Note: All boilers are despatched for use with kerosene.
Notes:
1 The data given above is approximate only. The Kerosene table 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 a low level balanced flue, 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 and nozzle used are changed.
5 Net flue gas temperatures given are ± 10%.
6 ** Net thermal efficiency (BSRIA).
7 Flue gas temperatures taken at combustion door test point will be approximately 25°C higher for the Combi 90 V3 and
Combi Max.
8 Flue gas temperature taken at the top of the boiler will be 20°C higher for the Combi 70 V3.
