1.

Check the running speed of the fan (12.5 "Display the selected

appliance")

 

 

 

 

2.

Check that the hoses on the pressure switch and the air supply

 

 

 

 

 

hose between fan and burner are correctly fitted. Refit them if

 

 

 

 

 

necessary

 

 

 

 

3.

Check for cracks in the hoses on the pressure switch and in the

 

 

 

 

 

air supply hose between fan and burner. If necessary, replace

 

 

 

 

 

the hoses.

 

 

 

 

4.

Check that the flue gas outlet is compliant (3.9 "Air supply and

 

 

 

 

 

flue").

 

 

 

 

5.

Check for blockage in the flue gas discharge. Remove any

 

 

 

 

 

blockage that may be present

 

 

 

 

6.

Check for blockage in the condensation water discharge.

 

 

 

 

 

Remove any blockage that may be present.

 

 

 

 

7.

Measure the pressure differential across the pressure switch.

 

 

 

 

 

See the table in Preparation for

 

 

 

 

 

maintenance (15.2 "Preparation for maintenance"). If there is

 

 

 

 

 

insufficient pressure differential, clean the heat exchanger. If the

 

 

 

 

 

pressure differential is acceptable, check that the pressure

 

 

 

 

 

switch is closing, using a multimeter.
