3.6 Installation in older systems and systems
requiring modications
When installing these boilers in older systems or systems requiring
modications, always perform the following checks:
− Make sure that the ue 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
ue 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 qualied 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 ow rate, head and direction of ow 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 tted when the supply/rell water
has values other than those indicated in section “Water
Chemistry Guidelines”
