1. Product information
Description
The EBC22 (exodraft Boiler Control) is a specially designed control component for constant pressure regulation of
chimney draft. EBC is specially designed to comply with the Gas Application Directive.
By changing the operating mode, the EBC22 can also:
• Act as a 2-stage speed regulator (see section 3)
• Control the supply of fresh air to the boiler room (see section 4)
• Automatically start/stop via a temperature sensor in the chimney duct
Layout of the instructions
The EBC22 can control an exodraft chimney fan or an exodraft supply air fan.
There are seven sections to the instructions:
• Read section 1. ”Product information”
• Read the section that deals with the required control methods:
Section 2: Pressure-controlled regulation of exodraft fans (factory-set)
Section 3: Two-step speed regulation of exodraft fans
Section 4: Pressure-controlled regulation of exodraft supply air fan
• Read sections 5–7.
Section 2,3, and 4 deal with the following:
Section 2:
• Pressure-controlled regulation of exodraft chimney fans (default).
• The EBC22 ensures and monitors constant pressure in a chimney.
• The EBC22 is designed for use with boiler systems with 1- and 2-stage burners.
• The EBC22 can also be used for boiler systems with modulating burners.
• The control system monitors chimney draft and shuts down the burner in the event of errors (the alarm-
diode on the EBC22 will turn on).
• The control system is intended for both solid fuel boilers, atmospheric gas boilers, condens and forced
draft boilers for oil and gas.
• The EBC22 can control a chimney fan directly or indirectly via a frequency converter.
Section 3:
• 2-stage speed regulation of exodraft chimney fans.
• The EBC22 can be used as a 2-stage speed regulator for exodraft chimney fans.
• The EBC22 monitors chimney draft and shuts down the burner in the event of errors (the alarmdiode on
the EBC22 will turn on).
• The control system is intended for 1- or 2-stage atmospheric gas boilers.
• The EBC22 can control a chimney fan directly or indirectly via a frequency converter.
Section 4:
• Pressure-controlled regulation of exodraft supply air fans.
• The EBC22 can be used to control an exodraft BESB or BESF box fan.
• The EBC22 ensures and monitors constant pressure in a boiler room.
• The control system monitors the pressure in the boiler room and shuts down the burner in the event of
errors (the alarmdiode on the EBC22 will turn on).
• The EBC22 can control a supply air fan directly or indirectly via a frequency converter.

Remark!
• Fit the EBC22 and the pressure transducer (XTP) in the boiler room.
• Fit the measuring probe(A) in the boiler ue or in the manifold. However, for atmospheric boi-
lers, the probe must always be positioned after the draft hood.
• Connect the hose from the measuring probe to the negative terminal on the pressure transdu-
cer (B”1”).
• When the measuring probe is placed outside it must be mounted in a way that prevents con-
dence or ice to be formed. EBC22EU02 is delivered with a straight measuring probe. If neces-
sary the probe delivered with EBC20EU01 can be straigtened and placed so the condens can
run out.
• EBC20 must always be mounted in a way that protects it from the weather (Rain, snow etc.).
Supply air fan • Fit the EBC22 and pressure transducer (XTP) in the boiler room.
• Connect the hose for measuring reference pressure (outdoor atmospheric pressure) to the
negative terminal (B”1”) on the pressure transducer. Run the hose outside the building to a
place that is not aected by wind, rain, etc. If appropriate, t the free end of the hose in a box
as described at the top of the next page.
Note • Special aspects if you require positive pressure* in the chimney/boiler room:
• Connect the hose to the positive terminal on the pressure transducer (B”2”)
• In menu 16 (see page 12) set the value to 2 (positive pressure). For operation of the service
menu, see page 11
• Please note that the EBC22 is supplied with only 2 m of hose.
NB!
*The default setting of the EBC22 is for negative pressure regulation, but local authority
requirements may state that positive pressure must be maintained.
The pressure transducer cannot be mounted inside an air tight enclosure. It uses the
atmospheric pressure as reference pressure.

Make sure to position the pressure transducer the right way up.
Outdoor tting of the pressure transducer (XTP)
A
If there is a risk of adverse eect from strong winds, the hose (A) located inside the
XTP 150G can be removed from the (+) valve.
If the pressure transducer is positioned in a place where insects have access to the
free end, tting a sinter lter is recommended.
Do not blow into the valves on the XTP 150 G

2. Pressure-controlled regulation of the chimney fan
2.1 Use
Area of use
• The EBC22 is designed for use with boiler systems with 1- and 2-stage burners.
• The EBC22 can also be used for boiler systems with modulating burners.
• The EBC22 can also be used for multiple boiler systems
• The control system is intended for:
solid fuel boilers,
atmospheric gas boilers
forced draft boilers for oil and gas
condensing boilers.
• The EBC22 can control a chimney fan directly or indirectly via a frequency converter.
2.2 Method of operation
General function
• The control system monitors chimney draft and disconnects the burner in the event of errors (the alarm-
diode on the EBC22 will turn on).
• When the boiler thermostat demands heat, the chimney fan will start at max. voltage, the burner start is
delayed
• When the EBC22 registers sucient chimney draft, the burner is released.
• The EBC22 maintains the set pressure by regulating the voltage. The pressure is shown in the display.
• In the event of an insucient pressure the burner will be disconnected after 15 seconds.“Insucient pres-
sure”is less than 64% of the set value, corresponding less than 80% ow.
• When the boiler switches o, the chimney fan is also stopped. However, it is possible to set a post-purge
period for the chimney fan (see page 21). Alternatively, the control system can be set up to keep the
chimney fan running continuously (see page 19).
Light emitting diodes and output signals
All inputs and outputs are linked to light emitting diodes for the monitoring and service of the system (1.4.2 Light
emitting diodes and terminal board, page 8 ).
The EBC22 has 0–10V output signals for controlling multiple chimney fans via frequency converters or motor power
relays.
2.3 Electrical connection
This work must be performed by a qualied electrical engineer, in accordance with locally applicable rules and
legislation.
The installation of the supply cable must be carried out in accordance with applicable regulations and
legislation.
The earth terminal ( ) must always be connected.
When connecting pressure transducer (XTP) and frequency converter, screened cable must be used.
Isolation switch
exodraft stresses that according to EU’s Machinery Directive an isolation switch must be set up in the xed
installation.
The isolation switch is not supplied by exodraft. Available as an extra.
