• Release the three clamps (1), remove the combustion

chamber cover (2).

9.2.1 For thermoCOMPACT 615, 637 and turboMAX

plus 837

• Remove the flue gas connector (2a) on the fan.
• Remove the retaining spring (3).
• 115

5 k

W:: Pull the three cables (4) and two tubes (5) from

the fan assembly.

• 3

7 k

W:: Remove both plugs (not illustrated) and both

hoses (5) from the fan.

• Remove the fan assembly (6).
• Remove the four screws (7) and detach the front cover

panel from the combustion chamber (8).

• Check the burner (9) and heat exchanger fins (10) and

remove any loose deposits with a soft brush.

9.2.2 For thermoCOMPACT 620, 624, 628,

turboMAX pro 24, 28 and turboMAX plus 824,
828

• Pull the three cables (4) and two tubes (5) from the

fan assembly.

• Remove the fan assembly (6a, 6b, 6c).
• Remove the four screws (7) and detach the front cover

panel from the combustion chamber (8).

• Check the burner (9) and heat exchanger fins (10) and

remove any loose deposits with a soft brush.

• Reassemble in reverse order.
Check central heating expansion vessel.

Note!
It is not necessary to carry out this check every
year – a check every three years should be
sufficient.

• Release the system water pressure from the boiler.
• Remove valve cap from expansion vessel charge point.
• Check that the internal charge pressure of expansion

vessel is between 0.7 - 0.9 bar. If pressure is lower
than this the vessel should be re-pressurised using an
air pump.

• Refit valve cap.
• Open central heating service valves and re-pressurise

the boiler and heating system if necessary.

• Open the gas service valve.
• Turn on the mains power supply.
• Operate the boiler and carry out soundness, safety

and function checks.

• Complete the service interval record section in the log

book and leave with the user.
