drain as described in the
relevant regulations.
Note: A fi lling loop is not supplied with the appliance.
A fi lling loop must therefore be supplied and fi tted in a
convenient position for the end user to access.
Note: Connections viewed from behind boiler
.
Pay special attention not to bend the condensate silicone
drain pipe is such a way as to interrupt the fl ow. Please only
use drain pipe material compatible with condensate products
(refer to BS 6798).
The condensate fl ow can reach 2 litres/hour because of the
acidity of the condensate products (Ph close to 2), take care
before operation.
See page 13 for condensate discharge options.
