Inspection and maintenance work – Overview
C
No.
Work
Check the air/flue pipe for leak-tightness and to ensure that it is fastened correctly. Make sure
1
that it is not blocked or damaged and has been installed in accordance with the relevant Installa-
tion Manual.
Check the general condition of the unit. Remove dirt from the product and from the combustion
2
chamber.
Visually inspect the general condition of the heating block. In doing so, pay particular attention
3
to signs of corrosion, rust and other defects. If you notice any damage, carry out maintenance
work.
Check the gas connection pressure at maximum heat input. If the gas connection pressure is not
4
within the specified range, carry out maintenance work.
Check the CO₂ content (the air ratio) of the product and, if necessary, adjust it. Keep a record of
5
this procedure.
Disconnect the product from the power mains. Check that the electrical plug connections and
6
other connections are seated correctly and correct these if necessary.
7
Close the gas isolator cock and the service valves.
Drain the product's heating circuit. Check the pre-charge pressure of the expansion vessel and
8
top up the vessel, if necessary (approx. 0.3 bar below the system filling pressure).
Allow the pressure in the hot water circuit to fall. Check the pre-charge pressure of the expan-
9
sion vessel in the shift-load cylinder (if installed). Correct the pressure, if necessary.
10
Check the extent to which the anode is corroded and replace it if necessary.
Remove the compact thermal module.
11
Check all seals in the combustion area, in particular the seal on the burner door. If you see any
12
damage, replace the seals.
Clean the heat exchanger.
13
Check that the burner is not damaged and, if required, replace it.
14
Check the condensate siphon in the product, clean and fill if necessary.
