Hydraulic Installation
* You can find in chapter 13 (installation diagrams) possible connection schemes in
the context of a central heating installation, with or without domestic water heating;
* The minimum connection temperature of the circulation pump should be 60°C. It
is advisable to install an anti-condensation valve to avoid condensation phenomena
inside the boiler;
* The pump must be applied in the return circuit, where the temperature is lower;
* The thermostat should be diving, and just like the combustion regulator, it should
be applied to the hot water outlet pipe;
* Solzaima advises an open pot installation, and the pipe connecting it to the boiler
return should not have a diameter of less than 20 mm. No vents should be installed;
* If the installation option is for closed expansion vessel, it should not be sized
according to the installation and the safety valves should be 3 bar (suitable for use
up to 90°C). An additional pressure and temperature safety valve (3bar / 90°C) is
recommended.
* For the purpose of emptying the appliance, a tap shall be placed at one of the exits
provided for that purpose in the lower area of the appliance;
* The heat transport fluid must be water with the addition of an anti-corrosion, non-
toxic product and in the quantity recommended by the product manufacturer;
* The automatic combustion regulator prevents the water temperature inside the
appliance from rising too high if the thermal power removed is lower than that
produced. It does this by reducing the primary air intake and therefore decreasing
the combustion speed. This is an important protection and safety mechanism,
preventing water from boiling and/or the pressure from increasing too much, by
making emergency safety devices work. The regulator must be placed on the thread
indicated in the diagram and must be adjusted to close the primary air inlet door at
80°C -
in order to achieve proper operation of any of the equipment referred
to in this manual, the automatic combustion regulator must always be
installed.
* If there is a risk of freezing in the space in which the recovered is located or in the
fluid lines, the installer shall add antifreeze to the circulating fluid in the proportion
recommended by its manufacturer to avoid freezing at the minimum absolute
temperature expected.
* Never connect the stove without the hydraulic circuit being filled with fluid and in
full operation.
