- Setting the CO
2
value for the R30 series
There is a fl at setting screw on the venturi with which the CO
2
value can be set at full load. Set
the boiler at full load and check the CO
2
value.
If necessary, adjust with the fl at setting screw: clockwise gives less CO
2
, anti-clockwise gives
more CO
2
.
There is a torcx setting screw on the gas valve with which the CO
2
value can be set at minimum
load. Set the boiler at minimum load and check the CO
2
value. If necessary, readjust with the
torcx setting screw: clockwise gives less CO
2
, anti-clockwise gives more CO
2
. After the CO
2
values have been set, they should be checked once again and corrected if necessary.
- Conversion from natural gas to propane.
For the types R30/45, R30/65, R30/85 and R30/100, a throttle ring will be required for pro-
pane. This should be installed between the gas valve and venturi. After the conversion, the CO
2
values should be set at full load and minimum load.
For the type R30/120 it’s only necessary to change the gas volume on the gas valve by using
the setting screws.
Type
Diameter of throttle ring
R30/45
6.8 mm
R30/65
6.0 mm
R30/85
6.0 mm
R30/100
6.8 mm
- Remove the measuring equipment and re-fi t the case
- The boiler is now ready for operation
8 Maintenance
8.1 Safety
Wear suitable clothing and shoes for maintenance work. Before you wear jewellery and loose
clothing, think of your safety.
8.2 General
In order to ensure the proper and safe working of the boiler for a long period of time, it should be
inspected at least once a year.
The following operations should be carried out (for a more extensive description of these opera-
tions, see 8.3):
- Replace the ignition and ionisation electrodes
- Clean the fan impeller
- Clean the boiler condensate bottle trap and the drain pipe
- Clean the gas fi lter (if there is one)
- After removing the casing, you can look at the front side with a sight glass at the ignition and
combustion (fl ame picture)
- Test the boiler combustion for CO
2
and CO and if necessary correct the same at minimum load
and at full load
- Measure the water temperature difference ∆t as a measure of the fl ow rate
- Check the water pressure
- Inspect the water quality: hardness and chloride contents
- Clean the casing on the outside and ensure that it looks clean again
