"PAB" VERSION GAS BURNERS GAS TRAIN INSTALLATION AND SETTING INSTRUCTIONS

Fix the gas train to burner body by means of the screws of the flange, pay attention to set correctly the gasket. Connect

electrically the gas train with the 6 pole plug.

Switch on the burner (it has already been tested in the factory, so it is pre set on average values) and verify the tightness

of gas train connections made during installation. Act as follows to adapt the burner output to the boiler.

High flame

1. Bring the burner in high flame , air inlet must be set at 75 ° (maximum opening position).

To adjust air capacity operate on the combustion head position. Just in peculiar case it is necessary to reduce the air

flow in high flame closing air intake damper.

2. The position of gas butterfly valve must be lower then 90° ( typically 85°. It is important not get over 90° to obtain

a perfect combustion during passage from high to low flame). Eventually adjust this position by shaft B after

loosening the screw A.

3. Regulate gas capacity in high flame through the gas governor, or operate on the adjustable gas valve.

Attention: the instructions for gas valves setting are included in the gas train manual.

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 bur

ner to low flame.

5. Regulate gas capacity, to obtain optimal combu

stion. 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.

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.
