Description of the boiler
The ATAG QR boiler is a room sealed, condensing and modulating central heating boiler,
with or without an integrated hot water facility. This boiler is also approved for use as an
open flued boiler according to flue category B23 and B33.
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 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, the boiler works weather depen
-
dantly. 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.
Room sealed boiler
The boiler retreives its
combustion air from outsi-
de then discharges the flue
gasses to the outside.
Condensing
Retrieves heat from the
flue gasses. Water con
-
densates on the heat
exchanger.
Modulating
Higher or lower burning
according to the heat
demand.
Stainless steel
Super solid kind of steel
which keeps its quality for
life. It will not rust or erode
in contrast to composition
materials, like aluminium.
2 Safety
Work on the installation should only be carried out by qualified personnel with calibrated
equipment. When replacing parts, only ATAG Service components may be used.
The device may be operated only by authorized persons who have been instruc
-
ted on the operation and use of the device. Improper use may cause damage to
the device and / or to the connected installation.
ATAG do not recommend that children play with the appliance at any time.
The appliance is not to be used by children or persons with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless
they have been given supervision or instruction.
In case you smell gas:
-
No naked flames! Do not smoke!
-
Do not operate electrical switches for lights or any other appliance.
-
Do not use a telephone
-
Turn off gas supply at meter
-
Open windows and doors
-
Notify any persons in the building and leave the building at once.
-
Call Gas company or installer only when outside the building
Protection for corrosion
Do not use any sprays, chlorine containing agents, solvents, paint etc. around the
boiler or around the air intake supply entrance of the boiler. These substances have
negative influences on the boiler and can lead to corrosion resulting in failure of the
boiler.
Checking the water pressure
Check the water pressure in the central heating installation regularly.
Use only potable water for filling.
Additives only after clearance by ATAG.
Contact your installer in case of doubt.
