Operating instructions
6.4 - BOILER START-UP
Ensure yourself that all the checks listed in the paragraph 6.3
have been carried out. Open the upper loading door and place
on the main stone, above the central slot, some dry wood, in a
crosswise arrangement.
Use easily inflammable material, avoiding big or squared logs.
Open the lower door.
Using thin paper (newspapers or magazines) light the fire.
Close the door, leaving it slightly ajar.
Wait a few minutes until the fire starts and the some embers
are produced (about 5-10 minutes).
Close the lower door, close the upper door and start the fan
(see point 6.1).
After a few minutes, looking through the sight glass on the
lower door you will see that the flame is beginning to reverse
downwards, at this point add some bigger logs.
Important: during boiler operation the by-pass must always
be perfectly closed.
The wood logs must be of the following size:
a) 50 cm (+ 1 cm, - 4 cm)
for the GASOGEN G3 25/40 2S models
b) 70 cm (+ 1 cm, - 4 cm)
for the GASOGEN G3 50/60 models
c) 100 cm (+ 1 cm, - 4 cm)
fortheGASOGENG3802S
This dimension must be stringently respected.
In order to have a good combustion it is essential that the wood
falls down in a uniformed way.Therefore it is necessary to make
sure that the length of the wood logs introduced, their shape
and the way they are loaded does not prevent the wood from
falling down in a regular way.
The wood logs must be placed in a lengthwise and a horizon-
tal position.
No logs must be placed in an oblique or slanted direction.
SUBSEQUENT WOOD LOADINGS
Before filling the boiler with a new load of wood, use up the
previous one as much as possible.
The boiler can be filled with a new load when the bed of em-
bers is about 5 cm thick.
Slowly open the upper loading door and the inner anti smoke
flap.
The wood logs must have the length specified in the previous
paragraph and they must be placed as previously described.
6.3 - CHECKSTO CARRY OUT BEFORE FIRING
THE BOILER
Before firing the boiler carry out the following checks:
- Check that the On-Off gas valve, positioned upstream of
the boiler, is in the On position (back-up boiler with burner
operating with gas).
- Check that any On-Off valves fitted on the flow and return
pipes for servicing purposes are in the On position.
- Check that any On-Off valves fitted on the cold water inlet
for servicing purposes are in the On position.
- Check that the safety relief valves are connected to the
sewage system.
- Check that the boiler is connected to the electrical supply;
the main switch in position 11 on the control panel must be
illuminated when set to ‘I’.
- Check the heating system pressure, indicated by the pres-
sure gauge (refer to ‘Central heating system pressure’). For
correct operation the pressure should be between 1 and
1,2 bar (with the pump not running).If the pressure falls
below 1 bar, when the system is cold, re-pressurise the
system by regulating the filling valve.
- Check that the by-pass is open when the door is opened
and/or the correct operation via a pushing rod, which can
be found on the right hand side of boiler body, and controls
the microswitch, which in turn consents fan operation.
- Check fan operation with the loading door closed.
Shutting down the boiler
If the boiler is completely shut down, the DHW mode will be
completely disenabled.
To completely shut down the boiler remove the power supply
by opening the contact on the bi-polar switch upstream of the
boiler and setting the switch ‘11’ in the ‘0’ position: the led will
be unlighted.
Place the On/Off gas cock into the Off position (eventual back-
up boiler with gas operating burner) and turn the cold water
supply cock into the Off position.
WARNING!
The heating system can be effectively pro-
tected from frost by using specific antifree-
ze products suitable for multi metal heating
systems.
Do not use anti-frost products designed for
motor vehicles because they could seriou-
sly damage the water sealing gaskets.
