MAINTENANCE 

 

To keep the boiler in efficient and safe operating condition, 

we recommend you perform the following checks at least 

once a year:  

• 

Check all seals on the gas side and replace gaskets to 
restore perfect seal as required.  

• 

Check all seals on the water side and replace gaskets to 

restore perfect seal as required.  

• 

Visually check combustion and the combustion chamber; 

dismantle and clean the chamber if necessary.  

• 

Check the primary exchanger and clean it if necessary. 

• 

Check functioning of gas safety systems: Insufficient gas 

safety device (flame detection sensor for electronic ignition 

boilers) thermocouple for pilot light boilers. 

• 

Check functioning of heating safety systems: safety 

thermostat for temperature limit, safety sensor for 

pressure limit. 

• 

Check the exhaust flue safety device 

• 

Check the max. and min. modulation pressures and the 

modulation. 

• 

Check that the electrical connection conforms to the 
description in the instruction manual  for the boiler. 

• 

Check the domestic hot water flow rate and temperature. 

 
When dismantling the boiler casing, be careful when 

removing the side panels after having removed the front 

panel; the front panel is removed by undoing the lower and 

front fixing screws and then removing as shown in fig.1, lifting 

it and then pulling it away. The new side panels are 
connected to the frame by means of two hooks which 

correspond with two slots on the frame to ensure quick and 

efficient fixing.  

 

 

UNPACKING 

A. Set the packed boiler (fig. 2) down on the floor making 

sure that the arrow is pointing upwards and remove the 

sticking tape. Open the 4 flaps outwards. 

B. Turn the boiler 180° supporting it by hand. 

C. Lift the boiler with the packing pieces positioning it 

vertically in order not to damage the lower corners of the 

casing. Remove the packing pieces. Lift the boiler by 

holding it at the back and proceed with installation.  

 

N.B.

 It is recommended that the boiler be unpacked before 

installation. The manufacturer cannot be held responsible for any damage caused to the boiler due to incorrect handling of the 

boiler. 

 

IMPORTANT! 

The packing materials (cardboard) are recyclable. 

 

IMPORTANT! 

The inner packing materials (plastic bags, polystyrene foam, nails etc.) are potentially dangerous and must not be left within 

reach of small children.
