3.11 - WATER AND ELECTRICAL CONNECTION DIAGRAMS WITH OPTIONAL CONTROL
PANEL BOARD, WITHOUT HOT WATER STORAGE TANK
Foreword!
The diagrams shown here below may be customized.
For particular requirements, please contact our After Sales Service.
The GASOGEN G3 2S boiler’s standard control panel
automatically switches off the fan and the recirculation pump if
the boiler temperature, (once 30 minutes have passed from
closing the upper loading door for firing the boiler), does not
reach 65°C (
minimum temperature
).
In this case, or when the wood finishes, the auxiliary boiler will
start firing automatically, provided the selector 22 of the panel
board is on (
0
) and the burner switch 23 is in pos.
II
, 30 minutes
after the wood fired boiler temperature falls below 60°C.
The wood fired boiler’s door must be kept closed.
The wood fired boiler, in this case, will be excluded and it will
be possible to restart it after opening the door in order to load
new wood.
If the burner switch 23 is always kept on pos.
0
), the back-up
boiler’s burner will be always excluded.
Obviously, to permit operation of the back-up boiler, the control
panel must be in the ON position.
The GASOGEN G3 2S boiler’s control panel (and operation
cycle) can be reset only after the upper door is reopened for a
new restart, or by turning the mains switch 11. OFF and then
ON.
Central heating installation with temperature controlled via a motorized mixing valve.
DHW is produced via a coiled hot water storage tank or plate heat exchanger with an independent installation system
and dedicated loading pump.
The two boilers are hydraulically connected in series, with the wood fired boiler system flow connected to the oil/gas
fired boiler’s system return.
There is no need to install a diverting valve, or DHW storage tank loading pump; the DHW tank can be incorporated in
the oil/gas fired boiler.
In the summer, DHW production can be supplied only by the oil/gas fired boiler.
The heating circuit water flows through both the boilers and, in this case, the heat losses are very important.
IMPORTANT: During the installation phase make sure the jumpers’ settings in the control panel are as indicated in
chapter 5.2.
The logic operation of the GASOGEN G3 2S boiler’s control
panel, will switch off the fan and the recirculation pump once
the wood finishes.
The central heating system pump will operate only after the
boiler exceeds the minimum temperature of 65°C.
When the boiler temperature falls below 65°C, the central
heating pump will shut down.
The D.H.W. storage pump will operate in priority compared to
the central heating pump.
The
flow sensor (Tc)
must be always placed in the boiler’s
bulb holder (
see fig. 17
).
D.H.W. production will be given priority via the storage tank
loading pump (PR), controlled by a changeover thermostat.
The eventual D.H.W. recirculation pump must be connected to
the mains independently from the GASOGEN G3 2S boiler’s
control panel.
During the summer season we recommend that DHW is
requested via the back-up boiler, or with the wood fired boiler,
provided the indications given on paragraph 6.11, page 59,
are strictly followed.
