collector/chimney
• Air intake can take place in the boiler room, on condition that the room is properly ventilated according
to the standards in force. Be careful to remove air blanking plus from every single module.
• It is emphasized that every Econcept 50 module is equipped with all its own necessary and/or compulsory
safety devices. In particular, every Econcept 50 device is equipped with its own safety valve against
overpressure (6bar), low water pressure switch, safety stat, limit stat. In case of overheating, absence of
water or absence of circulation into the boiler, safety devices cause the switch-off or the locking out of
boiler, preventing its running.
Cascade control system and electric connections
• Use the electronic control box sequence 1KWMH18A (optional) for the automatic management of cascade
devices. Every control box allow the management from 2 to 5 Econcept boilers in cascade. More control
boxes can be connected one to another in parallel to allow further expansions (10, 15, 20 … Econcept 50
boilers in cascade). For electric connections, see the instruction provided in the kit.
Flue Evacuation
• The collector, the flue and the chimney must be correctly sized, designed and built to the standards in
force. They must be made of appropriate material for the purpose, that means resistant to high
temperatures and corrosion, smooth inside and hermetically sealed. In particular, connections must be
condensation-tight. Furthermore, provide suitable condensation drainage points, connected to a trap.
• Connect the flue outlet (Ø 80) of single modules, as shown in figure, is being careful to respect diameters
of collectors and chimneys written in the table below.
