Adjusting the gas-control
In principle, it is
not
necessary to adjust the gas control after putting the unit into operation.
In case it needs to be adjusted, (e.g. after fitting a new one), this must be done only by a
qualified person.
Only use calibrated instruments!
A poor adjustment can lead to
overheating and / or production of toxic carbon monoxide!
The burner pressures can be adjusted as follows:
- Remove the cover from the gascontrol with the help of a (small) screwdriver.
-
Start the unit and first set the high burner pressure by turning screw (external 10mm).
The High / low coil must be energised !
-
De-energise coil (disconnect wire) and set low burner pressure by turning screw (slot for
screwdriver) Do not set lower than 3 mbar in order to avoid problems with inter-lightning of
burnerstrips.
TR10 up to 50
TR60 up to 125
Attention: Always check each burner pressure after any adjustment, as they influence each
other.
