NOTE
Adjusting the air flaps in the plus direction increases the air
quantity, adjustment in the minus direction reduces the air
quantity.
Measure water temperature
Install the shut-off valve with thermometer (special tool)
on the appliance outlet.
Switch on the burner and bring the appliance to working
pressure with full water volume via the shut-off valve.
Let the device run in burner operation for approx. 5 min-
utes until the maximum water temperature is reached.
Measure the increase in water temperature (water out-
let temperature minus water supply flow temperature).
Measure the air pressure on the burner cover (special
tool) and adjust it on the air slider.
Measure the soot value, CO2 content and the exhaust
temperature (special tools, measuring gauges).
Adjusting the fuel pressure
Set the fuel pressure (and water temperature) via the
set screw.
Adjusting the soot value
If the soot value is too high, then the air flap needs to
be opened further or the fuel pressure needs to be re-
duced.
Adjust the CO
2
value
Adjust the CO
2
value by moving the air flap. Open the
air flap, the CO
2
content is decreasing.
NOTE
After finishing the basic adjustment, the fuel pump and the
air flap must be sealed.
