Instructions for the User
Since for a good combustion it is essential that there is an
uniform falling down of the firewood, it is necessary to make
sure that the length of the introduced wood logs, their form
and the way of loading don’t prevent the regular descent of
the fuel.
The wood logs must be placed longitudinally and
horizontally. No log has to be placed slanting or athwart.
SUBSEQUENT LOADINGS
Before making a new loading of wood, consume, as much as
possible, the previous one.
The new loading will be done when the bed of embers, on the
grate, will be reduced to a thickness of about 5 cm.
Open slowly the upper loading door.
Use only wood logs having a length as stated in the previous
paragraph.
Place the new loading of wood as above described.
USEFUL SUGGESTIONS AND LOADING ERRORS
- Too long logs do not fall down regularly and can cause
“bridges”.
- Too short logs cause not regular air passages, with
consequent reduction of output and efficiency.
- In case the quality of the wood causes “bridges” it could be
necessary to cut the wood logs in two parts, as stated in the
paragraph FIRST LOADING.
- Open the upper door always slowly, in order to avoid
blowbacks and smoke formations.

COMBUSTION AIR ADJUSTMENT
ADJUSTMENT OF PRIMARY AND SECONDARY AIR
The boiler FOKOLUS is equipped with primary
air (pos 5, fig. 1) and secondary air adjustment
(pos 4,Fig. 1). The primary air adjustment is
done automatically through the thermostatic
valve; the secondary air, however, done through
the port located on the upper loading door, must
be done by the user, tightening or loosening the
adjustment screw.
At the first start it is necessary to adjust the primary and the
secondary air and bearing in mind that the primary air
determines the boiler output, and therefore the amount of
wood that is burned, and the secondary air completes the
combustion.
The optimal setting of the FOKOLUS operation is obtained
when boiler and chimney are in “warm conditions”.
GENERAL SUGGESTIONS
- Best performances are obtained after two/three days of ope-
ration. Refractory material must be cooked.
- The flame should have a good size and fairly fill the firebox.
- The flame should not be too red (insufficient secondary
air S).
- If the chimney is smoking too much (open all the secondary
air S).
- If it continues smoking, give maximum of secondary air.
Example No. 1
Big wet wood logs of difficult combustion:
SECONDARY AIR: Very closed (try to get the maximum size
of the flame, but not of the red color).
Example No. 2
Highly flammable wood logs
SECONDARY AIR: - Completely open.

CHECKS TO BE CARRIED OUT AFTER
THE FIRST START
CHECKING OF THE 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
leaks alert the installer and / or the After Sale
Service.
If there is any noticeable air suction through the door seals,
tighten the handle with greater force.
Check for water leaks from pipe connections.
