BURNER START-UP
Once connected the burner to the gas pipe make sure that there are no leakages.
Air bleed the pipe through the pressure gauge fixing point and check the pressure with a pressure gauge. Turn
the thermostats to the desired temperature. The burner will purge for about 30 sec. At this point the gas valve
opens and the transformer ignites. Control the gas flow in the gas meter and adjust the needed quantity of gas
operating on the gas valve. Adjust the needed quantity of air, operating on the air regulator.
In case of no ignition the burner goes to lock-out time is less than one sec.
In case of extintion of the flame while operating lock-out time is less than one sec.
In case of lack or descreasing of air pressure, the air pressure switch shutts off the gas valve.
GAS GOVERNOR
The governor does not form part of the burner accessories and therefore technical instruc-
tions on the adjustement of this component have been omitted. However it is important
to know the folling points:
1-The gas pressure in the gas-mains must not exceed the maximum permitted pressure
for the governor.
2-Every governor is furnished with several springs, usually identified by their colour, each
allowing a range of setting.
It is necessary to select the correct spring to suit the pressure required on the burner.

DIFFERENCES OF L.P.G. BURNERS IN COMPARISON WITH NATURAL GAS BURNERS.
NATURAL GAS L.P.G.( 70% PROPAN - 30% BUTAN)
CALORIFIC POWER : kcal/Nm38.600 kcal/Nm322.000
kcal/kg 11.800
L.P.G. burners must be installed with two pressure reducers. First reducer, that normally is installed on the tank, reduces
pressure down to 1.5 bar. Second reducer from 1.5 bar to 37÷50 mbar. Gas pressure in the tank can reach 10-12 bars. For
the above explained reasons special attention should be taken on following operations items:
l. Regulation of gas flow, keeping in mind that L.P.G. has almost three times the calorific power of NATURAL GAS.
2. It is very usefull to install a pressure gauge after the second pressure reducer and before the gas train.
3. It is recommended to install n.2 gas valves in series instead of one.
4. Strongly recommended gas filter must de installed before burner gas train.
5. To calculate the proper gas quantity in absence of GAS METER, this should be done trough combustion
control and specially on the exhaust gases temperature checking.

Max output adjustment is
to be made by inserting
and elbow spanner in the
socket S situated at the
bottom of the valve and
turning to the left to
increase output, to the
right to reduce it.

To adjust gas output, loosed
the screw B and turn the
knob C as required. To reduce
output, turn knob clockwise,
to increase it turn knob coun-
ter-clockwise. Tighten the
screw B. For fast opening
adjustment, remove the cap T
and insert the spanner on the
pin H turning on the reque-
sted direction. To reduce
firing output screw it up, to
increase, unscrew it.

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.
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 FLOW RATE FOR SINGLE-STAGE VERSION (MB-DLE)
To adjust the gas flow rate, loosen screw R and turn the regulator; to the right (screwing) to reduce; to the left
(unscrewing) to increase. At the end tighten screw R.
