SAFETY INSTRUCTIONS
All persons handling 230 V power systems must be qualified in accordance with
government regulations applicable in your country.
8.1
What to Do in Case of Power Outage
In the event of mains power failure to the automatic regulation process, there is no need to reduce
or stop heating, regardless of which phase the burning control program was in at the time of the
outage. However, unless you have purchased the return spring shutter option, keep in mind that the
air intake shutter will have remained in whatever position it was in before power failed.
If you subsequently need to refuel, it is
essential
to manually open the air intake shutter to the 100%
position.
If your heating system includes a water heat exchanger, you cannot continue heating
during a power outage. Potentially dangerous unmonitored increases in exchanger water
temperature and pressure could occur, as the water pump cannot circulate and cool the
water.
Once electric power has been restored, no further manual changes to the combustion control system
are required.
If your installation includes a water heat exchanger, we recommend you purchase our backup power
supply.
8.1.1
Manually opening the EAI shutter
The EAI shutter can be manually opened using the plastic handle attached to its shaft. Turn the
handle clockwise as far as it will go. (Avoid using excessive force to prevent damage to the silicon seal
of the shutter.)
