4.1 D.H.W. PRODUCTION
“25 BFT TS boiler - BT100 tank”
The preparation of hot water is guaranteed
by the glass storage tank unit with magne-
sium anode for the protection of the boiler
unit and inspection flange for its control and
cleaning.
The magnesium anode must be checked
annually and substituted when it is worn.
t is advisable to place a sluice gate at the
entrance of the D.H.W. tank unit which,
apart from the total closure, allows the
regulation of the supply capacity.
If the boiler does not produce hot water,
make sure that the air has been released
by pressing on the manual vents after
having switched off the main switch.
4.2 ADJUSTMENT OF
D.H.W. FLOW RATE
To adjust the hot water flow rate, use the
flow-rate regulator on the pressure switch
valve (7 fig. 5).
Remember that the flow rates and corre-
sponding temperatures of use of hot water,
given in section 1.3, have been obtained by
positioning the selector of the circulation
pump on the maximum value.
Should there be any reduction in the D.H.W.
flow rate, the filter installed on the inlet to
the pressure switch valve (3 fig. 5) will need
cleaning.
This may be accessed only after closing the
cold water on/off cock on the fixing jig .
4.3 ADJUSTMENT OF HEAT
OUTPUT FOR HEATING
To adjust boiler heat output for heating pur-
poses, i.e., modifying the setting made at
the factory which is approximately 16 kW,
use a screwdriver to adjust the heating
heat output trimmer (10 fig. 25).
To increase working pressure, turn the
trimmer clockwise; to reduce pressure,
turn the trimmer counterclockwise.
To facilitate the operations of adjusting heat
output, see the pressure/heat output dia-
grams for natural gas (methane) and buta-
ne or propane gas (figg. 28 - 28/a - 28/b).
4.3.1 Measuring the gas
nozzles pressure
To measure the pressure of a nozzle, con-
nect a pressure gauge to the fitting down-
stream from the gas valve (4 figure 29).
On models “25 BFT TS” , the pressure
gauge should instead be connected as
shown in figure 29/a. This connection
should also be used to test the minimum
and maximum gas pressure values. To cor-
