4.6. Hydraulic Installation (only for the backboiler model)
* The chapter 13 (installation diagrams) contains the optional connection diagrams for
central heating installations, with or without water heating for household use;
* The free standing pellet fire unit is equipped with a circulating pump, an expansion
vessel (6 litre volume (in the Douro 17kW model) or 10 litre volume (in the Douro 23kW
model) and a 3 bar safety valve;
* Operating pressure is between 1 and 1.5 bars;
* To empty the unit, attach a "T-tube" with a tap to the outlet (connected to the household
sewage); the safety valve (3 bar) outlet
must also be connected to the household sewage;
*The heating fluid must consist of water with an anti-rust, non-toxic product added in the
quantity recommended by the manufacturer. If the unit installation or the fluid pipes are
installed are likely to freeze, the installation engineer must add to the circulating fluid the
amount of antifreeze product recommended by the manufacturer, to avoid freezing at the
estimated minimum temperature.
