Kerosene Notes:
1 The data given above is approximate only and is based on the boiler being used with a low level balanced flue.
2 The above settings may have to be adjusted on site for the correct operation of the burner.
3 Gas Oil is not suitable for use with low level balanced flue models, unless the flue terminal is higher than 2.0 m above
outside ground level.
4 The installer must amend the boiler data label if the type of fuel or nozzle used is changed.
5 The 50/70, 70/90and 90/140 models use Riello burners. The 140/160 and 160/200 models use EOGB Sterling 90
burners.
6 * Indicates the factory set output.
7 ** Net thermal efficiency (BSRIA).
8 The net flue gas temperatures given above are ± 10%.
9 When commissioning, or when the output or fuel is changed, the air damper must be adjusted to obtain the correct
CO
2
level and the installer must amend the data label.
10 When downrating the 50/70 model to 50 000 or 60 000 Btu/h, an LD2 head must be fitted.
