Instructions for the installer

Simplified water connection layout between the wood fired boiler, accumulator and DHW production, and the back-up
boiler linked together (see figs. 35 and 36)

IMPORTANT: During the installation phase make sure the jumpers settings in the control panel are as indicated in
chapter 5.2.

The GASOGEN G3 2S boiler’s 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

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.

The operation logic of the GASOGEN G3 2S control panel, will
switch off the fan and the recirculation pump once the fire 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 thermal inertia of the wood fired boiler will always be
discharged on the central heating circuit.
The

flow sensor (Tc)

must be always placed in the boiler’s

bulb holder (

see fig. 17).

The

return sensor

must be always fitted (for the positioning

see fig. 20); see installation mode in paragraph 5.5.7.

The jumper 71-72 on the PCB must be removed.

The introduction of an accumulator in the system of (see sizing
on page 27), enables you to obtain a high seasonal efficiency
from the GASOGEN G3 2S boiler and a better management of
the heating system, as well as a longer life span of the boiler,
by reducing the temperature peaks, caused by inconstant
drawing-offs from the heating system itself.
Moreover, the accumulator makes you save a lot on your gas
bill.

This type of installation is particularly effective during the “mid
seasons”, since it avoids having to use reduced wood fire loads
and, consequently, fire the GASOGEN G3 2S under its
minimum output, with the possibility of creating flue condensate,
which would damage, in a short time, the wood fired boiler.

The

diverting valve (UV)

, will direct the system returns towards

the boiler ready to operate in that moment, thus reducing the
heat losses.

The temperature of the accumulator, superior to 50-55°C, will
prevent the back-up boiler’s burner firing.

La produzione di a.c.s. sarà gestita in priorità tramite la pompa
di carico bollitore (PR) comandata da un termostato in scam-
bio, la pompa di ricircolo dell’impianto sanitario dovrà essere
collegata alla rete elettrica indipendentemente dal pannello
strumenti della GASOGEN G3 2S.
Durante il periodo estivo si consiglia di produrre l’a.c.s. con la
caldaia di soccorso, oppure con la caldaia a legna, seguendo
scrupolosamente le indicazioni al cap. 6.11 a pag. 59.

D.H.W. production will have priority and be controlled via the
tank’s loading pump (PR), controlled by a changeover
thermostat. The eventual D.H.W. recirculation pump shall
be connected to the mains independently from the GASOGEN
G3 2S control panel.

During the summer season we recommend that D.H.W. is
produced with the back-up boiler, or with the wood fired boiler,
provided the indications given on paragraph 6.11, page 59,
are strictly
followed.
