* 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;
