Low flame
4. Choose the first stage position on the servocontrol (normally between 10°-30°) on the basis of the reduced charge
output required and switch the burner to low flame.
5. Regulate gas capacity, to obtain optimal combustion. To adjust the butterfly valve position act upon hexagonal bar
C after loosening nuts D.
Final operations
6. Bring the burner in high flame again, if necessary
adjust again gas flow (as shown in point n.2).
7. If necessary repeat operations described on point n.
5 and n. 6 until You obtain the exact position of
the gas flow both in high and low flame.
8. Fix the nuts.

COMBUSTION ADJUSTMENT
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 skilled techni-
cians authorised by Ecoflam S.p.A.
SETTING THE FIRING HEAD
The firing head position adjustment is made in order to obtain the best combustion efficiency. When used with mini-
mum outputs the firing head is adjusted in rear position. With high output, the firing head is adjusted in forward posi-
tion.
Adjustment:
- Loosen screw A through a suitable Allen key. - By a screwdriver act on the hex. head screw B until is reached the desi-
red position. - Tighten screw A

CALCULATING THE BURNER CAPACITY
To calculate the burner's capacity in kW, proceed as follows: Check the gas flow rate (in liters) on
the counter and the time of the reading in seconds.
Proceed with the calculation using the following :
e x f = kW
sec
e
= Litres gas
sec = Time in second
G20 = 34,02
G30 = 116
G31 = 88
