WHEN REPLACEMENT IS NECESSARY, PROCEED AS SHOWN IN FIGURES A-B-C BELOW
Insert the RWF 40 regulator through the relative opening in the electrical panel (A).
Insert the fixing anchors and screws into the slots, and secure the unit to the panel (B).
To open the regulator, squeeze the cover from the ends as shown, and lift out (C).
ANNUAL CHECK
The burner (combustion head, electrodes, etc.) must be checked regularly by an authorized technician, once or twice a
year, depending on how much it is used. Before proceeding withe the maintenance check-up on the burner, it is advisa-
ble to check the general condition of the burner and take the following steps: Disconnect the burner (remove the plug).
- Close the gas shut-off cock. - Remove the cover from the burner, clean the fan and air intake. - Clean the combustion
head and check the position of the electrodes. - Re-install the parts. - Check the seal on the gas connectors. - Check the
state of the flue. - Start the burner.
- Check the combustion parameters (CO2 = 9.5 to 9.8% CO; O = less than 75 ppm).
BEFORE TAKING ANY ACTION, CHECK:
- that there is power in the circit and the burner is connected; - that the gas pressure is right and the gas shut-off cock is
open; - that the control systems are properly connected. If all these conditions have been satisfied, start the burner by
pressing the reset button. Check the burner cycle.
IF THE BURNER FAILS TO START: check the switch, the thermostats, the motor and the gas pressure.
IF THE BURNER PROCEEDS WITH PREVENTILATION BUT CUTS OUT AT THE END OF THE CYCLE:
check the air pressure and the fan. Check the air pressure switch.
IF THE BURNER PROCEEDS WITH PREVENTILATION BUT DOES NOT LIGHT: check the installation and
position of the electrodes. Check the ignition cable. Check the ignition transformer. Check the safety device.
IF THE BURNER LIGHTS BUT CUTS OUT AFTER THE SAFETY INTERVAL: check that the phase and neu-
tral wires are connected correctly. Check the gas solenoid valve. Check the position and connection of the detector elec-
trode. Check the detector electrode. Check the safety device.
IF THE BURNER LIGHTS BUT CUTS OUT AFTER OPERATING FOR A FEW MINUTES:
check the pressure regulator and gas filter. Check the gas pressure with a pressure gauge. Check the detector value
(at least 6 µA).
