Combustion System Commissioning
To ensure correct operation of the combustion system the gas valve must be set at Maximum and
Minimum outputs.
The commissioning mode can be activated regardless of the operating status of the heating and how
water control system. If zone or mixing valves are installed within the system ensure that these are open
to allow for complete circulation of the generated heat.
The High Fire commissioning mode is activated by pressing the MODE & + buttons simultaneously.
The Low Fire commissioning mode is activated by pressing the MODE & - buttons simultaneously.
To leave the commissioning mode press the RESET button or the + & - Button simultaneously.
It is advisable to check the combustion figures on High and Low Fire prior to carrying out any
adjustments.
Adjusting the High Fire has a marked effect on the Low Fire figures. Where as adjusting the Low Fire has
little effect on the High Fire figures.
The High fire adjustment is carried out via red sheathed screw (4).
The High Fire adjustment is a Gate type restrictor.
Therefore turning the screw clockwise will close the Gate and thus restrict the quantity of gas passing
through to the burner.
The Low fire adjustment is carried out via the 4mm TORX head (2).
The Low Fire adjustment is a diaphragm governor.
Therefore turning the screw clockwise will increase the pressure on the diaphragm and thus increase the
quantity of gas passing through to the burner.
