Adjusting the intermediate burner capacity
Gas adjustment is accomplished through LAMTEC parameters setting. Refer to LAMTEC manual attacched.
WARNING : the variable profile of the cam shall have a normal proportional
curvature in order to have good combustion values and reduce its mechanical stress breakdown.

AIR PRESSURE SWITCH CALIBRATION
The air pressure switch is provided for monitoring the pressure of the combustion air fan.
Unscrew screws A and B and remove cover C.
After the air and gas setting you have to calibrate the air switch with the burner working
on the low flame by slowly turning the relative knob clockwise until the burner locks out.
Read the value and then decrease it by 15%.
Set the pressure switch to the minimum by turning knob D to position 1.
Start the burner and keep in low flame running, while checking that combustion is
correct. Through a small cardboard, progressively obstruct the air intake until to obtain a
CO2 increase of 0,5÷0,8% or else, if a pressure gauge is available, connected to
pressure port E, until reaching a pressure drop of 1 mbar (10 mm of W.G.).
Slowly increase the adjustment value of the air pressure switch until to have the burner
lockout. Remove the obstruction from the air intake, screw on the cover C and start the
burner by pressing the control box rearm button.
WARNING: the air pressure switch shall prevent the air pressure to go below 80% from
the adjustment value in order to prevent the CO in the fumes to exceed 1% (10000 ppm).
Using the analyser try to close the air inlet and check that the burner locks out before
exceeding CO value of 1% in the fumes.
MIN GAS PRESSURE SWITCH
The gas pressure switch has the function to check that the gas pressure before the gas
valve does have the minimum pressure to make the burner running correctly.
Unscrew off and remove cover M. - Set knob N to a value equal to 60% of gas nominal
feed pressure (i.e. for natural gas nom. pressure = 20 mbar, set knob to a value of 12
mbar; for LPG nom. pressure of G30/G31- 30/37 mbar, set knob to a value of 18 mbar).
MAX GAS PRESSURE SWITCH (KIT)
The maximum gas pressure switch has the function to check that the gas pressure after
the gas train and before the head does not exceed the pre-set limits.
Max gas pressure switch: it is available as a kit for different pressure.
