PRESSURE AND RETURN PIPE
Outputs of the pressure and return pipes on the boiler are 1'' and you cannot reduce them or taper to the first bifurcation.
Use a 1’’ steel pipe or a copper pipe with the outside diameter of Ø28mm or greater.
When installing, strictly observe the slopes of pipes as they need to be at 0.5% (5mm. per meter of pipe) and the venting
system (boiler, pipes, radiators).
Set up a thermo hydrometer at the pressure line to show the water pressure in the system and the water temperature at
the back end of the boiler.
BUILT-IN COMPONENT OF THE STOVE
- In the stove, there are the following built-in components:
- Safety valve
- Circulation pump
- Automatic air valve
- Expansion container and
- Charging and discharging tap
For this reason there is no need to install these components again. The stove is complete, which is a great advantage most
all of because there is no need for additional space for the listed components.
SAFETY VALVE
It is set up under the lid of the stove on the pressure line. Input connection is R1/2". It opens with water pressure of 2.5 bar.
You can get to it by removing the right lateral side, when you are looking at the stove.
The output safety valves whose connection protrudes through the rear wall above the pressure line should be put into the
sewer pipes.
CIRCULATION PUMP
A high-quality Wilo RS 25/6 – circulation pump has been built into the stove on the return line of R1”. The power of the
pump is 93W. It is turned on and off by the electronics by the set water temperature.
The pump shaft has to be in a horizontal position. For this reasons, when connecting with the installation make sure that
the pump does not turn around! Firmly hold galvanized bolt at the end of the back side.
You can reach the pump by removing the left lateral side, when you are looking at the stove.
Note:
If the stove and the pump have been idle for a long time (a month, for example), the pipe shaft can stick to the base, it may
not move the water, or it can burn out. If when starting the stove when the water in the boiler heats up the water pump does
not start, if the radiators do not heat up when the set temperature is reached, if you do not hear the murmur of water (moving),
or if the boiler temperature rises and radiators are not warming, remove the left lateral side as indicated in the previous
