18.3 CLEANING THE CONDENSATE TRAP
Unscrew the lower section of the water condense trap.
• Clean the bottom of the trap by ushing it out with water.
• Fill the lower section with water until about 10 mm below the upper
edge.
• Fasten the lower section onto the condense trap again.
Do not operate the boiler with empty condense trap to avoid risk
of poisoning through the gas combustions.
18.4 COMBUSTION PARAMETERS
To measure combustion efciency and the emissions of the products of combustion, the boiler is
tted with two dedicated test points. One connection point is connected to the ue gas discharge
circuit ( A), and allows monitoring of the quality of the combustion products and the combustion
efciency. The other is connected to the combustion air intake circuit ( B), allowing checking of
any recycling of the combustion products in case of coaxial pipelines. The following parameters
can be measured at the connection point on the ue gas circuit:
• temperature of the combustion products;
• oxygen ( ) or carbon dioxide ( ) concentration;
• carbon monoxide ( ) concentration.
The temperature of the combustion air must be measured on the test point located on the air intake ue (B) by inserting the me-
asurement sensor by about 90 mm (C).
To enable the “ CHIMNEY SWEEP MODE” consult section 12.3.
