The above performance figures are based on ideal laboratory test conditions. The air shutter settings above may need to be revised to take into consideration the
difference in resistances between conventional and balanced flue installations, air temperature and nozzle tolerance. Use flue gas analyzer to achieve optimum results.
Danfoss eS nozzles are a Kerosene nozzle and have a tolerance of +- 5%. Danfoss S + H nozzles are a Diesel nozzle and have a tolerance of +- 15% when used with Kerosene.

variations in nozzle throughput, flue type & draught, oil viscosity etc. may give results differing from
the below laboratory performance figures. these settings were carried out using a conventional flue.
The burner nozzle, pump pressure and air setting may have to be changed from the factory setting to suit site conditions.

1. establish the type of fuel in the oil tank.
2. Check that the nozzle type, pump pressure and air settings are as per the manual for the output required.
3. Set the thermostat to the minimum temperature and let the boiler run until it cuts out at 60˚C.
4. The boiler must be at 60˚C or higher before any adjustments or analysing is carried out.
By doing this, you are also ensuring the thermostat is working.
5. Increase the thermostat setting to refire the burner.
6. Wait for the CO

to stabilise.
7. adjust the air and pump pressure to achieve a stable CO
2
in the region of 11.5%
(refer to graph under Commissioning & Burner Settings).
8. The fuel option on the flue gas analyser should be set to a light oil.
