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

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

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.
