3.2.8 Measuring combustion efficiency 

Perform the following to determine combustion efficiency.  
- measure the combustion air temperature. 
- measure the temperature of the flue gas and the percentage of  
  CO

2

 taken through the holes in the flue gas duct.  

Take  these  readings  with  the  heating  unit  running,  after  making 
sure the Bacharach index is less than 1.

3.2.9 Connecting to the power mains 

The  heating  unit  must  be  connected  to  a 

230V  –  50  Hz

  power 

supply.

The power cable must be made of rubber.

Do not use PVC cables, which have low temperature resistan-
ce and tend to deteriorate quickly. 

Make sure all the wires are connected correctly.

During  installation,  comply  with  the  applicable  standards 
and  laws,  which  should  be  taken  as  incorporated  in  full  in 
this manual. 

A two-pole switch must be fitted before the heating unit to allow 
maintenance to be carried out in safety.  The power line must be 
protected by a differential magnetothermal switch with a suitable 
breaking capacity. 
The mains supply must be properly earthed.  

This  safety  precaution  is  mandatory.  In  case  of  doubt,  have 
the whole system checked carefully by a qualified electrician. 

This  safety  precaution  is  mandatory.  In  case  of  doubt,  have  the 
whole system checked carefully by a qualified electrician. 

The manufacturer can in no way be held liable for damage or 
injury caused by failure to earth the system properly. The DHW, 
CH and fuel pipes are not suitable for earthing purposes. 

3.2.10 Plumbing connections 

CENTRAL HEATING

Before installing the heating unit we recommend you clean the sy-
stem to remove any impurities from the various components which 
might damage the circulating pumps or the heat exchanger. 
The  central  heating  flow  and  return  pipes  must  be  connected 
using G 3/4 fittings.  
When determining the size of the heating circuit pipes, it is essen-
tial to take into account the load losses induced by the radiators, 
any thermostatic valves, radiator cut-off valves and the configura-
tion of the system.

DOMESTIC HOT WATER

The flow and return pipes must be connected to the respective G 
1/2” fittings on the heating unit. 
The mains pressure must not be more that 6 bar, otherwise a pres-
sure reducer needs to be provided. 
The pressure in the DHW circuit should be between 3 and 4 bar. 

The hardness of the mains water determines how often the heat 
exchanger coil needs to be cleaned.

ATTENTION
- If the water is particularly hard it may be necessary to provide  
  a domestic water softener with a device for dosing a specific  
  product for treating drinking water in compliance with the 
  applicable laws.  It is always advisable to treat water with a  
  hardness of more than 20°F. 
- Due to its pH value, water supplied from normal water 
  softeners may not be compatible with some components of  
  the heating system. 
- The safety valves should be connected to a drain, otherwise  
  the boiler room may get flooded when they operate.  

The manufacturer can in no way be held liable for damage caused 
by failure to take these basic safety precautions. 
Picture  14  shows  the  plumbing  system  diagram  of  the  heating 
unit. 

3.3. Filling the Central Heating Circuit 

When  all  the  connections  have  been    made,  the  CH  circuit  can 
be filled with water. This must be done carefully in the following 
order: 
- Open all the radiator air valves and the automatic relief  valves on  
  the heating unit. 
- Remove the front panel by pulling and lifting it toward the out-
side.
- Load the boiler by opening the tap anticlockwise (as shown in 
pic. 2) to let the water in.
- Close the radiator air valves as soon as water starts to come out. 
- Using a gauge, check that the pressure is 1/1.3 bar.  
- Turn off the filling tap and open all the radiator air valves again.  
- Switch on the heating unit and allow it to heat up, then switch it  
  off and bleed all the radiators again. 
- Allow the system to cool down and check the water pressure is  
  within the correct range (1/1.3 bar).

WARNING

As far as domestic heating systems treatment of water is 
concerned, in order to optimize performance and safety, to 
preserve these conditions over time, to ensure long-lasting 
regular  operation  of  auxiliary  equipment  as  well,  and  to 
minimize  energy  consumption,  thereby  integrating  current 
laws and standards it is advisable to use specific products 
that are suitable for multi-metal plants.
