Information on installation and operation
For the installation and operation of the heating system,
observe all country-specific standards and guidelines.
The information on the data plate is binding and must be
observed.
3.1
Combustion air quality
▶ Keep the supply of combustion air free of corrosive substances
(e.g. halogenated hydrocarbons that contain chlorine or fluorine
compounds).
This will help to prevent corrosion.
▶ Never use or store chlorinated cleaning agents or halogenated
hydrocarbons (as contained in spray cans, solvents or cleaning
agents, paints and adhesives, for example) in the boiler room.
▶ Keep the combustion air supply free of dust.
▶ If building work is taking place in the installation room and creating a
lot of dust, shut the boiler down. A burner contaminated during
building work must be cleaned before commissioning.
▶ Ventilation ducts/openings are not to be blocked
3.2
Heating water quality
Ensure that ventilation and bleeding openings are not reduced in size or
sealed.
The quality of the fill and top-up water is an essential factor for increased
efficiency, functional reliability, long service life and for maintaining the
constant operational condition of a heating system. If the system is filled
with water that has a high calcium hardness, this will be deposited on the
heat exchanger surfaces and will restrict the transfer of heat to the
heating water. As a result, the wall temperatures of the heat exchanger
surfaces will rise and the thermal stresses (loads on the boiler body) will
increase.
This is why the quality of the fill or top-up water must meet the conditions
stipulated in the operator's log provided and be recorded in this log.
The conditions for boilers > 600 kW require general water treatment
independent of the water hardness and the volume of fill and top-up
water.
