Operating

Safety

The SHR boiler is a room sealed, condensing
and modulating central heating boiler, with
or
withoutanintegratedhotwaterfacility.
The boiler is provided with a compact stainless
steel heat exchanger with smooth tubes. A
well
thought out principal using durable materials.
The boiler burns gas for supplying warmth.
The
heat is transferred in the heat exchanger to
the
water in the central heating system. By
cooling
down the flue gasses condensate is formed.
This
results in high efficiency. The condensate,
which
has no effect on the heat exchanger and
the
functionoftheboiler,isdrainedthroughan
internal
siphon.
The boiler is provided with an intelligent control
system (CMS Control Management System).
The
boiler anticipates the heat demand of the
central
heating system or the hot water facility.
Whenanoutsidesensorisconnectedtotheboiler,
theboilerworksweatherdependantly.This
means
that the boiler control measures the
outside
temperature and flow temperature. With this
data
the boiler calculates the optimal flow
temperature
for the installation.
Q

Operating
instructions
Stainless
Super solid kind of
steel
which keeps its quality
for

Modulating
Higher or lower burning
according to the heat
demand.
Condensing
Retrieves heat from the
flue gasses. Water
condensates on the heat
exchanger.
Room sealed boiler
The boiler retreives
its
combustionairfrom
outside
then discharges the
flue
gasses to the outside.
Description of the boiler

The efficiency of the boiler is very high and the
radiation convection and standby losses very
low.
The emission of noxious substances is far
below
the fixed standards so the boiler meets
the
requirements of SEDBUK Class A.
Example SEDBUK ClassA
When the boiler is connected to a Brain Q
or Smart a lot of information can be retrieved
from
the boiler. For more information about
the
thermostats. Please refer to the user manuals.
On the left side of the boiler there is a small door.

When a type of installation has been chosen with a low water-
flow
temperature
it is possible that in case of a severe winter period the temperature of
the
heating system will need to be increased slightly. In such situations
the
installation choice may need to be changed, so that a higher flow
temperature
can be chosen. This adjustment would normally be carried out by your
installer
during the installation and commissioning.
