Explanation of symbols and safety instructions
HOpen flue operation
The installation location must be adequately ventilated, if the heat
source draws its combustion air from the room.
▶ Never cover or reduce the size of ventilation openings in doors,
windows and walls.
▶ Consult a contractor to ensure that ventilation requirements are met:
– If structural modifications are made (e.g. replacing windows and
doors)
– If devices with an air discharge to the outside are subsequently
installed (e.g. extractor fans, kitchen fans or air conditioning
units).
HCombustion air/ambient air
The air in the installation location must be free of flammable or
chemically aggressive substances.
▶ Do not store or use any flammable or explosive materials (paper,
petrol, thinners, paints, etc.) in the vicinity of the heat source.
▶ Do not store or use any corrosive substances (solvents, adhesives,
chlorinated cleaning agents, etc.) in the vicinity of the heat source.
HFrost damage
If the heating system is not in a frost-proof room and is not in operation,
it may freeze up when exposed to frost. In summer mode or if heating
mode is blocked, only the device frost protection remains active.
▶ Leave the heating system switched on at all times whenever possible,
and set the flow temperature to at least 30 °C,
-or-
▶ Have a competent person drain the heating system and DHW
pipework at the lowest point.
-or-
▶ Have a competent person mix antifreeze into the heating water and
drain the DHW circuit.
▶ Check every two years whether the minimum frost protection is still
ensured.
