Note 1
The primary air damper should remain at the position indicated. The secondary air damper settings are
for guidance only; individual site conditions—such as the type of flue and level of draught—will often compel
deviation from the recommended positions. See fig 3 for air damper adjustment instructions.
Note 2
The CO
2
ratio is correct for a combustion air temperature of 20°C; see fig 2 for other temperatures.
Note 3
The * indicates factory settings. To attain different outputs, changes to the nozzle specification, pump
pressure and air setting may be required. The boiler should be set to match the heat requirements of the
system. Incorrect matching may impede the boiler's correct operation and invalidate its warranty.
