5.9.1 Checking for tightness of the flue gas
installation and flue gas recirculation
>
Check the integrity off the flue gas installation
according to TB 200.
>
Should the flue gas installation be longer than 2 m we
strongly recommend to check the system for flue gas
recirculation as described below.

Legend:
1 Flue gas measure point
2 Air measure point
>
For checking the system for recirculation use the air
measure point (
2 ).
>
Use the flue gas analyser.
>
If you detect any CO or CO
2
in the fresh air, search for
the flue gas leakage or recirculation.
>
Correct the defects.
>
Check again as described before, if there is any CO or
CO
2
in the fresh air.
>
If you cannot correct the defects you must not start
up the boiler.
5.9.2 Checking the gas flow rate
The boiler is fitted with a multifunctional automatic gas
valve which ensures that the precise air/gas ratio is
provided under all operating conditions. The gas flow
rate has been set during production and does not
require adjustment. With the front casing fitted check
the gas flow rate of the boiler as follows:
>
Start the boiler by activating the test program P.1 as
described in section 8.2.
>
In addition, ensure that maximum heat can be dissi-
pated into the heating system by turning up the room
thermostat.
>
Alternatively, for ecoTEC combination boilers fully
open the hot water taps to ensure full flow rate
through the boiler.
>
Wait at least 5 minutes until the boiler has reached its
operating temperature.
>
Ensure that all other gas appliances in the property
are turned off.
>
Measure the gas flow rate at the gas meter.
>
Check that the gas flow rate is as stated in Table 5.1.
