To connect the heating stove to a DHW system it is advisable to contact a competent technician in order to best
optimise the plumbing connections and the performance of the entire system without compromising stove operation.
For the connection to the DHW circuit it is necessary to install a monostable 3-way valve outside the stove whereas
the circuit is not functional with the DHW pump.
To connect the DHW system 3-way solenoid valve it is necessary to request the optional: supplementary electronic
board model 'I055' for management of commands as well as possible software upgrading.
During stove transport the gaskets in the plumbing system may come loose and/or break, causing water
leaks during normal operation; therefore make sure to check the tightness of the circulating pump and
heating chamber connection rings and vent the residual air during water filling and after the first hours of
operation.
