c needs. In this case and in particular if
the diameter and length of the ducts have
been changed or if the number of bends
has been modifi ed, air output may vary.
Consequently it is very important to check
and regulate air output when any modifi
cation is made to air heads or air ducts. In
all circumstances you must ensure that:
►
The fan motor does not absorb more
current than the maximum permitted limit;
►
The volume of air fl ow corresponds to
the recommended level.
WARNING !!!: Only attach ducts
with allowable constant working
temperature of at least 150ºC (al
-
lowable temporary working temp.
at least 180ºC) within the first 2
meters away from the heater, and
85ºC further away on the entire
length of the circuit. We recom
-
mend to use MASTER brand ducts.
WARNING !!!: After connecting
distribution ducts, please consi
-
der their proper arrangement. To
minimize air flow obstruction and
device load, arrange the air distri
-
bution ducts so that the number
of bends is minimized and limit
the duct bending angle to at least
90° at all times. Moreover, the ini
-
tial 2 meters of the duct should
be without bends (fig. 4).
CONNECTION TO FLUE (fig. 5, 6, 7)
Thermal effi ciency and proper functioning
are directly related to correct draft in the
chimney.
►
Make sure distance between heater
and chimney is as short as possible, do
not create ciosed angles or chimney sec-
tion reductions.
►
If the heater is not connected to an out
-
side chimney, it must be equipped with a
vertical steel fl ue and a draft regulator.

4. RUNNING THE HEATER
TO START THE HEATER
►
Set switch (2) on position “O”, connect
heater to mains (see model plate for elec
-
trical specifi cations).
►
If the heater is to be run under manual
control, set switch (2) on position
the
burner will start and after a short time of
combustion chamber preheating the main
ventilator will start.
►
If the heater is to be run under automa
-
tic control, set desired value on selected
control, set switch (2) on position
the
heater will now start and stop automati
-
cally.
►
If after these operations the heater
does not run properly, revert to chapter
“OBSERVED FAULTS, POSSIBLE CAU
-
SE REMEDIES” and fi nd out reason of
malfunction.
TO STOP HEATER
►
In manual mode, set switch (2) on po
-
sition “O” or turn off control in automatic
mode.
►
Burner will stop and main ventilator will
stop later when combustion chamber has
cooled off.
WARNING !!!: Never pull plug to
stop heater. Never pull plug befo
-
re heater has stopped by it self.
VENTILATION
To run your heater as a ventilator only, set
switch (2) on position
.
