General

Standard inspection and maintenance operations

58
The cast aluminium/silicon heat exchanger forms the heart of the boiler.
When combined with the special geometric shape, the flue gas pollution
remains limited. Nevertheless, we recommend cleaning the flue gas side
of the heat exchanger thoroughly during the annual inspection and
service.
Boilers must be inspected at least once a year or every 3000 operating
hours.
Caution
Maintenance operations must be completed by a qualified
installer.
During inspection or maintenance work, always replace all
gaskets of the disassembled parts.
Replace defective or worn parts with original spare parts.
Important
Adjust the frequency of inspection and service to the conditions of
use. This applies especially to boilers in constant use (for specific
processes).
Important
For work on the C 630 ECO boiler: The features and instructions
described apply to each boiler module.
Warning
Always wear safety goggles and a dust mask during cleaning work
(involving compressed air).
For a service, always perform the following standard inspection and
maintenance operations.
Caution
Check whether all gaskets have been positioned properly
(absolutely flat in the appropriate groove means they are gas
tight).
During the inspection and maintenance operations, water
(drops, splashes) must never come into contact with the
electrical parts.
10.2.1

Preparation

Preparation prior to commencing inspection and maintenance activities:
1. First heat the boiler on high for about 5 minutes (return temperature
65ºC) to dry the heat exchanger on the flue gas side.
10.2.2

Checking the water pressure

1. IniControl: Check the water pressure that is shown on the display
(only if a hydraulic pressure sensor is connected).
2. DIEMATIC iSystem: If the water pressure is below 0.8 bar, the
symbol will flash (only if a hydraulic pressure sensor is connected).
3. If necessary, top up the central heating system.
