Note1:
All gas flow rates are referred to Stm
(net calorific value H
Note2: Maximum gas pressure = 360 mbar (with Dungs MBDLE)
Minimum gas pressure = see gas curves.
Note3: Burners are suitable only for indoor operation with a maximum relative humidity of 80 %
Note4: with electrode: for safety reasons the burner must stop automatically every 24 hours
(*) NOTE ON THE BURNER WORKING SERVICE: LMV2x automatically stops after 24h of continuous working. The device immedia-
telystarts up, automatically. LMV3x performs countinuous operation (with electrode only).
