Precipitator function
The draught fan sucks the boiler flue gas through the
precipitator. It is deflected at its bottom and sucked
betweenthe innerwall andtheelectrodeto thefluegas
connection by the electrical field.
Fig. 3-1: Exhaust path
Inside the precipitator is the vertically oriented
"discharge electrode," which is connected to the
high voltage unit. The flue gas is cleaned as it flows
through the electrical field. In the electrical field (up to
30 kV voltage), the discharge electrode "pushes"
the dust particles from the flue gas to the inner wall of
the precipitator. The dust particles accumulate there
and the flue gas is cleaned as a result. Small quantities
of dust will remain adhered to the electrode. Therefore,
it is cleaned in regular intervals.

Deposits on the inner walls are removed by a sliding
rake which moves up and down. The sliding rake
operates at the same time as the de-ashing of the
boiler. The ash is transported on the bottom to the ash
box by an ash screw.

Installation Connect the precipitator with the boiler
11
If a flue gas recirculation is installed, the flue
ducts must also be removed from the flue gas re-
circulation.
To close the opening, mount the cover plate with the
seal supplied on the boiler.
5.2 Connect the precipitator with the
boiler
Place the precipitator
To place a size 1 or 2 precipitator (20 - 90 kW), mount
the carrying tube on both sides. In the case of a size 3
precipitator (110 - 130 kW), carefully lift with a
pallet jack.
Place the precipitator next to the boiler. The supplied
piping is suitable for placing the precipitator on the
opposite side of the fuel discharge. The required
clearances are found under 2 "Technical data".
If the precipitator is mounted to the left of the
boiler, the de-ashing drive motor must be rotated.
This is because 20-50 kW boilers have drive motors
which protrude over the panels.
Fig. 5-1: Rotate the drive
Inspect the horizontal alignment of the precipita-
tor and shim if necessary. Compensating shims
are included in the delivery scope. To inspect, remove
the cover on the top as well as the maintenance cover.
The electrode within is now visible. The

12 www.eta.co.at

horizontal alignment is important, because equal
clearance of the electrode to the inner walls is required
on all sides.
Fig. 5-2: Check alignment
Fig. 5-3: Electrode
The precipitator can also be placed in another
location in exceptional cases. Contact us about
optimising the installation of the precipitator in this
regard. The piping between the boiler and precipitator
as well as the flue gas recirculation piping must be set
up separately.
If the boiler is placed on sound insulation mats,
the precipitator must also be placed on
sound insulation mats.
Install the draught fan and flue gas connection
Remove the panel from the top of the precipitator.
Evenly mount the draught fan with hexagonal screws
onto the precipitator.
A longer connection line for the draught fan
already protrudes from the precipitator. Plug it
into the draught fan and guide the other end over the
cable duct to the boiler. Remove the existing line
located there and clamp in the longer connection line
in its place.

Installation Connect the precipitator with the boiler
13
Fasten the flue gas connection with a new seal to the
precipitator.
Install piping for the flue gas
Install the flue pipe with hexagonal screws and a new

Also attach the CAN-Bus to the circuit board [HA-C], or
if it is occupied, to another open CAN-Bus terminal.
A terminal resistor (yellow jumper) must be set at
the end of the CAN-Bus . If both CAN-Bus
terminals are allocated, the terminal resistor must be
removed on this circuit board.
In the example listed above, the terminal resistor must
be removed from the circuit board [HA-C] at [X49].
Check the node numbers if the circuit boards are
the same design.
If multiple circuit boards of the same design (e.g.: 2x
EM-C) are connected to one another via CAN-bus, the
circuit boards of the same design must have serial
node numbers. In this way they are recognized in
CAN-bus and can be configured.
