Adjusting the gas valve R301 - R307<br />
Two screws are located at the gas valve which can be used to adjust the gas volume (CO 2 value).<br />
Run the boiler at full load and check the CO 2 value. Adjust if necessary using the flat screw<br />
(types 1 and 2) or the inbus screw (types 3 to 7).<br />
Run the boiler at minimum load and check the CO 2 value. Adjust if necessary using the torcx<br />
screw.<br />
Adjusting the air-pressure switch R301 - R307<br />
<strong>The</strong> air-pressure switch is set at 80% of the fan speed when pre-ventilating.<br />
For example:<br />
Pre-ventilating takes place at 80 rps.<br />
<strong>The</strong> air-pressure switch is set to 0.8 x 80 = 64 rps.<br />
<strong>The</strong> actual switching moment can be read on the display.<br />
If the appliance is checked in the manner indicated, and corrected as necessary, the following<br />
pressures, at full capacity, must be recorded for reference on the commissioning report note:<br />
P vent<br />
P bb<br />
P vent -P bb (measure separately!)<br />
P vh<br />
∆T.<br />
8 Maintenance<br />
8.1 Safety<br />
During maintenance activities, always wear suitable clothing and shoes. Consider your own<br />
safety, particularly in respect of jewellery and loose clothing.<br />
8.2 General<br />
In order to ensure continued good and safe operation of the appliance, this must be inspected at<br />
least once per year.<br />
<strong>The</strong> following activities must be carried out (for an extensive description of these activities, see<br />
8.3):<br />
- Renew the ignition and ionisation electrodes<br />
- Clean the fan blades<br />
- Clean the condensate receptacle<br />
- Clean the condensate trap and the drainage pipe from the appliance<br />
- Inspect all pressure measurement pipes and nipples<br />
- After removing the panels from the left hand side of the appliance, ignition and burning can be<br />
observed via a sight glass<br />
- Test the unit at the flue gas side for CO 2 and CO and correct these at both full and minimum<br />
capacity if necessary<br />
- Check all the safety functions, and make any necessary adjustments<br />
- Measure the water temperature difference ∆T as a measure of the flow rate<br />
- Check the water pressure<br />
- Check the water quality: hardness and chloride content<br />
- Record all data<br />
- Clean the outside of all the panels and ensure that these all have a smart appearance.<br />
