3.2 Packaging
To avoid damaging the water heater, remove the packaging carefully.
We recommend unpacking the water heater at or near its intended location.
Caution
The water heater may only be manoeuvred in an upright position. Take care
that the water heater is not damaged after unpacking.
3.3 Ambient conditions
The water heater is suitable for either open or room-sealed combustion. If
installed as a room-sealed water heater, it is independent of the installation
site for the necessary external air supply. In this event, there are no additional
ventilation requirements.
If the water heater is to be installed as an open system, it must meet the
locally-applicable directives and ventilation regulations for open water
heaters.
The possible installation types are B23, C13, C33, C43, C53 and C63.
Caution
The water heater may not be used in rooms where chemical substances are
stored or used due to the risk of explosion, and corrosion of the water heater.
Some propellants, bleaching agents and degreasing agents etc. disperse
vapours that are explosive and/or cause accelerated corrosion. If the water
heater is used in a room in which such substances are present, the warranty will
be void.
