Adjusting Air On The Combustion Head (Light Oil) - baltur GI 1000 Serie Mode D'emploi

ADJUSTING AIR ON THE COMBUSTION HEAD
The combustion head is fitted with an automatic device which regulates the passage of air between the disk and the
head. By throttling the passage it is possible to obtain high pressure upstream from the disk even for a low flow-rate.
Consequently, the high speed and turbulence of the air allows it to penetrate the fuel better, thus giving an optimum
mix and good flame stability. With a gas burner it may be indispensable to have high air pressure upstream from the
disk in order to avoid flame pulse. This condition is virtually a must when the burner has a pressurised combustion
chamber and/or a high heating load. It follows, then, that the device which closes off the air on the combustion head
must be adjusted in such a way as to always maintain decidedly high air pressure behind the disk.
We recommend that the air on the head be throttled to an extent that requires significant opening of the air damper
which regulates burner fan air flow. To do this act on the modulation disk adjuster screws.
When adjustment is over remember to lock the adjuster screws in place with the lock screws.
