Blast tubes are to be wrapped with a glass fibre or mineral wool insulation, in order to avoid burner plate
overheating and furnace heat losses.
Important:
Even if the burner is delivered by ARCA, it has not the same warranty as the boiler. Its warranty depends on the
conditions established by its producer. Authorised personnel must effectuate the installation, the first ignition
and the burner maintenance.
