Bosch BSS250E-2 Installation And User Manual page 17

Adequate provision must be made to dispose of any water escaping from heater or adjacent
plumbing that might result in damage to property.
The water heater must be connected in such a way that:
Electrical covers are accessible to a service agent.
Space is allowed for the removal of the heating element.
The pump is accessible for servicing.
or complete removal of the unit if necessary.
CONFINED SPACES
If the thermostat fails the unit may produce excessive steam.
It is strongly recommended that the heater should be installed in a well-ventilated space to
avoid condensation build up.
If installed in confined areas, make provision for Service Access.
FOUNDATION
To ensure adequate tank support, position the unit on an approved support base such as a
concrete slab (See figure below).
Alternative forms of water heater bases are acceptable providing they allow for adequate
support.
Attention is drawn to the weight of the water heater tank when full (approx 460kgs) and
installer should ensure that the base and footings are substantial enough to avoid subsidence
etc.
To comply with NZBC G12 Building code, please install cylinders with seismic straps as shown
on Page 18.
