9.5 Flushing the heating installation for the first
time ("cold")
Note
The complete heating system must be flushed
at least twice: Once with cold water and once
with hot water in accordance with the following
instructions.
1. Check whether all thermostatic radiator valves and both
service valves on the product are open.
2. Connect a hose to the drain valve that is located at the
lowest position in the heating system.
3. Open the radiator valves and the drain valves so that
the water can drain quickly. Start at the next point in the
installation and open the purging valves on the radiators
so that the contaminated water can completely drain.
4. Close the drain cocks.
5. Refill the heating system with water.
6. Close the filling valve and the cold water tap.

lator of the gas valve assembly.
9.7.1 Checking the air/flue pipe/flue gas
recirculation
1. Check the flue gas installation is intact in accordance
with the latest gas safe technical bulletin and informa-
tion supplied in the installation instructions.
2. For extended flue gas installations check for flue gas
recirculation using the air analysis point.
3. Use a flue gas analyser.
4. If you discover unusual levels of CO or CO
ply air, search for the leak in the flue system or for signs
of flue gas recirculation..
5. Eliminate the damage properly.
6. Check again whether the supply air contains any CO or
CO .

7. If you cannot eliminate the damage, do not start up the
product.
9.7.2 Checking the gas flow rate
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 up the product with the check programme P.01.
▶
In addition, ensure that maximum heat can be dissipated
into the heating system by turning up the room thermo-
stat.
▶
Wait at least 5 minutes until the boiler has reached its
operating temperature.
