Response SE Combi -
Installation
GENERAL
Ancillary pipework not forming part of the useful heating surface
should be lagged to prevent heat loss and any possible freezing -
particularly where pipes run through roof spaces or ventilated
underfloor spaces.
Draining taps should be at least 1/2" BSP nominal size and be in
accordance with BS 2879.
Maximum recommended system hydraulic losses are given in
within Frame 4.
WATER TREATMENT
The Response SE has an aluminium heat exchanger. If water
treatment is used Caradon Plumbing Limited recommend only the
of Fernox-Copal or Sentinel X100 water treatment products,
which must be used in accordance with the manufacturers'
instructions. For further information contact either:

BOILER WATER CONNECTIONS
Notes.
1.
It is most important that the correct concentration of the water
treatment product is maintained in accordance with the
manufacturers' instruction.
2.
If the boiler is installed in an existing system any unsuitable
additives must be removed by thorough cleansing. BS.
7593:1992 details the steps necessary to clean a domestic
central heating system.
3.
In hard water areas treatment to prevent limescale may be
necessary. However, the use of artificially softened water is
not permitted.
4.
Under no circumstances should the boiler be fired before the
system has been thoroughly flushed.
THERMOSTATIC RADIATOR VALVES (TRV)
Caradon Plumbing Limited
recommend that heating systems
utilising full thermostatic radiator valve control of temperature in
individual rooms should also be fitted with a room thermostat
controlling the temperature in a space served by radiators not
fitted with such a valve as stated in BS. 5449.
When thermostatic radiator valves are used a bypass should be
fitted, ensuring it is at least 3m from the boiler. The bypass
should have at least 6m of flow and return pipe of a minimum
22mm diameter.
