YEARLY CHECKS:
The periodical checks of the burner (combustion head, electrodes etc.) must be carried out by authorised technicians
once or twice in a year, according to burner's duty conditions.
Before going on with maintenance operations, it is advisable to proceed through a control of the burner's general state as
follows:
- Unplug the burner from supply mains.
- Close the gas cock.
- Remove burner's cover and clean fan and air intake's duct.
- Clean the combustion head and check electrodes position.
- Reassemble the whole.
- Check fittings seal.
- Check the chimney.
- Restart the burner and check combustion values
(CO2 = 9,7% (G 20); CO lower than 75 ppm).
BEFORE ANY INTERVENTION VERIFY THAT:
- The system is supplied with power and the burner is plugged in.
- Gas pressure is the correct one and the gas cock is open.
- The control devices are suitably connected.
- If all such a conditions are satisfied, start the burner by pressing the lockout rearm button and check its igni
tion sequence.
SHORT TROUBLESHOOTING:
- The burner does not start: check power switch, thermostats, motor, gas pressure, leakage control device (if any).
- The burner runs the pre-purging but switches to lockout at the end of cycle: check air pressure, fan and air
pressure switch.
- The burner runs the pre-purging but does not ignite: check electrodes installation and position, ignition cable,
ignition transformer, control box and gas solenoid valves.
- The burner ignites but switches to lockout at the expiring of safety time: check that phase and neutral are
properly connected; check ionization probe's position and connection; check control box.
- The burner ignites properly but switches to lockout after few minutes of working: check gas pressure governor
and filter, gas pressure, detection value ( 1,5 µA min.) and combustion values.
