Product description
The ESP-25 is an electrostatic precipitator (particle lter) for pellet boilers for inline installation in indoor
chimney constructions and is placed directly after the pellet boiler. The ESP-25 is designed to reduce the
level of particles from pellet boilers.
The ESP-25 is intended for non-condensing pellet boilers with a maximum heating output of no more than
25 kW and can only be used on chimney constructions with negative pressure.
The ESP-25 is supplied on a standard Ø150 uninsulated ue, with a 5-metre-long supply cable with strip-
ped conductors for plug installation.
If the pellet boiler is not adjusted for proper combustion, it may cause problems with soot, chimney res,
etc., which may damage the product. Please follow the instructions from the manufacturer of the pellet
boiler.
Scope of supply

Functionality of the electrostatic precipitator
ESP-25 is an electrostatic precipitator that reduces the number of ne and ultra-ne particles in a ue gas
stream by creating an electrostatic eld between the charging and collecting electrodes.
The electrostatic eld is generated by the charging electrode which is connected to a high voltage controller
which ionises the surrounding gas, consequently charging the particles and creating an electrostatic eld
strong enough to push the charged particles towards the ue (collecting electrode). The ue gas particles
are captured and retained in the electrostatic eld and can be removed when the lter is cleaned.

Automatic on/off
It is possible to connect the ESP-25 to the pellet boiler so that it receives an automatic start/stop signal and

off with the boiler. See Electrical installation.

Precautions
Be aware that the ESP-25
• must be mounted with the approved Exodraft accessories.
• must be accessible for service and maintenance from the boiler room.
• must be installed at least 500 mm from ammable materials.
• must be installed at least 500 mm from the boiler due to possible thermal exposure.
• must only be installed on a chinmey construction that can support it’s weight.
• must only be installed on a chinmey construction that is not leaking.
Other recommendations
• it is recommended that the chimney is swept and any deposits and blockages are removed before
installation.
• it is recommended that a smoke alarm is always installed together with a pellet-red system.

Mechanical installation
Exodraft products must always be installed by properly qualied personnel and according to the
manufacturer’s instructions. Installation of the ESP-25 must be done in consultation with your chimney
sweeper.
As the ESP-25 is installed as part of a pellet boiler system, the user must ensure that the design meets the
relevant requirements of the country/region.
Positioning of the ESP-25
• Must be installed in the pellet boiler system’s existing chimney system.
• Must be installed in steel chimney systems. See diameter constraints under System type.
• Must be installed in chimney systems with an approved adapter (if an adapter is necessary).
• Must be accessible for service and maintenance by standing on the ground or using a ladder.
• Must be positioned so that the viewing angle of the LED is visible from the operating side of the pellet
boiler.
• Must only be mounted in a vertical position. DO NOT MOUNT HORIZONTALLY.

Before installation in a chimney construction
Before installation of the ESP-25, it must be ensured that the electrode is in the correct position. If the elec-
trode is out of its correct position, the electrostatic precipitator will not function correctly.
Aligning the electrode
Check the position of the electrode before installing the ESP-25. Check that the electrode is positioned in
the centre of the ue. If the electrode is not correctly adjusted, try to readjust it by removing the top cover (6
screws, tool - TX20), then loosen the set screw (tool - 3 mm Allen key), adjust the electrode and retighten
the set screw.
ATTENTION! The power supply must always be switched off when adjusting the electrode. Touching the electrode while
the power is on can be fatal.

Brush stop
The supplied brush stop must be used in installations where the chimney sweeper cleans the chimney from
the roof and does not have access to the ESP-25 in the boiler room. The brush stop can be installed from
the top. The brush stop is intended to prevent the chimney sweeper from impacting the electrode when
cleaning the chimney from the roof.
The chimney sweeper must always be made aware that the chimney is tted with an ESP-25! Please refer
to sections Attach the warning signs and Chimney sweeping.
Installations where the chimney is always cleaned from below from the boiler room, the brush stop does
not need to be installed. Please refer to section Chimney sweeping.

Installation in a chimney construction
The illustrations below shows the recommended installation. Depending on the chimney system (manufac-
turer), adapters may be required between the ESP-25 and the ue pipes.
If installed on a boiler with rear ue outlet, it is recommended to install a Tee piece with a soot cap to
remove dust either from the boiler or particles/dust collected by the ESP-25 and later deposited after the
cleaning process.
If installed on a boiler with an upward ue outlet, it is recommended to install a ue pipe section with
a cleaning door to remove particles/dust collected by the ESP-25 and later deposited after the cleaning
process.
It is recommended that the viewing angle of the ESP-25 LED is visible from the operating side of the pellet
boiler.

Electrical installation
The electrical installation should only be carried out by qualied personnel in compliance with applicable
laws.
General information
• The electrical installation must be carried out in compliance with applicable laws.
• The ESP-25 must have (PE) ground connection. Power supply needed: 230 V AC / 1.0 A.
Power connection
The ESP-25 is delivered with stripped conductors. A plug with (PE) ground connection needs to be installed
on the ESP-25. The plug must match the local requirements for electrical installations.
Exodraft recommend that a 2 pole isolation switch, is to be tted to the cable.
To avoid unnecessary power consumption, remember to turn off the ESP-25 when the pellet boiler is
off.
Power connection by automatic on/off - option 1
ESP-25 can be connected to the pellet boilers main board and be congured to start and stop with the pel-
let boiler if it has an available 230 V output. The 5 metre long cable with stripped conductors must then be
routed to the pellet boilers outlet according to the electrical diagram.
ATTENTION! Always disconnect the power supply before working on ESP-25 and make sure that it cannot be
reconnected accidentally. Always check that the installed isolation switch is set to off and/or the pellet boiler
is turned off.

Power connection by automatic on/off - option 2
ESP-25 can be connected to the boiler through a relay setup (control box start / stop). In this way, ESP-25
can be connected to all available 24-230V outputs on the pellet boiler.
• Prepare a control box to contain the relay system. E.g. use a suitable plastic enclosure and use cables
glands for strain relief of cables.
• Connect the 5 metre long supply cable from the ESP-25 to an external power supply cable. Make the
connection with terminal strip/block inside the Control Box.
• Connect a 2-wire cable from one of the pellet boiler’s 24-230V outputs to a 24-230V relay.
• Replace the M12 blind plug mounted in the Controllers output F with a M12 cable gland. Replace the
M12 blind plug mounted at the bottom of the ESP-25 with a M12 cable gland.
• Connect a 2-wire cable from the 24-230V relay to the controllers 6-pole terminal block. Route the
cable through the cable glands.
• Move the jumper on the controllers mainboard.
