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 net flue gas temperatures given above are ± 10%.
6
The 70/90 and 90/140 models use Riello RDB burners. The 140/160 and 160/200 models use EOGB Sterling 90 burners.
7
* Net thermal efficiency (BSRIA).
8
** Flue gas temperatures taken at combustion door test point will be approximately 25°C higher.
