Operating instructions
For correct air adjustment it will be necessary to observe the
flame through the sight glass, placed on the lower door. The
flame will have to occupy about two thirds of the combustion
chamber, and will have to quietly lick the lower cradle, without
moving the ash too much and without making any noise.
The flame must be an orange-pink-white colour, not too
transparent and with the centre part veering to light blue.
The GASOGEN G3 25/40 and 50 2S models: t
o bring the
flame to optimal conditions,
it will therefore be necessary
to
regulate the primary air
by screwing or unscrewing the screw
(pos. P); the same operation must be carried out for the
secondary air with the screws placed in position S.
The GASOGEN G3 65 2S and GASOGEN G3 80 2S models:
t
o bring the flame to optimal conditions,
it will therefore be
necessary
to regulate the primary air
by screwing or
unscrewing the metal ring nut (pos. 1) on the air distributor;
the same operation must be carried out for the secondary air
on the second air distributor.
Example n.1
Thick, wet wood logs = difficult combustion
S - Very closed (try to get the maximum dimension of the flame,
but not a reddish colour).
P - Reasonably open in order to obtain a sufficient gasification.
Example n. 2
Very inflammable wood logs
S - Completely open.
P - Slightly closed to reduce the gasification, but sufficiently
open to evacuate the ash that can close the combustion head.
GENERAL SUGGESTIONS
Better performances are obtained after two - three days of ope-
ration. The refractory cement, in fact, needs to be baked and
the tar has to cover the upper part of the fire box.
-
The flame has to have good dimensions and reasonably
fill-up the combustion chamber.
- The
flame
must not be
too red
(lack of secondary air S).
- The
flame
must not be
too blue
(excess of secondary air S).
- The
flame
must not be
too noisy
(excess of primary air P).
- The
flame
must not be
too small
(lack of primary air P).
- If
the ash does not falls down properly
- increase the pri-
mary air P.
- If
too much ash falls down -
reduce the primary air P.
6.6 - CHECKS TO CARRY OUT AFTER THE
FIRST START-UP
SOUNDNESS CHECK
During the first start-up check the soundness of the seals of
the flue circuit and the chimney connection.
If you notice smoke leakages inform the installer or the After
Sale Service. If you notice air
suctions through the door’s seals, close the door handle with
greater strength.
Check the normal operation of the working thermostat Te (32)
at full until it arrests the fan.
Check there are no water leaks from the water connections.
After the first start-up, with the boiler OFF, open the lower door
and inspect the internal walls and the door insulation which
has to be of a white colour, indication of a correct air adjust-
ment.
On the contrary, if the walls are blackened, it means that the
secondary air is not working properly (paragraph 6.5).
- If
the chimney smokes -
open the secondary air S comple-
tely.
- If
the chimney continues smoking
- adjust the secondary
air S to maximum and reduce the primary air. P.
AIR ADJUSTMENT FAULTS
1) If
the primary air is excessive
a lot of ash and small pie-
ces of coal will fall through the slot into the combustion cham-
ber. The flame is too fast, dry, a cold colour and makes a noi-
se.
The boiler is consuming a lot of wood and the door’s refractory
insulation is white.
2) If
the primary air is insufficient
the flame will be slow,
indecisive, influenced by air currents and by the chimney drau-
ght, very small, incapable of touching the lower cradle, with
low ash production and the door’s refractory insulation will be
of a dark colour.
3) If
the secondary air is excessive
the flame will be small, a
blueish colour and very transparent.
4) If
the secondary air is insufficient
the flame will be big, it
will touch the lower cradle, it will completely fill the combustion
chamber and, above all, it will be a red colour and not transpa-
rent
