GETTING IN OPErATION
The device can start only if it is connected to the boiler by a chimney, providing enough traction, there is a pressure and
pellets from the pellet transporter.
Requirements for supplying pellets during the burner start:
- the auger transporter must be placed in a way, so that it can easy get pellets from the bunker.
- the auger transporter’s cable must be plugged in for the primary auger loading (the down plug, placed on the left side of
the burner).
ATTENTION
•
THE DOWN PLUG IS CONSTANTLY UNDER PRESSURE AND IS DESIGNED FOR PRIMARY AUGER’S LOADING,
and the other plug is for normal work.
This is shown by stickers on the contact-plug and the pin-plug the boiler must be started with thermostat set the way,
so there is no setting from the thermostat to the burner or the burner’s switch (POWER), feeding its control,
must be turned off (the switch must be placed downside).
In this case the auger gets feeding pressure from the down plug (which is always under pressure as soon as
the boiler works) and it starts to transport pellets.
When the first pellets pass the highest point and start falling down by the flexible tube to the burner, the auger
transporter’s cable must be plugged in the plug for the auger’s normal work (the upper plug, placed on the
burner’s left side), the burner’s switch must be turned on (in must point upside), the thermostat must be set at
a desired temperature (80–90°C) and the burner is ready for work.
Normal start (example):
The boiler must be turned on by the main switch and the thermostat must be set at 80-90°C.
In this case the burner is fed with pressure (the POWER light is on), there is a signal from the boiler to the burner to start
(the RUN light is on) and the burner starts for executing the preset algorithm.
The starting algorithm is as follows:
- The auger transporter, the ignition helix and the fan are on;
- After the preset (from the manufacturer) time is up, providing feeding with a dose of pellets for the primary ignition, the
auger transporter turns off;
- When the pfoto sensor in the burner detects light, the feeding to the ignition helix stops.
There is time for burning of first dosage (PARAMETER T7);
- After that the device starts its normal work, proceeds to pellets feeding and pause for their burning.
The times for pellets feeding – parameter T4 and pause for their burning – parameter T6 can be set from the user.
The feeding, the burning time and the quantity of the air supplying which can be controlled by the fan valve of the burner,
are parameters showing the flue gases temperature;
- After reaching the set water temperature in the boiler, (for example 85°C), the boiler’s thermostat stops the start-signal
to the burner and the burner turns off.
The fan stays turned on for about 5 min. (parameter T5, set by the manufacturer) so that the pellets in the burner’s head
will burn out.
After the temperature falls and follows starting-signal from the thermostat, the burner turns on again;
- If during work the set temperature goes down, the burner will turn off;
- If during rest when a set temperature is being increased, then the burner will turn on;
- If the pellets don’t ignite, a new attempt for their burning will start automatically;
- If the sensor does not detect any flame during work, the ignite algorithm will start again;
