5 INSTALLER IMPORTANT POINTS
Please read all instructions before fitting this appliance
•
The installer shall instruct the user on the operation of the boiler, safety devices
contained within the boiler and on the location of the filling loop and how to re-pressurise
the system if the water pressure falls.
•
The installer should then hand over the instructions indicating the included Benchmark
Commissioning Checklist that has been completed.
•
It is required under Gas Safe Regulations for the installation to be notified to Building
Control (Gas Safe Notifcation).
•
Before proceeding to commission the boiler check the gas inlet pressure is 20mbar (NG)
or 37mbar for Propane.
•
Combustion analysis with a correctly calibrated and certificated analyser is essential for
safe commissioning of the boiler.
•
A pressure reducing valve set to 3.5 bar must be fitted if supply mains pressure is above
4 bar.
•
A suitable scale reducer must be fitted if water hardness is above 200 ppm.
•
The user should be instructed to keep the instructions in a safe place for servicing and
future reference.
•
It is important to keep the boiler clear of dust during the installation. In particular, do not
allow debris to enter the flue connection at the top.
•
Before fitting the boiler ensure that the pipe work that you are installing is connected to
the appropriate connections on the boiler.
It is important to thoroughly flush the water circuits, after isolating the boiler, in order to
remove any fluxes and debris from them. This should be done particularly where boilers
are being fitted to existing radiator circuits (please refer to current Standard Codes of
Practice).
•
BS 7593:2006 for the details to clean DHW and Central heating system.
•
This boiler has been factory set but adjustment may be required to the heating input in
order to match the individual heating demand. This can be done by changing parameter
3 (= max. power CH) or parameter 4 (= max. power domestic water).
•
Please do not use the pressure relief valve as a means of flushing the system.
•
Remember that after hot water draw of a possible delay may occur before the heating
system will fire up.
•
All fluxes, residues and cleaner must be flushed from pipe-work and radiators prior to
commissioning.
•
External expansion vessels are best connected water side downwards to allow correct
draining/cleaning of system and to prolong the life of the vessel diaphragm.
•
Note: an anti-cycle delay time can be set up to a maximum of 15 minutes by adjusting
parameter P as described in § 10.3.
•
If you experience any problems please refer to the installation and commissioning
guidelines within the boiler instruction manual. If necessary, please contact Intergas
Heating Ltd (See § 1.8).
Remember it is a requirement to complete the Benchmark code of practice logbook before
leaving the installation. You are also required to register the boiler through the Gas Safe
registration scheme.
