7 .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 is
intended for LPG, air flow monitoring using an air flow
detector set ECO must be provided. If the flue gas route
is blocked, the central air will be prevented from flowing
into the gas line or gas will be prevented from flowing
into the air line.
