Installation, Use and Maintenance
DANGER:
If you smell gas:
•
Do not use naked flames, do not smoke and do not activate
electrical contacts or switches.
• Cut the gas supply.
• Ventilate the room.
• Trace the leak and repair it.
DANGER:
If smoke is released:
•
Switch off the boiler.
• Ventilate the room.
• Trace the leak and repair it.
DANGER:
The boiler is earthed via connecting cables (green/yellow) and special
fixing screws. If the boiler is disassembled, make sure the cables are
reconnected properly and ALWAYS reuse the original fixing screws.
1.5. Water characteristics
The following rules apply once the boiler is put into service and remain valid
until the end of life of the product.
1.5.1. Preparing the water system before putting the boiler into service
For any installation (new or renovation), the water system pipes must be
thoroughly cleaned. The purpose of this initial cleaning is to eliminate germs
and residue that can cause deposits to form.
In new installations in particular, any residues of grease, oxidised metal or
copper micro-deposits must be removed.
In renovated installations, cleaning should focus on removing sludge and the
products of corrosion formed when the unit was last in operation.
There are two types of methods for cleaning and removing sludge: a high-
intensity approach that takes a few hours and a slower, more gradual
approach that takes several weeks. This first type of cleaning must be done
before connecting the new boiler, and with the second type, a filter should be
installed on the boiler return circuit to capture loosened deposits.
The cleaning performed prior to installation improves performance, reduces
energy consumption, and resists scaling and corrosion on the unit. A water
treatment professional should carry out the cleaning.
