FUEL HEATING

In order to obtain smooth starting and operation across

its output range the burner is fitted with an electric

resistance, which heats up the gas oil in the nozzle

line. This resistance is energized when the thermostat

calls for heat and after a delay of approximately two

minutes depending on room temperature, the motor

will start. The resistance remains inserted and locks-

out on the shut-down of the burner.

Attention

Should you want to cut off the electric resistance (on

setting the burner or when the ambient temperature

does not require it, etc. . .), take the plug off the panel

of the control box and plug it into the "Resistance

(see fig. 8). In this case the burner starts

OFF"

up when the thermostats close.

NOTE

The warning light (LED) is ON but when the resist-

ance works. It is OFF when the resistance is discon-

nected or broken.

DETECTION

DEVICE -

Only for type 447T1

NORMAL OPERATION

The plug fitted in the panel is placed in the position corre-

sponding to "Resistance ON"

When the remote control closes, the LED lights up and,

after about two minutes, the burner starts up.

BURNER DOES NOT OPERATE

1) If the LED is OFF, the heating resistance placed

in the nozzle-holder is off.

2) If the LED is ON and nevertheless the burner does not run, place the plug in the position corre-

sponding to "Resistance OFF"

the control box is out of order.

3) If the motor does not run, it means that the failure is neither in the panel nor in the resistance, but

elsewhere.
