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 efciency. 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* certicate
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.
