SENKO cookers 2P extra rustik and glass – Instruction manual 19
Installation of an approved safety valve with opening overpressure
set to 2,5 bar is mandatory in closed systems. Safety and expansion
conduits must not have any kind of block elements.
It is necessary to install the deaerating valve. When filling the boiler
and the radiator system it is necessary to open the mixing valve, if one had
been installed; adequately deaerate the boiler and the heating system.
The mixing valve (7 – figure 9) maintains the boiler temperature at
minimum the 60C, thus preventing the boiler from condensation. If
one had not been installed, it is necessary to ensure firing conditions that
will prevent boiler condensation. Condensation may appear at the
beginning of the firing process or due to insufficient feeding.
Pipeline thermostat which activates the circulation pump must not
be adjusted to values lower than 60C !
