Maintenance
- Clean monthly the water inlet filter.
- Always make sure there are no water leaks.
- Ask a professionally qualified technician for an inspection
to the burner, the evacuation system.
- Inspect always the flame inside the water heater for detec-
ting possible anomalous conditions.
- The gas valve is operated by the water pressure; if the wa-
ter pressure is below 0,5 bar the water heater cannot work.
- The safety valve drips when the water pressure is too
high: it will release somme drops in order to reduce the
pressure and protect the water heater.
- When more water drawings are contemporaneous (2 or 3
taps open at the same time) the flow rate of each tap can be
reduced or the temperature can decrease.
- The formation of white plumes, with low outer temperature,
is normal (white smoke).
-
When the outlet water temperature is too high:
- Reduce the temperature by acting on the selector
’D’’
of
FLAME OUTPUT; if this is not enough increase the flow
rate by acting on the adjuster ’’C’’ (WATER FLOW RATE).
-
When the outlet water temperature is too low:
- Increase the temperature by acting on the selector
‘’D’’
of
FLAME OUTPUT; if this is not enough reduce the flow
rate by acting on the adjuster ’’C’’ (WATER FLOW RATE).
- Select the most convenient type of shower head (multi-
func tion) in order to obtain the best results in terms of
temperature and quantity of water.
4.3 - ORDINARY MAINTENANCE
Freezing prevention
In case of extended periods of operation below
zero, it is suggested:
1 - Close the cold water tap.
2 - Rotate the draining valve
‘‘E‘‘
and remove it;
re-position it when all the remaining water has
been completely drained.

PRECAUTIONS:
-
When taking a shower, in order to avoid scorches, make
sure the water temperature is at an acceptable value.
-
After using water at high temperature, in order to avoid
scoches at the next use, adjust the water temperature at an
acceptable value.
The dust, in time, could cause the lockout of
the water heater and compromise the combus-
tion with increase of the carbon monoxide. It is
then necessary to call a qualified technician
for cleaning and remove the dust and soot
every six months in order to make sure the
combustion products are evacuated regularly.
The water heater must be installed vertically.
Behaviour in anomalous conditions
In case of noisy combustion, smoke at the out-
let or poor combustion, close the gas gate val-
ve, switch off the appliance and contact the
service center.
Prevention of scald injury (if the casing is
removed)
The qualified technician , after removing the
casing, must check the flame via the sight
glass.
During this operation it is important to take care
and stay at a minimum distance of 300mm.
