IGNITION
Make sure all the controls listed in 6.5 have been
carried out.
For the GASOGEN G3 25 2S, GASOGEN G3 40 2S and
GASOGEN G3 50 2S models:
Screw down completely the primary air’s ( P ) adjustment screw
Screw down completely the secondary air’s ( S ) adjustment
screws until you “detect” the resistance of the spring pushing
the closing discs.
Now, “
unscrew ” about 10 turns the primary
Air’s ( P ) screw and 4 turns the secondary air’s ( S ) screws.
For the GASOGEN G3 65 2S and GASOGEN G3 80 2S
models:
The initial position of the ring nuts
(pos. 1, fig. 48) which
control the opening or closing of the primary and secondary
air,
has to be about in the middle of the threaded rod.
The primary air (P) is blown through the upper fan, whilst the
secondary air (S) is blown through the lower one.
At this point,
“screw” or “unscrew” the ring nuts (pos. 1, fig.
48) on the threaded rod until you have an optimal air regulation,
by observing the colour of the flame in the combustion chamber;
keep in mind that by rotating the ring nuts in a clockwise
direction (that is upwards) you will have an increase of the
emission of the air (primary or secondary), vice versa, a
reduction.
Open the upper loading door and place above the main stone’s
central slot, some thin and dry pieces of wood, in a crosswise
position.
Prefer easily inflammable wood, avoiding big pieces and square
shaped pieces.
Open the lower combustion chamber door.
Using sheets of thin paper (newspapers or similar) light the
wood previously placed inside.
Leave the upper door ajar.
Wait several minutes until the fire starts and produces some
embers (about 5 - 10 minutes).
Close the lower door first and then the upper door: at this
moment the fan is automatically switched ON (point 6.1).
After some minutes, if you look through the sight glass, it is
possible to see that the flame
starts reversing downwards, so you can add some other larger
wood pieces.
Important: during boiler operation the bypass must be
always perfectly closed.
The wood has to be of the following length, according to the
boiler model:
a) 50 cm (+ 1 cm, - 4cm) for the GASOGEN G3 25 2S and
GASOGEN G3 40 2S models
b) 70 cm (+ 1 cm, - 4 cm) for the GASOGEN G3 50 2S and
GASOGEN G3 65 2S models
c) 100 cm (+ 1 cm, - 4 cm) for the GASOGEN G3 80 2S model
These dimensions must be absolutely 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

C = Ventilation control box
S= Secondary air adjusting screws
P= Primary air adjusting screw
P1 = Primary air passages
S1= Secondary air passages
and the way they are loaded does not prevent the wood from
falling down in a regular way.
The wood logs must be placed lengthwise and in a horizontal
direction.
No log must be placed in an oblique or slanted direction.
SUBSEQUENT WOOD LOADINGS
Before carrying out a new loading of wood use up the previous
load as much as possible.
The new load can be made when the bed of embers 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.
USEFUL SUGGESTIONS and LOADING ERRORS TO BE
AVOIDED
- Logs too long do not fall down properly and can cause
obstructions.
- Logs too short cause irregular air passages, with consequent
reduction in output and efficiency.
- In case the quality of the wood causes “obstructions” it could
become necessary to cut the wood logs in two parts, as shown
in fig. 49, in order that the total length “L” is as indicated in the
previous paragraph.
- Always open the upper door slowly in order to avoid blowbacks
and smoke formation.
- During normal boiler operation it is absolutely forbidden to
open the lower combustion door.
