ADJUSTING THE MAXIMUM CAPACITY OF THE BURNER
Position the selector, situated on the control panel, on position maximum power and proceed as follows:
Adjusting the maximum gas flow rate: - proceed as stated in the regulating the solenoid valves until you achieve the
correct gas flow, as established by analyzing the combustion process. Eventually adjust the gas flow rate using a suitable
allen wrench, alter the position of the cam(3) guide blade; if you screw it down, the flow rate is reduced; if you
unscrew it, the flow rate increases.
Adjusting the maximum air flow rate: Eventually adjust this position acting on the screw "1 ", after loosening nut " 2
". Tighten the nut "2" in place once again.
ADJUSTING THE MINIMUM CAPACITY OF THE BURNER
Position the selector, situated on the control panel, on position minimum power and proceed as follows:
Adjusting the minimum gas flow rate: using a suitable Allen wrench, alter the position of the cam(3) guide blade; if
you screw it down, the flow rate is reduced; if you unscrew it, the flow rate increases.
Adjusting the minimum air flow rate: adjust on limit switch for air damper "Low Flame" position adjustment.
ADJUSTING THE INTERMEDIATE BURNER CAPACITIES
Using the selector, start the servomotor (closing or opening) and position on 0 to stop the stroke; the adjustment is
made as outlined below. Repeat the operation for the other cam points.
Adjusting the intermediate gas flow rates: using a suitable Allen wrench, alter the position of the cam(3) guide blade;
if you screw it down, the flow rate is reduced; if you unscrew it, the flow rate increases.
WARNING: In order to have a correct combustion and thermal output adjustments, these must be carried out
together with a combustion analysis, to be executed through suitable devices, taking care that the values are the correct
ones and are in accordance with the local safety regulations. The adjustments must be carried out by qualified and skil-
led technicians authorised by ECOFLAM BRUCIATORI S.p.A..
The adjustment of the position of the firing head is made to obtain
the best combustion performance. When used at the minimum
power output the firing head is move back, whilst is forwarded at
the maximum output. Execution : -loosen the locking screw of
adjusting device A; - move the adjusting device until the desired
position is reached; - tighten the locking screw.
