CONCENTRIC VERTICAL FLUE
15. Once the length of the vertical concentric extension has been determined mark and carefully cut off the excess material. The cut end MUST be square and free of burrs to
ensure correct insertion into the boiler adaptor.
16. Measure 25mm from the end of the flue extension and apply a length of tape around the outer duct ( Fig. 38 ).
17. Engage the extension into the adaptor up to this position ( Fig. 39 ). Once the installation of the flue is complete and all support brackets are securely in place remove the
tape.

10.1 Making The Electrical Connections
This appliance shall be connected to a suitably protected electrical supply i.e., 16A ­ see section 7.7.
NOTE: Ensure all cables are secured using the cable clamps provided.
When accessing the appliance controls area, take care not to let the control box
drop down in an uncontrolled manner as this may cause damage.
1. To gain access to the controls tray / electrical wiring area, remove the outercase by lifting off the plastic fascia that is held on by two magnets. Undo the two screws
holding the outercase, pull the bottom edge forward, lift and disengage from the top of the appliance ( Fig. 40 ).
2. Slacken the four screws from the bottom cover and remove the cover ( Fig. 40 ).
3. Remove the two screws holding the control tray. Pull the front of the control tray forward and lower it carefully ( Fig. 41 ). DO NOT allow the tray to fall in an uncontrolled
manner.
4. Ensure all cables are secured using the cable clamps provided.
5. Ensure that the lengths of the live and neutral conductors are shorter that the earth conductor, so that if the cable slips in its anchorage the current carrying conductors
become taut before the earth conductor.

10.2 System installation options.
1. There are two installation options available, Intelligent and Retro. Y­plan, S­plan, W­plan and S­Plan with a second heating circuit are all available both with Intelligent
and Retro installations.
IMPORTANT: Before running the appliance ensure parameter 5700 has been set according to the type of system installed.
See
sections 10.4 to 10.11 for system types and section 11.3. k for the change procedure.
A) An Intelligent system operates the Ecogen with room sensors, an optional extra outdoor sensor (an outdoor sensor can only be installed in conjunction with a room sensor to
enable weather compensation), a DHW tank sensor or DHW tank thermostat and will give the highest overall efficiency with increased electrical power generation and is therefore
the recommended way to install the appliance.
The Removable THINK Controller must be used as a Programmable Room Sensor for all intelligent installation.
