Combustion Adjustment - Ecoflam AZUR 40 Manual De Instrucciones

The ignition flow rate is carefully adjusted. during test phase to 1/3 of the maximum flow rate (according to specifications).
Operations for eventual further adjustment must be carried out by skilled personnel authorized by ECOFLAM

Adjustment of the initial flow rate: it is possible to adjust the initial flow
T
rate at a value ranging from 0 and 40% of the max. flow rate. The flow
rate is adjusted by the manufacturer to an intermediate value; to modify
it, turn screw H through a screwdriver: to the right (screwing) to reduce
the flow rate and to the left (unscrewing) to increase. To find the right
adjustment, proceed a turn at a time then start the burner. Check the
initial flow rate value following the instructions given at par. "Adjusting
the gas flow rate at the ignition".
+
Adjustment of the maximum flow rate: unscrew screws A and remove the
D
cover T. Through a wrench of 12 mm turn the valve obturator D: to the
right to reduce the max. flow rate, and to the left to increase. Fit the
—
cover after the regulation.
Note: the 3 screws Q must be unscrewed only to replace the valve's coil.
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 S.p.A.
ADJUSTMENT OF PRESSURE GOVERNOR
The adjustment procedure is the same for both single-stage (MB-DLE) and two-stage (MD-ZRDLE) versions. Check
that gas pipe pressure is not higher than the maximum one specified for the governor, then operate through a screw dri-
ver fitted into the suitable seat as shown in the figure. Adjustments must be made with the burner running, in function
of the working pressure and needs of each installation. The working fields are as follows: inlet pressure range 0÷100
mbar; outlet pressure range 3,6÷20 mbar. Between the minimum and maximum outlet pressure there are approx. 60
adjusting screw's turns. The governor is adjusted to an intermediate position during the tests.
ADJUSTMENT OF GAS SOLENOID VALVES
ADJUSTING SOLENOID GAS VALVE (BRAHMA)
To adjust gas output, loo-
sen the screw B and turn
the knob C as required. To
reduce output, turn knob
clockwise, to increase it
turn knob counterclockwi-
se. Tighten the screw B.
For fast opening adjust-
ment, remove the cap T
and insert the spanner on
the pin H turning on the
requested direction. To
reduce firing output screw
it up, to increase, unscrew
it.
