Important general instructions for use
Only use the boiler in accordance with its designated use and
the installation and servicing instructions. Servicing and repair
must be carried out by CORGI registered installer. Only use
the boiler in combinations and with the accessories and spare
parts indicated in the installation and servicing instructions.
Other combinations, 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 distance
frame (supplied in a seperate kit).
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.
