* NOTE: The flue gas temperature is measured in the flue. The probe should be inserted to a depth of 150mm in the center of the flue. The temperature measured is not an absolute flue
gas temperature and is for general guidance purposes only! **NOTE: Class C2 28sec kerosene.
NOTE: The pump pressure given is for general guidance only as variations in nozzle output can be up to ± 15%. It is, therefore, essential that the air is adjusted to give the correct CO
2
value.
NOTE: The nozzle type used on 28 Sec. Kerosene outputs are nozzles calibrated specifically for use with 28 Sec. Kerosene which gives less variation in nozzle output than the standard
35 Sec. Gas Oil nozzles. However, if a 28 Sec. Kerosene nozzle is not available at servicing or commissioning it is appropriate to install a 35 Sec. Gas Oil nozzle providing the output, spray
angle and pattern of the nozzle is the same as the 28 Sec. Kerosene nozzle (e.g. 0.560°ES may be replaced with a 0.560°S).
