Important Notes on Installation and Operation

• The stove must not be used without radiators and/or convectors installed – firing with an empty back boiler will cause it to crack.
• It is recommended that the central heating system be of the open type. A closed system requires a mandatory pressure relief valve set at 1.5 bar.
• In systems with forced circulation, it is advisable to connect the circulation pump to a UPS.
• If the system contains copper components, it must be protected against electrolysis, for example with a magnesium anode.
