Air damper setting (A).
To act on the screw in figure:
• to increase output,
turn screwdriver clockwise
• to reduce output,
turn screwdriver counterclockwise
!
Risk of air blast!
Continuously check CO, CO 2 and soot emissions when adjusting the output of
the burner. Optimise combustion values in the event of CO formation. CO must
not exceed 50 ppm.
Pre-setting diagrams in appendix
Before start-up adjust the burner
parameters according to the settings given
in the diagrams for GAS/LPG.
These values have been determined in
our test labs and are useful for the first
switch-on as final setting must be done
using a combustion analyzer.
How to read and adjust the values:
- determine the output required
- determine the combustion chamber back-
pressure
- read the position of the head in the
diagram and adjust it according.
- read the position of the air flap and adjust
it according.

The diagrams of air/head setting
that are available in the appendix
of this manual are a guide for ensuring
that the burner functions as well as
possible.

Refer to the gas train manual for the gas
setting of the gas train selected.
Note: observe the minimum required
flue gas temperature specified by the
boiler manufacturer and the
requirements demanded of flue gas
ducts for avoiding condensation.
