1. SYSTEM & COMPONENT DESCRIPTION
1.1 General
TheENERVEXMultipleFireplaceExhaustSystemisamodulatingexhaustsystemdesignedspecically 
forthecommonventingandexhaustofmultipleISOKERNgas-redreplacesinresidential,multi-story 
buildings. The system includes an EBC 30 Control, one or more RSV fans, an ABB Variable Frequency Drive
(ifapplicable),anADMautomateddamper,anISOKERNIBVmodelreplaceandanISOFLAMESgaslogset.
EachreplaceueconnectstoacommonverticalventthathasaRSVfanattheterminationpoint.TheEBC30
modulates the fan speed to maintain the pre-set, negative pressure in the vent.
1.2 Component Description
a. EBC 30 Constant Pressure Regulator
The EBC 30 Constant Pressure Regulator controls the system to maintain the required pressure
set-point. The control regulates draft pressures by modulating the fan speed based on readings
from a pressure transducer (XTP2).
b. RSV Chimney Fan
Thereplacesystemisventedthroughoneormore RSV model chimney fans. If the fan operates
on 3-phase voltage, a Variable Frequency Drive (VFD) is used to modulate the fan speed. The
VFD connects in between the fan junction box and EBC 30. A single phase fan connects directly to
the add-on triac board inside the EBC 30 control box.
c. XTP2 Sensor
The XTP2 Sensor is an external pressure transducer that monitors pressure in the vertical common
vent. The transducer converts measured pressure into a corresponding voltage. This voltage is
relayed to the control to modulate the damper position and/or fan speed, thus regulating the
pressure at the set point.
d. ADM
The ADM is a motorized damper controled by a two-postition (open/close) actuator. The damper
connects to standard B-vent. If necessary, the stroke length of the actuator easily adjusts to open
less than 90o.
The actuator includes an auxiliary switch that ties into the burner’s thermal limit circuit, which
operates on mili-volts. When the actuator moves to its open position, the auxiliary switch
closes. When the pilot heats up the thermocouple, the limit circuit fully closes and releases the gas
    valve.Thecircuitpreventsthereplacefromoperatingwhenthedamperisclosed.Intheeventof
a mechanical or electrical failure, the auxiliary switch reverts to the normally open position
and closes the gas valve.
e. ISOKERN IBV Model Firerplace
AnIsokernmodelIBV36orIBV46replaceisstandardforthereplacesystem.Thereplaces 
 aremadespecicallyforB-ventconnectionbutcanbeadaptedtototherventmaterials.Each 
 replaceueincludesanactuator/balancingdampersystemthatinterlockswiththethermallimit 
 circuitoftheburner,whichcontrolsthegasvalvefeedingthereplace.Eachreplaceisinstalled
with one of three iginition options: push-to start (manual), remote control pilot or electronic ignition.

3.1 General
The code requirements for a mechanical draft system are different than those for a gravity venting system
used with gas applications. Generally, the mechanical draft system must be installed a minimum of 3 feet
away from any forced air inlet located within 10 feet and a minimum of 4 feet away from any door
or window. For complete information, consult ENERVEX or your local building codes.
Installation must be in accordance with these instructions and all local codes, or in their
absence, the National Fuel Gas Code, NFPA 54/ANSI 223.1.
This installation manual is for the ENERVEX venting system and assumes that the ISOKERN replaces
have already been installed. Installion of the ISOKERN replaces, the gas logs and the pilot assembly
should be performed by a qualied ISOKERN technician or a certied gas service agent or supplier. If you
have any questions regarding installation of these components, consult the ISOKERN installation manual.
ImportantinformationaboutISOKERNIBVreplaces
• ISOKERNIBVmodelreplacesaredesignedforusewithstandardB-vent.ENERVEXdoesnotrecommend 
installing more than 100’ of B-vent in the vertical run of the system. If the common vertical vent is over
100’, you must use a listed pressure stack or another alternative. For information on circumstances where it is
appropriate to use B-vent in a vertical common vent greater than 100’, contact ENERVEX.
• Iftemperaturesinthereboxexceed160°F,theISOKERNIBVreplacehasathermallimitswitchthat 
opens the safety circuit and closes the gas valve.
DO NOT mount the transducer inside an airtight enclosure. It uses the room pressure
as reference pressure.
!Adequate intake air must be provided for combustion of the replaces; otherwise,
improper operation and inadequate venting of deadly ue gases may result.

To set the damper positions:
   1. Beginwiththereplaceclosesttothefan.
2. All dampers should be closed except for the one being set.
3. Set the damper to 45o. To test the appropriate damper position:
