2.1 Description
1. The appliance incorporates a Stirling engine which is capable of
generating between 0.4 – 1.0 kW of electrical power depending on
the running conditions of the heating system. High return
temperatures especially above 65°C will reduce the power generation.
It is therefore in the interests of the householder to ensure that the
central heating system is maintained and working as efficiently as
possible. Balance the radiators in the central heating system so that
there is suitable drop in temperature across each radiator. 20°C is
optimum for new systems but some older radiators originally installed
with non condensing appliances may only manage 11°C.
2. The use of a programmable room unit incorporating a room
sensors (as apposed to a room thermostat) will also improve the
power generation.
3. If the return temperature to the appliance gets too hot the engine
burner will switch off to protect the engine – in this case the
supplementary burner will light on its own until the return
temperature has cooled sufficiently and the engine burner will be
enabled again.
4. The electricity generated in this manner if not consumed directly by
the user is fed back into the grid. Arrangements can be made with the
electricity provider to compensate the householder by way of a feed-
in tariff. See section 13.3.
5. It is your responsibility to contact your electricity supplier and
inform them that you have installed a Baxi Ecogen which will generate
electricity. This is a legal requirement.
6. Operation and control is similar to a domestic boiler and is fully
automatic.
7. All interactions with the appliance are either through the removable
Programmable Operator Unit (POU) on the front of the appliance or
on a remote wall cradle.
2.2 Important Notes
1. Read and follow these instructions thoroughly before switching on
and operating this appliance. These instructions must be followed and
warning labels must be adhered to.
2. As with any domestic boiler, flammable materials MUST NOT be
placed near this appliance and materials emitting flammable vapours
must not be stored in the same room.
Do not position a kettle or toaster directly below the appliance.
3. The appliance MUST NOT be tampered with, abused or any sealed
components adjusted as this may result in a hazardous situation.
4. Please note that because of the high efficiency of the appliance,
condensate (water) is produced from the flue gases. A condensate
‘plume’ (water vapour) may also be seen coming out of the flue.
Gas Connection
5. Your Baxi Ecogen appliance has been installed by a Gas Safe
registered installer– this is both good safe working practice and
complies with the current gas safety regulations.
Electrical Connection
6. Your Baxi Ecogen appliance has been installed in accordance with
the Installation Instructions, this means that:
The appliance has been earthed.
The electricity supply to the appliance is 230V ~ 50Hz.
7. Connection to the electricity supply has been made in a way that
allows complete isolation of the electricity supply from the appliance.
The isolation switch is located in an accessible position within your
installation.
8. It is a legal requirement that both the District Network Operator
(DNO) and the electricity provider are informed of the installation of
this appliance - see section 13.3.
NOTE: In the event of a power failure the appliance will turn off
automatically and will not restart for at least 3 minutes after the
power supply has been restored.
