4 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 hand over the installation and user instructions upon completion with the
completed Benchmark Commissioning Checklist.
► The service engineer must complete the service record on the Benchmark Checklist aer each
service.
► It is required under Gas Safe Regulations for the installation to be notified to and registered with
Gas Safe, Intergas and 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.
► In hard water areas where the PH is 200ppm or above, appropriate protection actions must be
taken in accordance with BS 7593 in line with building regulations Part L.
See also Guarantee Provisions on page 75, point 4.
► 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, aer 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).
► Intergas recommend water treatment in accordance with the Benchmark Guidance on Water
Treatment in Central Heating Systems, we recommend the use of FERNOX, SENTINEL or ADEY
inhibitors. It is most important that correct concentration of water treatment is maintained
for the life of the boiler, a water sample is required on installation and to be verified by the
aforementioned manufacturers should we attend a warranty call a water sample may be required
to keep the warranty valid. (BS 7593:2006)
► 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 P010 (= max.
power CH) or parameter P070 (= max. power domestic water).
► Please do not use the pressure relief valve as a means of flushing the system.
► Remember that aer 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
P036 as described in §8.3.
► 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).
