INSTALLATION1.2
BOILER ROOM1.2.1
The boiler must be installed in a fixed loca-
tion, by qualified engineers in compliance
with all the instructions in this manual . The
boiler must be positioned on non combustible
material able to withstand the weight of the
boiler when filled. Furthermore the installa-
tion must comply with current standards and
regulations.
The boiler should be installed as a class B
device( open flued). Purpose made ventila-
tion must be provided and comply with the
following:
– They should have a free section of at least
6 cm2for each 1,163 kW (1000 kcal/h).
The minimum opening section shouldn’t
be smaller than 100 cm2. The section can
also be calculated, using the following
ratio:
Q
S =
100
where “S” is expressed in cm2.
“Q” is expressed in kcal/h
– The opening should be situated on the
lower part of an outer wall, preferably
on the opposite of the one for the exhaust
discharge.
CONNECTION OF THE FLUE1.2.2
A flue should correspond to the following
requirements:
– It should be of waterproof material and
resistant to temperature of the exhaust and
related condensations.
–
It should be of a sufficient mechanical
resistance and a low thermal conductivity.
– It should be ideally be twin walled and
sealed in order to avoid cooling of the
flue.
– It route should be as vertical as is pos-
sible and the terminal part should have a
static aspirator, which assures an efficient
and constant discharge of the combustion
product.
– The flue terminal should be located in a
position free from down draughts, at least
1 metre above the point of exit through
the roof or 600mm above the apex of then
roof- see fig 2a
–
The flue diameter should not be less than
the diameter of the boiler connection; for
flues with square or rectangular sections,
the internal section should be higher than
10% compared to the boiler connection
one.
– The net section of the flue can be obtained
from the following ratio:
P
S = K
√H
S section resulting in cm2
K reduction coefficient:
– 0,045 for wood
– 0,030 for carbon
P boiler capacity in kcal/h
H height of the chimney in meters
measured from the flame axis at the
exhaust of the chimney in the atmos-
phere. For the dimensioning of the
flue you should consider the effec-
tive height of the chimney in meters,
measured from the flame axis at the
top, diminished with:
– 0,50 m for each direction chang-
ing of the connection tube between
boiler and flue;
– 1,00 m for each horizontal devel-
opment meter of the connection
itself.
CONNECTION OF THE PLANT1.2.3
The connections to the boiler must be acces-
sible. Isolation valves MUST NOT be fitted.
Drain points must be included.
Plastic piping should not be used.
CAUTION: It is obligatory to include 3 bar
safety valves on the system not included
in supply.
Plant filling
The heating system should be flushed and
cleaned prior to connection of the boiler.
The final filling should be done slowly to
allow any air to escape.
The cold loading pressure of the plant should

ASSEMBLY OF THE1.2.5
ACCESSORIES
The closing handles for the ports and the
screw with the adjustment knob for the blast
gate damper are supplied separately, to avoid
damaged during the transport.
Both the handles and the screws with knob
are packed in a nylon bag, placed inside the
ash collection basin.
For the assembly of the handles proceed as
following (fig. 4):
–
Take a handle (1), insert it in the opening
of the load port (2) and insert the roller (3)
in the opening of the handle; secure the
handle with split pin (4).
– Carry out the same operation for the han-
dle of the ash box port.
To assemble the screw with the knob, pro-
ceed as follows (fig. 5):
– Remove the screw M8 x 60, which fixes
the air blast damper to the ash box port
and screw the screw with the bakelite
knob (1) on, which is supplied in the pack-
aging.
Place the blind nut with cap (2) at the end
of screw M 10.
– Fix lever M6 to the air blast damper (3)
placing it in a horizontal direction on the
right. The lever has an opening at its end,
where the chainlet of the thermostatic reg-
ulator will be connected.
CASING ASSEMBLY1.2.6
Assemble the casing as shown in figure 6.
The side panes are secured with brackets
to the tie rods that hold the cast sections
together:
– Loosen the second or third nut of each tie
rod.
– Hook the left side (1) on the lower tie rod
and superior of the boiler and adjust the
positposition the nut and locknut to cor-
rectly locate the side panel.
– Fit the RHS (2) panel in the same way as
LHS (1).
– Hook the front upper board (3) on to the

“THERMOMAT RT-C” Regulator
The “Thermomat” regulator is equipped with
a thermosetting resin knob of an adjustment
field from 30 to 100 °C (fig. 7).
Screw the regulator on the 3/4” opening of
the anterior head and orientate the red index
on the upper part.
The lever with the chainlet should be intro-
duced in the regulator holder after having
assembled the instrument holder board and
after having removed the plastic lock.
If the joint is taken out, which fixes the lever
with the chainlet, take care in assembling
it again in the same position. After having
placed the knob at 60°C, block the lever with
the chainlet in a slightly inclined position
downwards, so that the chainlet will be in
axis with the air gate damper.
For the adjustment of the “Thermomat”,
which essentially consists in the determina-
tion of the chainlet length, proceed in the
following way:
– Place the knob at 60°C.
– Switch on the boiler with opened air gate
damper.
– When the water temperature of 60° C is
reached in the boiler, fix the chainlet in
such a way on the lever of the air gate
damper, in order to obtain an opening of
about 1 mm.
– Now the regulator is calibrated and it is
possible to choose the desired operating
temperature by rotating the knob
.
“REGULUS RT2” Regulator
The adjustment field is included between 30
and 90°C (fig. 8). Follow the same instruc-
tions of the “Thermomat” regulator for the
assembly and the activation.

The thermosticker is used to measure the
operating temperature of the burner body.
The temperature measurements provide
information regarding the condition of the
heating system and the need for preven-
tive action or maintenance of the burner
and exhaust ducts.
For example: a high temperature of the
burner may indicate a high ash deposit.
Once the normal operating conditions are
restored, the thermosticker returns to its
normal colour (black).
The burner thermosticker must be checked
on a regular basis, and after any mainte-
nance procedures carried out on the boiler
and/or burner operating with pellets.
The thermosticker indicates an overheat-
ing of the pellet feed tube.
The activation of this thermosticker may
occur if the flue gases flow into the pel-
let tube due to a greater resistance of
the exhaust pipe and/or decrease in the
chimney draft.
In this cases, the flexible connection tube
between the screw feeder and burner body
could be damaged.
Once activated, the thermosticker will not
return to its initial condition. Replace the
thermosticker once the normal operating
conditions are restored.
Viewing of the sticker in the initial condi-
tion: if the active segment is white, the
temperature has not reached the activation
level (104°C).
Viewing of the sticker in the initial con-
dition: if the active segment is dark, the
temperature has exceeded the activation
level (104°C).
