SIME SUPPORT THE BENCHMARK
INITIATIVE
All relevant sections of the logbook must be
filled in at the time of installation and there-
after service information on the back page
of the logbook. Commissioning of the boiler
is not complete until the logbook is filled in.
4.1
FILLING THE WATER SYSTEM
– Open the flow and return valves (27 -
28 fig. 2).
– Loosen the automatic air vent cap (13-
21 fig. 2).
– Open all radiator valves and system air
vents. Fill the system with water using
one of the approved methods described
in section 2.3.2 t o about 0.5 bar
greater than the system design pres-
sure. Close all air vents. Do not close
the A.A.V. (13-21 fig. 2).
– Check the system for water soundness.
– Completely drain the appliance and heat-
ing system, thoroughly flush the system,
and refill the system design pressure.
– Before refillimg check and clean the Aqua-
guard filter (4.9).
4.2GAS VALVE
The boiler, is equipped standard with the
HONEYWELL VK 4115V gas valve (fig. 18).
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 17 kW,
use a screwdriver to adjust the heating
heat output trimmer (6 fig. 15).
To increase working pressure, turn the
trimmer clockwise; to reduce pressure,
turn the trimmer counterclockwise.
To determine boiler heat output setting (for
both natural gas and propane gas), check
Hertz value shown in
Table 6
(fig. 19.)
4.4
CALIBRATION PROCEDURE
IN HEATING PHASE
USING HERTZ (fig.20)
1) Turn heating manometer knob to maxi-
mum. Check that water temperature at
heating system is lower than 75°C.
2) Turn the trimmer (6) anti-clockwise as
far as it will go to minimum power.
3) Open completely the gas capacity step
(7) by turning the screw anti-clockwise
until end of stroke.
4) Adjust trimmer (4) and check that Hertz
value is between 68 and 72.
5) Adjust the gas valve OFF-SET (8) in order
to achieve a C0
2
value of 10.8% for
natural gas or of 10.9% for propane. To
increase C0
2
value, turn the screw
