Improper usage excludes any liability claims. This product complies with the relevant directives and is therefore labelled with the CE mark. The Declaration of Conformity is available upon request, please contact the manufacturer. Only use PAW accessories with the product. 05/2023 993x03x3x-mub-en - V03...
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].
You can mount the PAW HeatBloC® directly onto a wall bracket or under/on a PAW modular distribution manifold. With transition connections, PAW HeatBloC®s can also be mounted under/on PAW modular distribution manifolds of other dimensions.
Product description 3.2 Function Boiler charging set for the 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 7
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. Undesired circulation, which could lead to overcharging of the domestic water tank, can thus be prevented.
Product description 3.3 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.

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.

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).
Product description 3.4 Check valve The HeatBloC® is equipped with a check valve (G-2) in the housing of the thermo controller (A-2). The check valve can be opened manually. Operation During operation, the marking must be directed to "Z". The check valve is closed. ●...
The HeatBloC® K36E can be mounted under/on a PAW modular distribution manifold or on a wall bracket. The K36E is prepared for assembly under a PAW distribution manifold DN 25 when it is delivered. If you want to mount the K36E on a PAW modular distribution manifold, remove the coupling piece for overhead installation (G-3).

- Fix the wall bracket to the wall with the enclosed screws and washers. - Mount the modular distribution manifold with the PAW mounting brackets. You can mount the - Insert the clip springs in the lower ball HeatBloC® K36E directly on the connections of the valves.
Mounting and installation [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. Push the union nut ② and the cutting ring ③ onto the copper pipe ①.
