7. Hydraulic Installation

• The chapter 19 (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 K1200 and

17 model) or 10 litre volume (in the K2300 model) and pre-charge of 1 bar) and a 3-bar safety valve;

• Operating pressure is between 0,8 and 1,2 bar (for K1200) and 1 and 1,5 bar (for K1700 and K2300);

• To empty the unit, attach a “T-tube” with a tap to the outlet (connected to the drain); the safety valve (3 bar) outlet must also

be connected to the drain;

• 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.

7.1. Operating mode for radiator/buffer tank

IMPORTANT! The boiler is programmed to work directly for radiators, in case you want to install the boiler with a buffer or

AQS tank, we recommend changing the temperature “OFF” of the circulation pump by placing the same temperature as the deposit

or 1 °C higher than this temperature, should disable the “hYDRO Menu” modes “Modulating Pump” and “hydro independent” and

switch the mode display “Auto” to “Manual” mode and select the power 5 (Fire 5).

You must change the smoke temperatures (“Toff” and “Ton”) in the “Activation” menu. For these changes is necessary to access

the “Installer Menu” on the display, please request a password manufacture.

8. Fuel

The Free-Standing Pellet Fire operates exclusively with pellets. No other fuel sources are allowed to be used.

Only use pellets certified by standard EN 14961-2 grade A1 with a diameter of 6mm and a length of 10-30mm.

The pellets may have a maximum humidity of 8% their weight. To guarantee a good combustion, the pellets must maintain these

characteristics so it is recommended that they should be stored in a dry place.

The use of different pellets will reduce the efficiency of the unit and cause deficient combustion.

Only certified pellets should be used and a sample must be tested before buying large bulks.

The physicochemical properties of the pellets (namely, calibre, friction, density and chemical composition) may vary within specific

tolerances and across manufacturers. Please note that this may cause changes to the feeding process and, consequently, the need

for different doses (more or less pellet quantity).

The unit allows for an adjustment of +15%/-33% the pellet dosage at the start-up phase and at each power level

(please see section 9.2.7 of this manual)

WARNING!

This unit may NOT be used as an incinerator.
