Once proper draft is achieved thecontrol will release the gas-valve and allow the flow of fuel. When turning the switch off, the control willshut down the flow of fuel, which turns off the fireplace. In case of insufficient draft or mechanical/electricalfailure, the Proven Draft Switch and the control will shut off the gas valve and the flow of fuel.EBC 5FANMOTORPOWER SUPPLY120/1/60COML24VACNTRANSFORMER120/24VACW/BlueEXHAUSTOW/YellowBrownBlackWhiteBlackRedCapacitorRedWhiteBlackGreenJunction Box10-30vWALL SWITCHCOMTRHOTTH24V GAS VALVEN L1POWER SUPPLY1 x 120 V AC10

3901863 12.055.1 General5. Startup and ConfigurationThe purpose of this control is to ensure safe venting for a single appliance where modulation is not required. Thisis accomplished by starting a chimney fan/power venter when the appliance calls for heat and stopping the fanwhen the heat demand has been satisfied.5.2 Sequence of OperationStartSequenceOperatingSequenceShutdownSequence1. The appliance activates the EBC 5 Relay to initiate the call for heat.2. The EBC 5 control sets fan output to 100% for a 15 seconds pre-purge cycle.3. The Proven Draft Switch closes when adequate draft has been achieved.4. The EBC 5 control releases the appliance for operation by activating the EBC 5 Relay.1. The control adjusts fan output to the percentage set by DIP switches 3-8.2. If the Proven Draft Switch opens, fan output is set to 100% and a 15 seconds timing cycle starts.3. If the Proven Draft Switch does not close within 15 seconds, the fan out turns off and an alarm condition exist.4. If the Proven Draft Switch closes, the control automatically resumes step 1.1. The call for heat signal from the appliance is turned off.2. Fan output continues at the pre-set speed for 0, 30, 60 or 90 seconds as set by Post-Purge DIP switches 1 and 2.3. Fan output is set to zero5.3 Adjusting Fan SpeedThe fan speed can be adjusted by setting DIP switches inside the control according to this table:ON1 2 3 4 5 6 7 8DIP Switches (shown inOFF position)Fan Speed OutputSpeed DIP3 DIP4 DIP5 DIP6 DIP7 DIP830% OFF OFF OFF OFF OFF OFF42% ON OFF OFF OFF OFF OFF54% ON ON OFF OFF OFF OFF65% ON ON ON OFF OFF OFF77% ON ON ON ON OFF OFF89% ON ON ON ON ON OFF100% ON ON ON ON ON ON5.4 Setting Post-Purge DelayThe Post-Purge delay can be adjusted by setting the DIP switches inside the control according to this table:Post-Purge DelayTime DIP1 DIP20 sec OFF OFF30 sec ON OFF60 sec OFF ON90 sec ON ON11

Maintenance and TroubleshootingObservation Problem SolutionHeating appliance/fireplace cycle on andoff- Fan speedcontrol is settoo low.- Fan speedcontrol is bad- Increase fan speed setting- Replace fan speed control.Fan is ‘hunting’(increasing speed andthen decreasing speedconstantly)Heating appliance/fireplace will not comeonHeating appliance/fireplace will not shutoff- Fan speedcontrol is settoo low.- Proven draftswitch setting istoo high- Fan is notworking- No power tothe EBC 5- Provendraft switch isnot properlyconnected tothe chimney.- Relay orproven draftswitch is bad- Proven draftswitch is notwired correct- EBC 5 is notwired correctly- Relay orproven draftswitch is bad- Increase fan speed setting.- Lower the pressure setting on the proven draft switch- Check the fan and if necessary, repair or replace. Check wiring, it may not be receivingstart command.- Connect power to EBC 5- Make sure the probe is properly inserted into the stack, so the tip of the probe is flushwith the inside of the chimney. If serving a fireplace the probe should be 3 to 4 below thefan. If serving a heating appliance it should be 2-4 feet away from appliance outlet.- Replace relay or switch- Check wiring and correct.- Check wiring and correct.- Replace relayEXHAUSTO Inc.1200 Northmeadow Pkwy.Suite 180Roswell, GA 30076P: 770.587.3238F: 770.587.4731T: 800.255.2923info@exhausto.comus.exhausto.com
