5.3.1 Requirements for the installation room
Notice
The installation room must be dry and frost-free.
Caution
Do not stock chloride or fluoride compounds close to the boiler.
They are particularly corrosive and may contaminate the
combustion air. Chloride and fluoride compounds are present in
aerosol sprays, paints, solvents, cleaning products, washing
products, detergents, glues, snow clearing salts.
Warning
Risk of damage!
The condensing boiler may only be installed in rooms with clean
combustion air. Foreign matter such as pollen must never filter
through the inlet apertures to reach the inside of the appliance.
The boiler must not be started up if there is heavy dust
development e.g. during construction work. There could be
damage to the boiler.
Danger
Changes to conducts for combustion air and flue gas are only
allowed after consultation with the district chimney sweep
responsible. Such changes include:
Making the set-up location smaller
Retrofitting joint-sealed windows and outside doors
Sealing windows and outside doors
Covering or removing supply air apertures
Covering chimneys
Caution
Keep the inflow area clear.
Never block or close off ventilation apertures. The inflow area for
combustion air must be kept clear.
Important
There are inspection apertures for the chimney sweep in the flue
gas spigot on top of the boiler.
Ensure that these inspection apertures are always accessible.
