916067 01.13 1. Product Information 1.1 Function Use The ENERVEX ADC100 Draft Control is a fan speed and appliance control used to control draft for a gas appliance such as a fireplace, stove or furnace. It may be interlocked with the appliance and is for use in systems where modulation is not required. It controls the speed of a fan to maintain proper draft and pressure in a chimney system.

3916067 01.13 3. Mechanical Installation 3.1 Location The ADC100 Control Unit must be installed indoors. 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 connected to the fan, appliance and damper (if used). For detailed wiring information, see Chapter 4. ADC100 Fig. 1 ADC100 ADC100 DAMPER (SOLD SEPARATELY) ENERVEX PDS1 ENERVEX 3.2 Mounting the Control Unit The ADC100 control may be mounted directly to a wall.
3916067 01.13 3.3 Connection of the Proven Draft Switch and Stack Probe The Proven Draft Switch (PDS) must be installed indoors, in the vertical position (pre-drilled knockouts face down). Mount the control upright to a wall or other flat surface. Do NOT lay the control down or mount horizontally. A Proven Draft Switch (PDS) must be used with the ADC100 control as a system safety device.
3916067 01.13 3.5 Adjusting the Fan Speed and Post Purge Time There are two potentiometers located on the main control board of the ADC100. To increase the fan speed, rotate the potentiometer labeled Fan Spd clockwise. Alternately, rotating the potentiometer counterclockwise will decrease the fan speed. In Manual mode, the potentiometer can be adjusted at any time during normal operation to increase or decrease the fan speed.
3916067 01.13 4. Electrical Installation 4.1 General Danger: Turn off electrical power before servicing. Contact with live electric components can cause shock or death. ADC100 is designed for 1x120VAC power supply only. The designations for each terminal on the control board are shown below. Note that some installations may not require the use of all terminals. Also shown in this section is a general connection diagram for an ADC100 control system. Fig.
3916067 01.13 4.2 Connection Diagram The connection diagram shown in Fig. 7 below shows typical connections for a single phase fan. If a 3-phase fan is used, a VFD must be connected between the fan and control. Fig.
3916067 01.13 4.3 Wiring of a Gas Fireplace To interlock the ADC100 with a gas fireplace as shown in Fig. 8, connect the Auxiliary In terminals 9 and 10 on the control board to a wall switch. Either by using line voltage or use board voltage from terminals 7 and 8 as depicted in figure 8. Connect the gas valve or ignition to Auxiliary Out at terminals 22 and 23. The Auxiliary Out is a normally open dry contact that closes when the PDS closes and releases the fireplace for operation.
3916067 01.13 4.4 Wiring of a Gas Fireplace with a Damper To interlock the ADC100 with a gas fireplace as shown in Fig. 9, connect the Auxiliary In terminals 9 and 10 on the control board to a wall switch. Either by using line voltage or use board voltage from terminals 7 and 8 as depicted in figure 8. Connect the gas valve or ignition to Auxiliary Out at terminals 22 and 23.
3916067 01.13 4.5 Wiring a 3-Phase Fan Connect a 3-phase fan to the control system via a variable frequency drive (VFD). The VFD receives external 3-phase power (208-230 or 400-480 VAC). A 0-10 VDC signal from the ADC100 is converted to a 0-60 Hz signal from the VFD to modulate the fan speed. Any appliance(s) or damper should be connected as shown in Fig 8 and 9. Fig.
3916067 01.13 5. Startup and Configuration 5.1 General Dip switches are located on the control board to allow the user to specify certain functions of the ADC100. Verify settings using the table below.
3916067 01.13 5.2 Sequence of Operation The sequence of operation flow chart is shown in figure 11 below. Fig.
3916067 01.13 Automatic Mode: 1. Fan runs at speed setting of the potentiometer but cannot be adjusted using the potentiometer during operation. 2. If the Proven Draft Switch opens, the fan begins to ramp up. 3. If PDS closes, fan speed remains at that speed. 4. If the PDS has not closed by the time the fan has ramped up to 100% speed, a 10 second timing cycle begins. 5. If PDS does not close within 15 seconds the auxiliary out contact opens and an alarm condition exists. 6.
