"PAB" VERSION GAS BURNERS GAS TRAIN INSTALLATION AND SETTING INSTRUCTIONS
Fix the gas train to burner body by means of the 4 screws of the flange, pay attention to set correctly the gasket ( O-ring ).
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 rod "1 ", after
loosening nut " 2 ".
3. Regulate gas capacity in high flame through the gas governor, or operate on the adjustable gas valve.
