Product information
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
• Control the supply of fresh air to the boiler room
• Automatically start/stop via a temperature sensor in the chimney duct
Incorrect use may result in problems with soot, chimney res, etc. which might damage the product.
Please check out this site for advice about the product:
www.exodraft.com

Technical specications
The EBC22 is an automatic control system for single and multiple gas boiler installations and for other
installations in which singularor multiple heat sources are connected to the same chimney. The control may
only be used with Exodraft fans. The EBC22 system consists of an EBC22 controller, which can be positio-
ned anywhere, and a pressure transducer (XTP 150G sensor) which is positioned near the chimney.
The EBC22 control is approved accordingly to the gas directive by Kiwa Gastec.
The EBC22 controller monitors and maintains a specic draught by maintaining a constant pressure. The
pressure in the chimney is measured by the XTP 150G sensor. If the draught falls outside the set point
value the speed of the fan is modulated to achieve the target draught. If it is not possible to maintain the
draught at or above the set point then the controller will automatically disconnect the boiler(s).

Control of... Fitting procedure
Chimney fan • 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 boilers, the probe
must always be positioned after the draft hood.
• Connect the hose from the measuring probe to the negative terminal on the pressure transducer (B”1”).
• When the measuring probe is placed outside it must be mounted in a way that prevents condence or ice to
be formed. EBC22EU02 is delivered with a straight measuring probe. If necessary 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 termi-
nal (B”1”) on the pressure transducer. Run the hose outside the building to a place that is not affected 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 20) set the value to 2 (positive pressure). For operation of the service menu, see
page 19
• Please note that the EBC22 is supplied with only 2 m of hose.
*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.

Outdoor tting of the pressure transducer (XTP)
If there is a risk of adverse effect 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.
