2.8 LEVANA AQUA 2.0 water installation
Water side connection
The water pipes can optionally be laid to the rear (installed in the
factory) or to the bottom through the oor.
For laying through the oor, you must remove the lower rear wall
and adjust the mounting for the ow and return ow accord-
ingly. For laying of the water pipes through the oor, as well as for
removal / installation of the rear cladding, follow a similar procedure
to that which is set out in the “Combustion air nozzles for connec-
tion from the bottom chapter.

Important information for integration of the pellet re-
place into the heating system and/or domestic cooling
water system:
ū The water connections and the electrical work may only be car-
ried out by expert technicians.
ū We recommend the “Olsberg installation unit” (item no.:
23/5591.9250) for integration into the heating system and/or do-
mestic cooling water system. Observe the separate manual for
this unit here.
ū In addition to the necessary safety components, a return ow in-
crease valve which increases the return ow temperature to at
least 55 °C must always be installed (integrated into the “Olsberg
installation unit”).
ū An outlet tap must be installed in the bottom section of the wa-
ter circuit.
ū A buer must be integrated into the heating system for ecient
and fault-free operation of the LEVANA AQUA 2.0 pellet replace.
As a guideline for the storage volume, approx. 60 litres should be
provided per kW of heating output (approx. 500 litres).
ū For ecient operation of the pellet replace, it is strongly rec-
ommended that both buer sensors (top and bottom) be
connected!
Clean the heating system before hydraulic connection of the pel-
let replace through ushing in accordance with DIN EN 14336
(Heating systems in buildings – Installation and commissioning
of water based heating systems) so that the function of the pellet
replace is not endangered!
Proof of cleaning must be provided in the event of possible war-
ranty services from Olsberg.
The pellet replace may never be operated without water.
The locally applicable regulations and technical rules must also al-
ways be observed!
Venting at the vent valve
After connection of the ow and return line and lling with wa-
ter, the system should be vented at the vent valve for the pellet
replace.
Check all water connections on the pellet replace for leaks!
