Wind shield terminal:
A wind shield terminal must be installed to avoid fume back
flow.
Chimney draught
: The installation must ensure the generation of a draught of 25 Pa
(0,25 mbar) when the unit is hot and operating at its maximum power.

Hydraulic installation
* Chapter 12 (installation diagrams) contains the optional connection diagrams for
central heating installation, with or without hot water system for domestic use;
*
The minimum temperature at which the circulator pump is activated should be
60°C. We recommend that an anti-condensation valve is installed to prevent the risk
of condensation build up inside the chamber;
*
The pump must be mounted at the recirculation circuit where the temperature is
lower;
*
A boiler thermostat, or aquastat, should be used and mounted at the hot water
outlet pipe, as with the combustion regulator;
*
Solzaima recommends that the installation uses an open expansion vessel, with a
20-cm diameter pipe as a minimum, to connect the vessel to the boiler's recirculation
circuit. No vents are required;
*
If the installer chooses to perform the installation using a closed expansion vessel,
the vessel dimensions must consider the size of the installation, using 3-bar safety
valves (adequate for temperatures up to 90°C). Additionally, we recommend the
additional installation of a pressure and temperature safety valve (3bar / 90°C).
*
To drain the boiler, a tap should be attached to one of the outlets provided for this
purpose at the bottom of the unit;
*
The heat transfer fluid to be used should be water with an additive corrosion
inhibitor, non-toxic product, in the quantity recommended by the product
manufacturer;
*
The combustion auto-regulator prevents the water temperature inside the appliance
to get too hot, when the removed heating power is lower than the produced heating
power. This is achieved by reducing the primary air admission which reduces the
combustion speed. This is an important safety feature that prevents the water to boil
and/or the pressure to get too high, by triggering the emergency safety features. The
regulator must be attached to the screw thread provided for this purpose, as shown
