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).

MANUAL RELEASE
SWITCH
LANDIS LGB 22 UP-CYCLE
The control box starts the burner fan, to carry out the prepurging
of the combustion chamber, and cheks the vent air pressure
through the air pressure switch. At the end of prepurging, the
ignition transformer cuts-in and generates a spark between the
electrodes. At the same time the two gas valves open (Vs safety
valve and Vl Low flame working valve). The total safety, in case
of missed ignition or casual burner's flame-out, is granted by a ionisation probe which cuts-in and sets the burner shut-
down within the safety time. In case of gas lack or a major pressure drop, the minimum air pressure switch shuts down
the burner.

”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.
LOW FLAME
