Special delivery condition (partially disbanded)
For special circumstances like restricted space to bring the boiler into the heating room, the size of the boiler can be
reduced by detaching additional components to the ones as described in section “Standard delivery condition”. The
assembly of these components require additional assembly time of approximately 6 hours.
The following additional objects will be delivered disbanded:
- The heat exchanger and the combustion chamber are separate
- No brickwork inside the heat exchanger and combustion chamber
- No insulation and panels are attached to the combustion chamber
Measurements of the largest part for reduced boiler size
Special delivery condition (fully disbanded)
For special circumstances like heavily restricted space to bring the boiler into the heating room, the size of the boiler
can be reduced by detaching additional components to the ones as described in section “Standard delivery condition”
and “Special delivery condition partially disbanded”. The assembly of these components require welding and additional
assembly time of approximately 20 hours.
The following additional objects will be delivered disbanded:
- The heat exchanger is a separate piece
- The flue gas collector is detached from the heat exchanger
- The boiler door is detached from the heat exchanger (welding required)
