1. Product Information
1.1 Function
Use The EXHAUSTO EBC 10-P or 10-E Fan Control is for use with single heating appliances where modulation
is not required. It is designed to monitor and create proper draft and pressure in a chimney system. The
control may be used with EXHAUSTO fan models RS, RSV, GSV, RSIB and RSIF.
 Typicalusesincludecontrollingdraftforagas-redwaterheater,boiler,furnace,replace,stove,BBQor
pizza oven.
Function The EBC 10-P integrates a fan speed control and an internal Proven Draft Switch (PDS) with a pressure
probe. The EBC 10-E integrates a fan speed control only. This model must be connected to an external
EXHAUSTO PDS-1 to provide the same functions as the EBC 10-P.
The user can set the control to run the exhaust fan continuously. When used with a 3-phase exhaust fan a
Variable Frequency Drive (VFD) is required. It will allow the user to manually adjust the speed of the
fan while it is in use.
The control can also be interlocked with the appliance to make the pre-purge and post-purge functions
available. The pre-purge function prevents the operation of a heating appliance until the set draft point has
been reached. The post-purge function allows the fan to operate for 12 minutes after the appliance
 hasbeenshutdown.Thisallowsanyexcessuegasesorproductsofcombustiontoevacuate 
the chimney system.
When the EBC 10 is connected to an internal or external PDS, the control provides a safety function that
prevents an appliance from operating in the event of an electrical or mechanical failure. The PDS is
 suppliedwithapressureprobethatconstantlysensesthedraftinthechimney.Ifinsufcientdraftexists,
 thecontrolwillgraduallyincreasethefanspeeduntilthedraft-setpointissatised.Ifthispointisnot
 satisedafter12seconds,thecontrolwillshutdowntheappliance.Thereisanautomaticresetonthe 
control to prevent nuissance lockouts or the need for manual reset.
Construction The housing is made of NEMA 1 rated polycarbonate.
Code Compliance System installation must conform to the requirements of the authority having jurisdiction. When required by
the authority having jurisdiction, the installation must also conform to the NFPA31, NFPA54 or NFPA211.
All electrical wiring must be in accordance with the requirements of the authority having jurisdiction or, in
absence of such requirements, with the National Electric Code, NFPA 70.
Listings The circuit board and other components in the EXHAUSTO EBC 10 are ETL or UL listed.

3. Mechanical Installation
3.1 Location
The EBC 10 Control Unit must be installed indoors in the vertical position, preferably in the room where the
appliance is located. As shown in the diagram below, the control will be wired directly to a 120/1/60 VAC power
supply. The control will also be wired into the appliance and the junction box provided with the fan. For detailed
wiring information, see Chapter 4.
3.2MountingtheControlUnit
The EBC 10 control may be mounted directly to a wall. To mount, remove the cover and locate the (4) mounting
holes. Using the hole-pattern shown below, mount the control using the appropriate sized hardware. Once it
is attached, the unit may be wired in accordance with Chapter 4 and the cover may be replaced.

3.3 Connection of the Proven Draft Switch
A Proven Draft Switch (PDS) must be used with the EBC 10 control as a system safety device. The PDS
  monitorsthepressureinsidethestackandsignalsthecontroltoshutdowntheapplianceifinsufcientdraft
exists. A stack probe senses the pressure read by the PDS and is connected via silicone tubing.
For model EBC 10-P, connect the silicone tubing through the port located at the bottom of the control
enclosure as shown in Fig. 4 (this port is connected to the internal PDS). The other end should be attached
to the stack probe.
For model EBC 10-E, an external PDS-1 must be wired to terminals 16, 17 and 18 of the control. The
silicone tubing will run from the PDS-1 to the pressure probe. For wiring detail, see Chapter 4.
The standard tube length is 6 feet. The distance can be extended up to 25 feet by using 1/4” rigid plastic or
copper tubing as temperature allows (not supplied).
3.4 Installation of the Stack Probe
The probe must be installed between the appliance and the exhaust fan.
  Locatetheprobeatleastadistancethree(3)ventdiametersawayfromanyelbowortee.Forreplace 
installations, the stack probe should be installed as close to the exhaust fan as possible. If the probe is
installed on a horizontal pipe, it must be installed above the centerline of the pipe. See Fig. 5.
To produce an accurate pressure reading, theprobeshouldbeinstalledasclosetoushaspossiblewith
  theinnerwallofthestack.Ifdoublewalledstackisused,theprobeshouldbeushwiththeinnermostwall.

3.5AdjustingtheFanSpeed
A potentiometer is located on the main control board of the EBC 10. This is used to manually increase or
decrease the speed of the fan. To increase the fan speed, rotate the potentiometer clockwise. Alternately,
rotating the potentiometer counterclockwise will decrease the fan speed.

4.5WiringwithaVariableFrequencyDrive
The EBC 10 Control can be installed with a Variable Frequency Drive (VFD). This allows the fan speed to
be manually adjusted by the user depending on draft conditions. When using a VFD, the fan is NOT
connected directly to the control. The VFD is connected to terminals 25 and 26. The wires running from
the fan junction box is connected into the VFD via terminals W, V and U as shown in the Fig. 11.

  5.StartupandConguration
5.1 General
Dip switches are located on the control board. Verify settings using the table below.
5.2SequenceofOperation
1. The appliance energizes EBC 10 inputs at terminals 5 and 6 to initiate the call for heat.
2. The EBC 10 control sets fan output to 100%.
3. The Proven Draft Switch closes when adequate draft is achieved and EBC 10 slows fan to set speed.
4. The EBC 10 control releases the appliance for operation by closing dry contact between terminals 14 and 15.
1. The control adjusts fan output to the percentage set by the control board Potentiometer.
2. If the Proven Draft Switch opens, fan output is set to 100% and a 12 sec. timing cycle starts.
3. If the Proven Draft Switch has not been made within 12 sec., the appliance output turns off and an alarm
condition exists.
4. If the Proven Draft Switch closes, the control automatically resumes normal operation at step 3 of start sequence.
1. The call for heat signal from the appliance is turned off.
2. Fan output continues at pre-set speed for 12 minutes if post purge cycle is selected at dip switch.
3. Fan output is set to zero
5.3SettingtheOperatingPressure
The operating pressure of the EBC 10 Control should be set by the user prior to using the system. This pressure
 shouldbesetwithintherangetheappliancemanufacturerhasspeciedintheappliancemanual.Theusermust 
use a manometer or other device to read the pressure inside the stack.
 Fordrafthoodsordivertersandreplaces,astandardsmoke/ametestshouldbeperformedbeforenormal
 operation(speciedinappliancemanual).
