5 COMISSIONING
5.1 LIMITING BOILER MAXIMUM OUTPUT
The boiler is supplied for operation on maximum heat output of 15kW. The output can be rated below this maximum to
match the heat load required.
WARNING: ON INSTALLATIONS WHERE THE INCOMING POWER SUPPLY IS NOT CAPABLE OF
MAXIMUM LOAD THE BOILER CONTROL MUST BE RE-CONFIGURED TO LIMIT THE OUTPUT BEFORE
SWITCHING ON.
As the output for Domestic Hot Water will also be limited to the same level it is recommended to adjust to the highest
output possible so as to maintain the best hot water performance.
The boiler will not exceed this pre-set maximum but will still modulate in heating mode up to this level, adapting to
demand and ensuring economic operation.
Adjustment is made by selecting the desired position of switches numbered 1 to 4 in a block situated on the main PCB.
The PCB is located after isolating from the mains, removing the case and tilting the control panel.
The switches are positioned upside down as shown below.

With a small screwdriver move the switches to correspond to the positions shown in the tables for the required output,
referring to a single or three phase supply.
Correct configuration for the selected output can be checked on the boiler display panel following the procedure shown
in 7.4 CHECKING RATED HEAT OUTPUT.
CAUTION: It is essential to confirm the power output with the use of a clamp meter.
