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 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)
 Check functioning of heating safety systems: safety thermostat for temperature limit,
 Check the exhaust flue safety device
 Check that the electrical connection conforms to the description in the instruction manual for the
boiler.
UNPACKING
A. Set the packed boiler 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 and 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.
