    2 Safety instructions 2 Safety instructions The installation and commissioning as well as the connection of electrical components require technical knowledge commensurate with a recognised vocational qualification as a fitter for plumbing, heating and air conditioning technology, or a profession requiring a comparable level of knowledge [specialist].
  • Page 6: Product Description

    The pump can be isolated by means of the ball valves and can thus be maintained without draining of the system. You can mount the PAW HeatBloC directly onto a wall bracket or under/on a PAW modular distribution manifold. With adaptor connections, PAW HeatBloCs can also be installed on PAW distribution manifolds with other dimensions.
  • Page 7: Function

    3 Product description 3.2 Function K36E boiler charging set for return flow temperature maintenance of solid fuel boilers, wood firing and stove heating systems The boiler charging set prevents the temperature in the boiler from falling under the dew point, thus reducing the contamination of the boiler.
  • Page 8 3 Product description The boiler charging set can be mounted under/on a  distribution manifold. In this system the pump exerts a pressure on the entire installation. When the overflow valve in the thermo controller is open, the pressure can be reduced via the valve.
  • Page 9: Thermo Controller

    3 Product description Thermo controller The thermo controller is equipped with an overflow valve and a thermal control valve. Overflow valve In systems with a distribution manifold the pump of the boiler charging set exerts a pressure on the entire installation. When the overflow valve in the thermo controller is open, the pressure can be reduced via the valve.
  • Page 10 3 Product description Thermal control valve The thermal control valve serves as a bypass in the startup phase. 1. When the temperature of the water in the boiler circuit is lower than the opening pressure of the thermal control valve, the valve is closed and thus the line to the consumers.
  • Page 11 3 Product description Change of the flow line [specialist] 1. Take off the thermometer handles (C-2, D-2) and remove the insulating front shells. 2. Take the heating circuit out of the insulating back shell. 3. Take off the union nuts at the thermo controller (A-2).
