Instruction for the installer
Boiler installation
Installation conditions
• an appropriate power supply,
• an efficient electrical installation which has been completed in accordance with the binding norms of electric installation,
• wet central heating system equipped with an appropriate expansion vessel made according to the binding norms of hydraulic
installation,
• the heating installation needs to be flushed thoroughly before the installation,
• the boiler must be protected from dirt by using a magnetic filter,
• do not install any barrier fittings (e.g. valves) on the outlet of the safety valve,
• this appliance must not be installed in a humid place or in a place exposed to the danger of explosion,
• if the boiler is to co-operate with an under-floor heating system protecting fittings must be installed (fig. 2b or 3).
A magnetic filter must be installed on return pipe of central heating installation system (before
boiler inlet). The filter must be installed in horizontal position, accordingly to flow direction (see
arrow on the filter body), with the magnetic insert chamber to the bottom.
