6 Installation
6.1
General
Installation must be carried out in accordance with the prevailing
regulations, codes of practice and the recommendations in this manual.
Danger
If the boiler is installed in a compartment do not use it for storage
purposes. Do not obstruct any purpose provided ventilation
openings.
Caution
Where the boiler is sited in an unheated enclosure provision must
be made to protect against frost, e.g. frost thermostat, pipe
thermostat.
Important
If the boiler stand-off kit has been used the copper tails are
reversible and can be used here.
Ensure the sealing caps are removed from the boiler connections under
the boiler (including the condensate trap).
Important
A small amount of water may drain from the boiler once the caps
are removed.
Remove the taps, elbow and sealing washers from the fitting kit.
Connect the appropriate tap to the heating flow and return pipework, gas
supply and mains cold inlet. The elbow must be connected to the DHW
flow pipe.
Using the sealing washers provided connect the taps and elbow to the
boiler.
Ensure all joints are tight.
6.2
Assembly
6.2.1
Fitting the pressure relief discharge pipe
1. Remove the discharge pipe from the kit.
2. Determine the routing of the discharge pipe in the vicinity of the boiler.
Make up as much of the pipework as is practical, including the
discharge pipe supplied.
Important
Make all soldered joints before connecting to the pressure relief
valve. Do not adjust the position of the valve. The discharge pipe
must be installed before pressurising the system.
3. The pipework must be at least 15mm diameter and run continuously
downwards to a discharge point outside the building.
4. Firmly engage the flange on the pipe into the pressure relief valve
outlet grommet, ensuring it is pushed fully in.
5. Complete the discharge pipework and route it to the outside discharge
point.
6. The pipework must be clipped at suitable intervals to support it,
commencing as close to the boiler as possible.
