6 .8 .3 Operation with LPG

GEH
For operation with LPG, it is essential to cool the gas
lance via a central air lance in order to prevent the LPG
from cracking in the gas lance and soot formation dur-
ing combustion.
The central air volume is approx. 3 to 5% of the com-
bustion air volume and must also flow while the burner
is switched off.
ECOMAX · Edition 10.17
GEH
Open the adjuster in the central air lance fully. On the
ECOMAX 1, the adjuster must be restricted to 45° or 50%.
If high temperature operation without flame control
using ionization or a UV sensor is intended for LPG, air
flow monitoring using an ECO air flow detector set must
be provided to prevent backflow of the central air into
the gas line or of gas into the air line in the event of the
flue gas route being blocked.
