INSTALLATION MANUAL
7. Final inspection
In order to check whether the appliance is working properly and safely, you must perform the following
inspections before the appliance is put into operation.
7.1 Gastightness
!Caution
All connections must be gastight. Check the connections for gastightness.
The gas control may be subjected to a maximum pressure of 50 mbar.
7.2 Gas pressure/line-pressure
The burner pressure is set at the factory; see data plate.
!Caution
The line-pressure in house installations must be checked, because it can be wrong.
Ø
Check the line-pressure; see Appendix 3, Fig 38 (P1) for the measuring nipple on the gas control.
•
Contact the gas company if the line-pressure is too high.
• If the line-pressure is too low, check this at the gas meter. Contact the gas company if the line-pressure is also
too low at the gas meter.
7.3 Ignition main burner
For igniting the main burner, see the User Manual.
7.3.1 First ignition of the appliance after installation or adjustments.
!Caution
After installation, or after work has been performed, you should ignite the appliance for the first time without the
glass window. If necessary, bleed the gas pipe.
Follow the procedure described below:
Ø
If necessary, remove the glass pane.
Ø
Start the ignition procedure as described in the user manual.
Ø
If the main burner does not ignite:
•
Reset the system by pressing the buttons ‘arrow up’ and ‘arrow down’ simultaneously.
• Repeat the ignition procedure until the main burner ignites;
!Caution
After each attempt to ignite, the system should be reset by means of the remote control.
Ø
Consult the diagram with error messages (Appendix 1) if this does not succeed after a few attempts;
The appliance ignites at 50%. After ionization has been detected, the appliance will modulate to 100%.
This detection will have to take place within 15 seconds, or else the appliance will enter error mode.
If applicable, the second valve will switch to ignite the second burner. Here, you can hear a clear ‘click’ sound.
Ø
Check whether the main burner continues to burn.
Ø
If the main burner does not continue to burn:
Reset the system as described and repeat the ignition procedure until the main burner continuous to burn.
!Caution
The system can be reset and re-ignited three times in a row at maximum. Then the system will enter a hard
lock-out and you will have to wait half an hour, before you can make a new attempt.
Ø
Consult the malfunction search diagram (Appendix 1) if this does not happen after a few attempts.
Ø
Switch off the appliance.
Ø
Then mount the glass window as described from chapter 5.10.
Ø
Repeat the ignition procedure a few times and perform the checks described in chapter 7.3.2.
Ø
From now on, the main burner should ignite smoothly.
Ø
Clean the glass pane after igniting for the first time (see section 8).
!Tip When checking whether the main burner continuous to burn, it is possible that it switches off after 15 seconds. In
that case, this will be caused by the fact that there is no ionization detection and because the glass window has
not been placed. This can be regarded as a situation where the main burner continues to burn.
