7.3.2 Instructions for burner setting
The oil burner is factory-set for a certain output range
(see tab. 7-1, values printed in bold).
To change the burner output:
– Change the pump pressure,
– Adjust air quantity,
– Distance oil nozzle / air nozzle setting (tab. 7-1, dimension
"Y"),
– if big adjustment has been made to output: change oil nozzle
and air nozzle (changeover kit).
Conversion kit
To set some output ranges, a conversion kit URS is needed
(see tab. 7-1).
Certain changeover sets also contain, in addition to a suitable oil
nozzle, an air nozzle with a different flow cross-section
(see section 7.5).
Oil nozzles
For retention of the minimum emission values ROTEX recom-
mends using the
Danfoss
oil nozzles of the
Type 80° H
(see tab. 7-1).
