Important general instructions for use
Only use the boiler in accordance with its designated use and
the installation and maintenance instructions. Installation,
maintenance and repair must be carried out by competent
service engineers (e.g. CORGI registered). Only use the boiler
in conjunction with the accessories and spare parts indicated
in the installation and maintenance instructions. Other
accessories and consumables may only be used if they are
expressly provided for the designated use and if system
performance and safety are not affected in any way.
The boiler is suitable for connection to fully pumped, sealed
water systems ONLY. Adequate arrangements for completely
draining the system by provision of draining valves must be
provided in the installation pipework.
Pipework from the boiler is routed downwards as standard, but
may be routed upwards behind the boiler using the wall
spacing frame.
Subject to technical modifications.
As a result of our policy of constant development, there may be
small differences between illustrations, functional steps and
technical data.
