To bring the ﬂ ame to optimum conditions you should

then adjust the primary air by turning the knob (pos.

P). Do the same for the secondary air (pos. S).

Example n.1

Thick damp wood that is difﬁ cult for combustion

S - Very closed (try to get the maximum dimension of

the ﬂ ame, but not of a reddish colour).

P - Reasonably open in order to obtain a sufﬁ cient

gasiﬁ cation.

Example n. 2

Very inﬂ ammable wood logs

S - Completely open.

P - Slightly closed in order to keep gasiﬁ cation reduced,

but sufﬁ ciently open to evacuate the ash that can close

the combustion head.

GENERAL ADVICE

- Better performance will be achieved after two or

three days of running. Refractory material must be

cooked and the tar must encrust the upper walls of

the wood storage compartment.

- The ﬂ ame should have a good size and fairly ﬁ ll the

combustion chamber.

- The ﬂ ame should not be too red (lack of secondary

air S).

- The flame should not be too blue (excess of

secondary air S).

- The ﬂ ame should not be too noisy (excess of primary

air P).

- The ﬂ ame should not be too small (lack of primary

air P).

- If the ashes do not go down well, increase the primary

air (P).

- If too many ashes fall, decrease the primary air (P).

- If the chimney is smoky, open the secondary air (S)

all the way.

- If smoke continues to escape, open secondary air (S)

to a maximum, closing the primary air (P) partially as

well.

6.8 CHECKS TO BE CARRIED OUT AFTER

COMMISSIONING

CHECKING SEALS

During the initial start-up, check the tightness of the

smoke circuit and the connection to the chimney. If

there is any noticeable smoke leakage, alert the installer

and/or our After-Sales Service. If there is any noticeable

aspiration of air through the door seals, tighten the

handle with greater force.

Make sure the working thermostat is in good running

order Te (32) at full power until it stops the fan.

Check for leaks from pipe connections.

AIR ADJUSTMENT FAULTS

1) If the primary air is excessive, a lot of ash and small

pieces of embers will fall. The ﬂ ame is too fast, dry, has

a cold colour and makes noise.

The boiler is consuming a lot of wood and the door's

insulation is white.

2) If the primary air is insufﬁ cient, the ﬂ ame will be slow,

hesitant, affected by air currents and by the chimney

draught, very small, incapable of touching the lower

cradle, with low ash production and the door's refractory

insulation will be dark coloured.

3) If the secondary air is excessive. the ﬂ ame will be

small, of a bluish colour and very transparent.

4) If the secondary air is insufﬁ cient. the ﬂ ame will be

big, it will touch the lower cradle, it will completely ﬁ ll

the combustion chamber and, above all, it will be of a

red colour and not transparent.

After the initial start, with the boiler off, open the lower

door and inspect the internal walls and insulation of

the door: they should be of a light colour, indicative of

a proper air adjustment.

Otherwise, if the walls are blackened, it means the

secondary air is not adjusted properly (par. 6.7).
