12.5 Inspection and maintenance
▶
You must carry out an annual inspection of the product.
The annual inspection can be effectively performed
without removing components by requesting data from
the Diagnostics codes, carrying out the simple visual
checks indicated in the table in the appendix and per-
forming a flue gas measurement. The maintenance
intervals and their scope are determined by the heating
engineer based on the condition of the boiler found
during the inspection. All inspection and maintenance
work should be performed in the order specified in the
table in the appendix.
During any inspection and maintenance or after change
of parts of the combustion circuit, the following must be
checked:
–
The boiler has been installed in accordance with the rel-
evant installation instructions.
–
The integrity of the flue gas installation and flue seals is
in accordance with the relevant flue installation instruc-
tions enclosed.
–
Visual, the integrity of the boiler combustion circuit and
relevant seals (paying particular attention to the burner
door seal).
–
The gas inlet working pressure at maximum rate.
–
The gas flow rates.
–
Correctness of electrical, water and gas connections.
–
Correctness of the water pressure.
–
The condition of the whole system, in particular the con-
dition of radiator valves, evidence of leakage from the
heating system and dripping taps.
▶
Correct any faults before proceeding.

12.7.1 Removing the compact thermal module
Danger!
Risk of death and risk of material damage
caused by hot flue gas.
The seal, insulating mat and self-locking nuts
on the burner flange must not be damaged.
Otherwise, hot flue gases may escape and
cause personal injury and material damage.
▶
Replace the seal each time you open the
burner flange.
▶
Replace the self-locking nuts on the
burner flange each time you open the
burner flange.
▶
If the insulating mat on the burner flange
or on the back wall of the heat exchanger
shows signs of damage, replace the insu-
lating mat.
1. Disconnect the product from the power supply.
2. Close the gas stopcock.
3. Remove the front casing. (
