2.4 Installation in older systems and systems
requiring modifications
When installing these boilers in older systems or systems requiring
modifications, always perform the following checks:
− Make sure that the flue is able to withstand the tempera-
ture of the combustion gases and that it has been designed
and made in compliance with applicable standards. The
flue must also be as straight as possible, sealed, insulated
and not blocked or choked. See section "Combustion gas
exhaust" for any additional information.
− Make sure that the electrical supply system has been in-
stalled by a qualified electrician in compliance with appli-
cable standards
− Make sure that the fuel feed line and any storage tank are
made and installed in compliance with applicable stan-
dards
− Make sure that expansion tank(s) are big enough to contain
the additional volume generated by thermal expansion
− Make sure that the flow rate, head and direction of flow of
the pumps are suitable and correct
− The system has been washed, cleaned of mud and grime
and water seals have been checked
− A treatment system is fitted when the supply/refill water
has values other than those indicated in Paragraph "Water
Chemistry Guidelines"
