STARTING UP AND REGULATION
• Disconnect the thermostat (if connected) to prevent 2nd stage
activation.
• Slightly open the air regulator (see BT 8653/1) and let in an
amount of air deemed necessary for burner operation with the
1st stage and lock it in this position; set the air control device in
an intermediate position on the combustion head (see chapter
“Adjusting the air on the combustion head”).
• Close the main switch and the equipment switch on the synoptic
panel (1).
• The small motor of the cyclic relay which will start to rotate
causing the connection of the burner component devices
according to the preset program. The burner ignites as described
in chapter “Operation description”.
• When the burner is working in the 1st stage, regulate the air to
ensure a good combustion (see BT 8653/1). It is better if the
amount of air for the 1st stage is slightly reduced in order to
ensure a perfect ignition even in the most critical conditions.
• After adjusting the air for the 1st stage the burner stops, cutting
off the voltage to the main switch. The terminals of the 4-pole
connector of 2nd flame thermostat connect and the 1st and 2nd
stage switch (3) moves to the 2nd stage position.
• Adjust combustion air for the 2nd stage.
• Now connect the burner again; it will start and automatically
switch to the 2nd stage, according to the preset program.
• With the equipment operating with the 2nd flame, adjust
(BT 8563/1) the amount of air necessary to ensure efficient
combustion.
DISTANCE REGULATION BETWEEN
DISC AND NOZZLE
The burners are equipped with a device that allows the distance
between disc and nozzle to be varied. The factory set distance
between disc and nozzle should be reduced only if you notice that
the cone of atomised fuel coming out of the nozzle wets the disc
fouling it.
