4 Description of the boiler
The ATAG Q boiler is a room sealed, condensing and modulating central heating boiler,
with or without an integrated hot water facility.
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 ue gasses condensate is
formed. This results in high efciency. The condensate, which has no effect on the heat
exchanger and the function of the boiler, is drained through an 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.
When an outside sensor is connected to the boiler works weather dependantly. This
means that the boiler control measures the outside temperature and ow temperature.
With this data the boiler calculates the optimal ow temperature for the installation.
Explanation of the type indication: ATAG Q 51C
Q = Type
51 = Nominal load in kW
C = Combi (S = Solo)
The boiler has been tested according to valid CE* standards and has a CE* certicate
and SEDBUK A-rating.
Statement: No banned materials including asbestos, mercury, CFC's have not or will not
be included in the product.
Room sealed boiler
The boiler retreives its
combustion air to out-
side then discharges
the ue gasses to the
outside.
Condensing
Retrieves heat from
the ue gasses. Water
condensates on the
heat exchanger.
Modulating
Higher or lower burning
according to the heat
demand.
Stainless
Super solid kind of
steel which keeps its
quality for life. It will
not rust or erode in
contrast to composition
materials, like alumi-
nium.
