Combustion Adjustment - Ecoflam BLU 1700.1 PR Manual De Instrucciones

B LB 509 BLU 1700.1 - 2000.1 PR / MD
Adjusting the maximum air flow rate (see figure, detail 2). Loosen the nut holding the air damper transmission rod;
The correct air flow as established by analyzing the combustion process.
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.
Adjustment the intermediate gas flow rates (see figure, detail 3): - using a suitable Allen wrench, change the position of
the cam guide blade; if you screw it down, the flow rate is reduced; if you unscrew it, the flow rate increases.
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 :
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.
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 desired position. - Tighten screw A
