Remove cover to gain access to the adjusting cams.The cams are to be adjusted
through the suitable key provided for. Description:
I-Limit switch for air damper “High Flame” position adjustment
(Max. power)
II - Limit switch for the air damper position at burner’s shut down
III - Limit switch for air damper “Low Flame” position adjustment
(Min. power)
V-Limit switch for 2nd stages solenoid valve opening release
NOTE :
Cam V (to allow the 2nd stages solenoid valve opening) must be adjusted to an
intermediate position between the Low and High Flame ones (to an angle
approximately 5° greater than the low flame position).

”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 acting on the screw “1 “,
after loosening nut “ 2 “.
3. Regulate gas capacity in high flame through the gas governor, or operate on the adjustable gas valve.
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 burner to low flame.
5. Regulate gas capacity, to obtain optimal combustion, changing the position of the gas valve disc, act on screw “ 3 “,
after loosen nut “ 4 “.
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.
