P3
– potentiometer, which defines operating period for running the air fan after
a STOP signal (at absence of START signal) has been received by the burner;
P4
– potentiometer, which defines operating period for ignition of the initial fuel
doze;
P5
– potentiometer, which defines operating value of the photosensor
sensitivity;
EXPLANATION :
A common criteria for the quality of a combustion process
is its natural color. In case that this color is rather dark yellow and smoke eddies
are observed, this indicates that the fuel flow rate exceeds the optimal one for
the current air flow rate and should be decreased by setting the potentiometer on
the interface board to a lower position. The air flow control flap could be opened
as well. The objective of the adjustment is to achieve stable intensive and
turbulent combustion process and minimal char/unburned residue
. In practice
however, the factory preset values of the operating parameters do not require
any adjustment, even when the fuel has been changed.
