Scope of these instructions These instructions describe the installation, commissioning, function and the operation of the HeatBloC K36E DN 25 and DN 32. For other components of the installation, such as the pump, the controller or the modular distribution manifold, please observe the instructions of the corresponding manufacturer.
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].
The pump can be isolated by means of the ball valves and maintenance work on the pump can thus be carried out without draining the boiler circuit. 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.
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.

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.
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 an initial pressure on the entire installation. If the overflow valve of the thermo controller is open, the pressure can be reduced via the valve.

3 Product description Thermal control valve The thermal control valve serves as a bypass in the startup phase. 1. If the water temperature in the boiler circuit is lower than the opening temperature of the thermal control valve, this valve is closed and thus also the line to the consumers.

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 group of fittings out of the insulating back shell. 3. Loosen the union nuts at the thermo controller (A-2).
3 Product description Check valve The HeatBloC is equipped with a check valve (G-2) in the thermo controller (A-2). It can be opened manually. Operation During operation, the marking must be directed to "Z". The check valve is closed. ...
4 Assembly and installation [specialist] 4 Assembly and installation [specialist] The HeatBloC K36E can be mounted on/under a PAW modular distribution manifold or on a wall bracket. The K36E is prepared for assembly under a distribution manifold DN 25 when it is delivered.

(G-3) to the wall bracket. Only for the assembly under a modular distribution manifold Mount the distribution manifold on the PAW wall bracket. You can mount the heating circuit K36E directly on the connections of the manifold. Remove the plugs in the pipe connections of the modular distribution manifold if necessary.
5 Scope of delivery [specialist] 4.2 Accessories: Cutting-ring compression fitting (not included in the scope of delivery) The connection to the heating installation can be carried out fast, pressure-proof and without soldering if you use the optionally available compression fittings. 1.
