1. BURNER DESCRIPTION
One stage light oil burner.
ATTENTION
If the burner is to be combined with a hot air generator in Germany (WLE according to DIN 4794), the flame control
must be replaced with a Riello 550 SMD flame control (remove the bridge), and the flame sensor must be replaced
with the amplified type (both fully interchangeable). This flame control, combined with the "remote reset kit" (which
can be ordered separately), means that the burner can be reset by remote control.
