N.B.
It is recommended when making one or more adjustments, with the screws
A-B
, to take special
care and use a screwdriver.
The gas pressure measured at points 1 and 2 should be read at least 30 seconds after making
the adjustment.
Adjusting the heating
'
t by changing the delivery/head of the circulator.
The temperature drop
'
t (difference in temperature of the heating water between the system delivery
and return) must be less than 20°C and this is obtained by changing the delivery-head of the circulator
with its 3-speed selector. Note that on increasing the circulator speed,
'
t decreases and vice versa.
Pressure adjustment of the water in the heating system
The pressure adjustment of the water in the heating system, read on the thermometer water gauge “
1
”
(fig. 1) of the control panel, must be made as described in paragraph 2.3. If the system is the open tank
type, it is sufficient to check the water level periodically.
Tap water temperature adjustment
The tap water temperature is adjusted with the knob of the boiler thermostat “
4
” (fig. 1). Remember
that the maximum travel of the knob permits temperature adjustment from 15 to 60°C.
