7.4 Hydronic Installation
* The chapter 16 (installation diagrams) contains the optional connection diagrams for central heating installations, with or
without water heating for household use;
* The boiler model pellet stove is equipped with a circulating pump, an expansion vessel (6 litre volume in the K1200 & K1700
models ,10 litre volume in the K2300 model) and a 3-bar safety valve; A calculation must be made in each individual installation to
check the required size of the expansion vessel and additional vessel added if required.
* The product must be installed on a sealed system. Operating pressure is between 1 and 1.5 bars;
* To drain the boiler, attach a "T-tube" with a tap to the waste water drain the safety valve (3 bar) outlet must also be connected to
the waste water drain;
*The heating fluid must consist of water with a corrosion inhbitor non-toxic product added in the quantity recommended by the
manufacturer. If the stove installation or the fluid pipes are installed are likely to freeze, the installation engineer must add the
correct amount of antifreeze product recommended by the manufacturer to circulating fluid to avoid freezing at the estimated
minimum temperature.
8 Fuel
The boiler pellet stove must be operated exclusively with pellets. No other fuel may be used.
Use only pellets certified by standard EN 14961-2 grade A1, with a
6 mm diameter
and measuring
between 10 and 30 mm long
.
The pellets must not have a moisture content in excess of 8% . To guarantee a good combustion, the pellets must maintain
these characteristics so they should be stored in a dry place.
The use of different pellets will reduce the efficiency of the stove and cause poor combustion.
You should always use certified pellets and must test a sample before buying large bulk loads.
The physical/chemical properties of the pellets (i.e. the calibre, friction, density and chemical composition) may vary within
specific tolerances and according to each manufacturer. Please note that this may cause alterations to the feeding process
and, consequently, the need for different doses (more or less pellets).
The stove allows the dose of pellets to be adjusted during start-up and at power levels by ± 25%
Warning : The stove must NOT be used as an incinerator
