Airtight gas convectors
SYSTEMA S.p.A.
7) Check for leakage of gas along the threaded joints.
8) Fire the device, and make sure that the supply pressure to the burner is 29 mbar (*) using
the pressure tap (5).
9) Indicate on the rating plate the type of gas transformation performed on the device.
(*) For LPG gas (Butane-Propane), a “I” stage pressure reducer must be installed near the
tank in order to reduce the pressure to 1.5 bar; a “II” stage pressure reducer must be installed
on the main external supply line in order to reduce the pressure to 29mbar (0.029 bar).
Transformation from LPG gas to Methane gas
1) Close the gas supply line and disconnect the electrical power supply.
2) Remove the cast-iron front panel by unscrewing the four M8 screws at the corners.
3) Remove the gas supply line pipe from the main burner (4) using the sealing connector (5)
(See Draw ).
4) Remove the nozzle-holder (6) and the nozzle (7), and replace the nozzle with the one
contained in the transformation kit after first checking to make sure that the diameter
corresponds to the diameter listed on the rating plate.
5) Re-close the cast-iron front panel, making sure that the fiberglass sealing liner remains in
place.
6) Check for leakage of gas along the threaded joints.
7) With a 20 mbar supply pressure read on the pressure tap (2), use the adjustment screw
(3) to bring the pressure of the burner (1) to its nominal rating plate value. Screwing in the
clockwise direction increases the pressure, while unscrewing counter-clockwise decreases
the pressure.
8) Indicate on the rating plate the type of gas transformation performed on the device.
