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 balanced flue.
4 The installer must amend the boiler data label if the type of fuel or nozzle used is changed.
5 When commissioning, or when the output or fuel is changed, the air damper must be adjusted to obtain the correct CO
6 Boiler House models: When used with a balanced flue, the air intake grille on the burner must be replaced with the air intake
spigot supplied with the flue kit. The air intake hose must be attached to the burner spigot using the clip supplied.
7 50/90 System boiler: It is necessary to adjust the top baffle plate and exchange the burner head when setting the boiler to
50 000 or 60 000 Btu/h output.
8 Net flue gas temperatures given are ± 10%.
9 * Indicates the factory set output.
