General Instructions
The burner must be fed with the type of fuel for which it is arranged, as specified on the unit's dataplate
and in the technical data table in chap. 4.3 of this manual.
The user is advised to use good quality pellets, since low quality pellets result in low heat outputs, high
ash content with subsequent need of frequent cleaning, possible early wear of burner parts exposed to
the fire, clogging of the auger and burner due to excess loose sawdust, and operation shutdowns due
to sedimentation of unburnt materials inside the burner.

Pellet loading
Pellet loading can be activated within 40 minutes of switching on the power to the burner.
Within this time, the system makes available three 5-minute attempts, during which only the auger is
activated.
The burner cannot be lit during pellet loading.
Sequence:
1. Switch on the power to the burner.
2. Wait for the pre-ventilation stage to end.
3. Press the programming button "P" (detail 5 - fig. 1) for 10 seconds.
- The parameter "tø1" is displayed: identified by the message SET 01.
- Set the parameter to 1 to start the first 5-minute attempt. It can be stopped at any time by setting
the parameter 0.
- If the first attempt was insufficient, repeat the previous sequence, setting the parameter to 0 and then
to 1: for the second and third loading attempt.
4. To carry out another 3 attempts, switch power to the unit off and then on again.
