The insurance certificate pertains to JASPI DUO, TRIPLEX, ECOWOOD, YPV 40, and VPK hand filled solid-fuel boilers manufactured by our company. We hereby certify that the entire development of the above boilers meets the safety requirements as in Chapter 2.3 of Directive 97/23/EU.
Under no circumstances should the boiler be used whilst not fully filled with water. A mechanical boiler cooling valve must be fitted to the indirect cooling coil at the rear of the boiler. This can for example be a Jaspi TSK / STS valve shown here;...
AUTOMIX TERMOVAR FLUE GAS THERMOSTAT For solid fuel boiler pump control FUNCTION The TERMOVAR flue gas thermostat controls the heat loading unit or transfer pump between the thermal store and the boiler. When the flue reaches the selected temperature, the Metal washers thermostat starts the pump and the heat is transferred from the boiler to the thermal store, heat exchanger or...
A heat loading unit shown on the page 5 is designed to prevent this happening. If despite the heat loading unit being installed, the boiler still condensates, then check the functioning of the return thermostat and change to the correct one if needed. We recommend a 60 - 80°C return temperature for the YPV 40 boiler.

Heavy construction and high grade steel gives higher thermal mass and extended service life. In addition of logs, the YPV 40 can burn large wood pellets, briquettes, heat logs and even coal. If using coal, the boiler needs more regular cleaning as the the coal deposits can block the aitr flow through the cast iron burning grate.
