CONTROL PANEL
On MDFL 3300 and MDFL 4000 burners the enclosure mounted on the left side of the burner serves
mainly as a housing for electrical connections, although it also contains the ignition transformers and
carries the burner On/Off switch, the Hand/Auto switch, and the Inching switch required by
modulating burners.
If supplied, the separate free-standing panel contains the programming burner controller, contactors
and other items. This enclosure carries an amber light which indicates “BURNER ON”, and a red
light which is illuminated when the burner stops as a result of “EXCESS
TEMPERATURE/PRESSURE” in the appliance.
Also located on this enclosure are the fuel selector switch and two additional neon lights. The amber
light is illuminated when “OIL” is the chosen fuel and the red light indicates that “GAS” has been
selected.
Burner Controller
The burner controller, together with the flame monitor (see below), provide a safe light-up and
shutdown sequence for the burner.
The Siemens LFL1.333 (shown on page 21) is fitted as standard.
The burners are fitted with a continuous flame supervision system which uses an ultraviolet (UV) cell
and amplifier (incorporated within the burner controller) to detect the presence of the flame.
Modulating Controller
The Siemens RWF 40 (see page 35) is fitted as standard to all fully modulating burners.
