Installation and Servicing
5.4 INSTALLATION PROCEDURE
Refer to the installation manual for the boiler.
5.4.1 Mounting Frame
Place the frame kit in the required position. Do not secure the
frame to the floor until the installation process has been completed
as adjustments to the position of the frame may be necessary.
5.4.2 Flow / Return Connections
Attach the upper parts of the flow and return connections to the
boiler. Refer to section
3.6
5.4.3 Boiler
Mount the boiler onto the frame kit.
5.4.4 Fitting Gas Connection Kit
Note:
Gas Isolation Valve is supplied with the boiler.
1. Fit the conical male adapter to the gas isolation valve.
2. Fit the gas isolation valve assembly to the boiler gas
connection ensuring the sealing washer is fitted.
3.
Fit the flexi gas pipe to the isolation valve.
5.4.5 Condensate Connection
Fit the condensate siphon to the boiler and pipe to drain,
following the recommendations contained in the boiler
Installation instructions.
5.4.6 Pressure Relief Connection
Ensure the boiler pressure relief valve is connected and
piped to safety.
5.4.7 Flow / Return Pipework / Plate Heat
Exchanger
Assemble the remaining sections of the flow and return pipework
to the plate heat exchanger and connect up the boiler circuit.
Where the boiler circuit is circulated by an external pump ensure
that the pump is fitted in the correct orientation with flow going
upwards into to the boiler.
Where the boiler has an internal pump ensure that the pump spool
piece is installed.
5.4.8 Filling / Dosing
Fill the boiler circuit to a static pressure of between 1 – 1.5 bar
using the pressure gauge on the boiler circuit pipework. The boiler
circuit should also be dosed with appropriate water treatments as
noted in the boiler installation manual.
It may be necessary to circulate the completed boiler circuit to
purge any residual air from the circuit until a stable pressure
reading is obtained. Ensure that all joints and connections show
no visible signs of leakage.
