1.1 INTRODUCTION
The following document provides instructions on how to install the Imax Xtra 2 motorised ue damper.
The kits consist of the following parts:
1. Motorised ue damper - Shown in Fig.1.
1.2 FLUE DAMPER KIT PARTS
1.3 INSTALLING THE MOTORISED FLUE DAMPER INTO THE FLUE
Fig. 1
The motorised ue damper has a chamfer on the male end for inserting into a ue piece and a lip seal on the female end to
receive another section of ue.
Note: The 150mm diameter motorised ue damper is for use with 80kW,
120kW and 160kW Imax Xtra 2 boilers. The 200mm diameter motorised ue
damper is for use with 200kW, 240kW and 280kW Imax Xtra 2 boilers.
The ue damper is to be installed in
the vertical ue section before the
common ue header.

1.4 ELECTRICAL CONNECTIONS OF THE MOTORISED FLUE DAMPER
Turn o󰀨 the power to the boiler and then remove the front panel, as shown in the main installation manual.
Using the gure below as a guide remove the PCB cover of the ue damper as follows:
1. Unscrew the Top Screw and place somewhere safe.
2. Unscrew the Bottom Screw and place somewhere safe.
3. Pull the PCB Cover away from the Flue Damper and place somewhere safe.
Using the gures below as a guide connect the wiring to the ue damper PCB as follows:
1. Thread the ve wires though the cable grommet located on the Flue Damper Control box.
2. Connect the Live wire to Pin 1 of the screw terminal of the ue damper PCB.
3. Connect the Neutral wire to Pin 2 of the screw terminal of the ue damper PCB.
4. Connect the Earth wire to the earthing point of the Flue Damper.
5. Connect the Flue Damper Signal wire to Pin P1 of the screw terminal of the ue damper PCB.
6. Connect the Flue Damper Feedback wire to Pin P3 of the screw terminal of the ue damper PCB.

Using the gure below as a guide place the PCB cover back onto the ue damper control box as follows:
1. Slide the PCB cover back over the Flue Damper PCB.
2. Place the Top and Bottom Screws back into place and tighten to secure the PCB cover back in place.
Using the gures below as a guide connect the wiring from the ue damper to the Imax Xtra 2 as follows:
1. Remove connector I3_CN from Installation Connection I3.
2. Connect the Live wire to Pin 3 of connector I3_CN.
3. Connect the Neutral wire to Pin 2 of connector I3_CN.
4. Connect the Earth wire to Pin 1 of connector I3_CN.
5. Push connector I3_CN back into Installation Connection I3.
6. Remove connector I12_CN_B from Installation Connection I12.
7. Connect the Flue Damper Signal wire to Pin 1 of connector I12_CN_B.
8. Connect the Flue Damper Feedback wire to Pin 2 of connector I12_CN_B.
9. Push connector I12_CN_B back into Installation Connection I12.

The schematic below shows the wiring for the Flue Damper.
Turn on the power to the boiler and recommission the boiler to congure the connected motorised ue damper.
Power from main supply
MUST be the same phase
as the boiler supply.
Note: If you are adding a Motorised Flue Damper to an Imax Xtra 2 that already has a Boiler Pump controlled directly from the
boiler you must observe the following:
• The On/O󰀨 Controlled Boiler Pump MUST be converted to Modulation Controlled Boiler Pump.
• If the Boiler pump has a PWM Modulation Input available you can use the schematic shown in Figure 3.
• If the Boiler pump only has a 0-10V Modulation Input available you need to order the 0-10V Pump Kit. The schematic
showing the wiring is shown in the instructions which are provided with the kit.

INSTRUCTIONS
If you are installing an electrically operated ue damper
onto a boiler that also requires boiler pump control then
you cannot choose an on/o󰀨 controlled boiler pump.
Instead, you MUST choose a modulation controlled
boiler pump, where the modulation signal is provided by
the boiler but the power supply is provided externally to
the boiler, but MUST be on the same phase supply.
This is done at the Boiler Pump page shown by
selecting the “Modulation from Boiler” option.
If you are installing an electrically operated ue damper
onto a boiler that does not require boiler pump control
then you can select No Boiler Pump.
This is done at the Boiler Pump page shown by
selecting the “No Boiler Pump” option.
For either of the selections above you can now
congure the Flue Damper.
This is done at the Cascade Flue with Electronic
Damper Control page shown by selecting the “Yes”
option.
The user can now proceed with the conguration
of the boiler following the remainder of the
commissioning process.
