IDEA boilers are supplied for use on Natural Gas. Should they be used with LPG, just ask for gas transformation kit to be sent for changing from Natural Gas to LPG.

Changing from Natural Gas to LPG:
- Exchange the injectors of main burner.
- Fully tighten the pressure regulator screw and replace the pressure regulator cap by the one (without
hole) supplied with the kit.
- Check the burner pressure upstream the gas valve and set the pressure regulator according to values
quoted on Technical Data Table 1.4.
- Check that burner pressure value downstream the gas valve corresponds to what reported on
Technical Data Table 1.4. Seal the pressure regulating screw.

IDEA BOILERS WITH ELECTRONIC IGNITION
- Turn the boiler thermostat dial to the required temperature. As soon as gas flows
from the main burner, the ignition electrode will spark.
If not, check that the correct voltage is being supplied to the gas control valve.
- If there is voltage, then replace the gas control.
- If there is no voltage, then check the function of main switch, flue safety thermostat, time clock, room thermostat, boiler control thermostat.
- Ensure that electrode spark is 5 mm. long and that it shoot out between ignition
plug and gas outlet slots on the burner.
If there is spark but main burner does not ignite, ensure that:
- gas installation has been completely vented;
- voltage arrives to gas valve.
If the burner lights but the ignition spark keeps operating and after a few seconds
the ionisation control trips, ensure that:
- on control panel phase is connected to pole 1 and neutral to pole 2;
- ionisation plug is not broken or incorrectly positioned or damaged because of
humidity;
- installation has been correctly earthed and that the earth cable conneceted to
the burner is adequately secured.
- Turn off the boiler main switch. Remove the test point screw downstream the burner. Move the water column manometer to the pressure test point downstream the
boiler. Refit the inlet test screw. When burner is fully ignited, set the burner gas
pressure to the pressure shown in the technical data table 1.4 according to the gas
type used. Seal the adjustment screw.
- Switch the burner off using the main switch. Wait 30 seconds at least. Re-light the
burner and check the slow ignition (approx. value: 8 mbar.).
