10. Final inspection
For a good and safe operation of the appliance, the following checks must be performed prior to commissioning.
10.1 Gas tightness
3
All connections must be gas tight. Check the connections for gas tightness. The gas control can be subjected to a
maximum pressure of 50 mbar.
10.2 Gas pressure/line-pressure
The burner pressure is set at the factory; see data plate.
3
The line-pressure in house installations must be checked, because it can be wrong.
1
Check the line-pressure. See fig. 6-1 (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.
10.3 Ignition main burner
For igniting the main burner, see the User Manual.
10.3.1 First ignition of the appliance after installation or adjustments
3
- For inspection purposes, ignite the appliance without a glass pane after installation or after having performed work.
- If necessary, bleed the gas pipe.
Proceed as follows:
1. Remove the glass pane from the appliance (see section 8).
2. Ignite the appliance by means of the remote control or DRU Fire App. See section 9.1 for a step-by-step description of
the ignition process. (Go to step 11 if the burner continues to burn).
If the main burner does not ignite:
3. Reset the system by means of the remote control or DRU Fire App.
4. Repeat the ignition procedure until the main burner ignites successfully.
3
If the appliance does not ignite after three failed attempts, it will enter into a hard lock-out for 30 minutes in order to
avoid a dangerous accumulation of gas. Make sure there is no more gas present in the appliance, before a new ignition
attempt is made.
3
Consult the diagram with error messages when ignition fails after a number of attempts (see appendix 1: Malfunctions).
5. Check the flame transfer on the main burner and check that the main burner continues to burn (go to step 11 if the
burner continues to burn).
If the main burner does NOT continue to burn:
6. Mount the glass pane.
7. Reset the system by pressing the buttons ‘Ignition’ and ‘switch off’ on the remote control simultaneously.
8. Now ignite the main burner and check that it continues to burn (go to step 11 if the burner continues to burn).
3
Limit the ignition attempts with mounted glass pane to a MAXIMUM of 1 ignition attempt. Make sure there is no more
gas present in the appliance, before a new ignition attempt is made.
If the main burner again does NOT continue to burn:
9. Switch off the appliance.
10. Consult the diagram with error messages (see appendix 1: Malfunctions) (Go to step 1 once the malfunction has been
resolved).
