1.5 Burner description
The burners B-Home Round 25 and B-Essential Round 50 are very versatile and are able to cover a great many functions, from
installation on new generation boilers, bread ovens and hot air generators to the transformation of old boilers
They are made up of a round combustion head, a variable-speed main ventilator, a reliable start-up system, thanks to the
flame detection photocell, an internal cochlea for feeding the fuel and they are designed so a compressed-air self-cleaning
kit can be installed.
They must be completed with a fuel feeding system made up of a cochlea, with a flexible tube connected to the burner and
by a pellet container, which is supplied separately , as an accessory.
The burners and the whole system are managed by a control panel with a microprocessor fitted onto the device, which,
as well as managing all the functions, also permits the programming of time bands; this is useful so the machine only runs
when it is needed.
1.6 Safety devices
The burners B-Home Round 25 and B-Essential Round 50 are fitted with the following safety devices:
–Burner safety thermostat
–Firebreak valve (optional)

1.11 Running
The running of the appliance is controlled from a control panel with a microprocessor which programmes the following
phases:
–When a request for heat is sent in start-up mode the main fan, the external cochlea and the internal loading cochlea start
up to supply the necessary quantity of pellets for ignition. The internal cochlea starts up 8 seconds later than the external
cochlea;
–When the pellet loading for ignition is finished, the ignition resistance is powered electrically, and this ignites the flame
the brightness of which is recorded by the photocell within a max. of 20 minutes (safety time). In the event of non-ignition,
the burner goes into SHUTDOWN mode. In the event of a SHUTDOWN, in order to reactivate normal running conditions,
it is necessary to disconnect the appliance from the mains, remove the cause of the malfunction, and then reconnect it to
the power supply;
–After the flame has been correctly detected, the appliance starts to run normally with a gradual increase in power supply
until the maximum value programmed is reached, and the appliance continues to operate in modulation until the pro-
grammed water temperature for the boiler is reached, or that of a water storage heater if one is installed. While the burner
is running, the external and internal cochleas also work according to the programmed ON and OFF times;
–Once the programmed temperature has been reached, the cochleas, both internal and external, are stopped by the control
panel, and the pellets remaining in the combustion chamber continue to burn;
–When the brightness of the photocell goes below 20 lux, the fan speed increases to clear the combustion chamber of the
last residue and then it stops.
The burner is then ready for the next start-up.
m
WARNING CAUTION
–The programming of the parameters MUST be carried out EXCLUSIVELY BY QUALIFIED TECHNICIANS AUTHOR-
ISED BY
Elmec Group S.r.l. , and only after the Password has been given.
–For the working and shut-down periods of the burner, whether the "time bands" are activated or not should
be taken into consideration.
–If the COMPRESSED AIR KIT is also present, cleaning of the combustion chamber takes place at the beginning
and at the end of each operational cycle of the burner.

3 STARTUP
3.1 Before starting up the burner
Before starting up the appliance check that:
–the burner is correctly mounted on the boiler door and that this latter is firmly closed
–the cochlea and the burner flexible connection hose are positioned correctly
–the pellet container has been filled
–the water temperature probe has been correctly positioned
–the boiler and the plant has been filled with water
–the hydraulic circuit valves are open
–the fumes exhaust duct has been set up properly.
3.2 First ignition
Connect the burner power supply, positioning the plant main switch and the main burner switch in the "ON" position , and
check that the screen lights up.
The burner has already been calibrated for maximum power in the factory, so for the first ignition just press the Fkey for
about 2 seconds and wait for the flame to light.
Leave the burner in the continuous running mode, at maximum power for about 15 minutes, and then with a flue gas analys-
er check that the values recorded are close to the ones indicated in the table:
Description U/M Correct vlaue
O2% ~ 10
CO (average) mg/cm3< 500
Exhaust temperature °C 120 ÷ 200
Press the Fkey to turn off the burner and leave it to cool.
l
WARNING
This operation must be carried out ONLY by authorised and qualified technicians.
3.3 Checks to carry out after the first ignition
After the first ignition, with a cold burner:
–disconnect the pellet supply tube from the burner
–open the boiler door and check that on the combustion chamber grill THERE IS NO unburnt material. If this is not the case,
it is necessary to modify the settings on the basis of the specific needs (the combustion air and the quantity of fuel) and to
repeat the "FIRST IGNITION" phase previously described.
3.4 Automatic shut-down and subsequent start-ups
Once the request for heat has been satisfied, the pellet feeder stops, and the burner regulates its speed for the burning of
the residual pellet, present in the combustion chamber, up to the minimum luminance (20 lux) measured by the photocell.
When 20 lux is reached, the fan goes up to maximum velocity (for 4 minutes) to clean the combustion chamber of any resid-
ual matter and then it turns off.
At every request for heat all the phases described previously are repeated.
3.5 Pellet calibration
The calibration of the quantity of pellets necessary for ignition and for running the burner is achieved as follows:
–fill the pellet container
–pull out the flexible hose from the burner socket and place it in a recipient (basin)
–Check that there are no requests for heat
–Connect the burner power supply, positioning the plant main switch and the main burner switch in the "ON" position , and
check that the screen lights up
–press the button (manual loading) until the pellets are falling continuously into the recipient (the cochlea is full of pellets)
–empty the recipient and press the button again (manual loading) for about 6 seconds (loading time for max power 5),
controlling the time with a stopwatch, and weigh the pellets which have fallen into the basin.

15
Calculate the maximum burner power using the following formula:
Y*5/45*3,6= z (kW/h)
where
Y Quantity of pellets (in grams) weighed in 6 seconds (loading time for max power)
5 p.c.i. of the pellets
45 max. cochlea time
3,6 pellets in Kg/h.
m
WARNING CAUTION
If the type of pellets being used is changed (not advisable) the calibration of the pellets MUST be repeated, be-
cause the combustion characteristics will change.
3.6 Programming of user parameters
The programming of the user parameters can be done following the flow diagram above, after connecting the burner to the
mains.

4 MAINTENANCE
4.1 Periodic maintenance
Periodic maintenance, as well as being necessary for the optimal functioning of the burner and the plant, is required by Law
and if maintenance regulations are not observed, there can be problems or even fines.
Maintenance must be entrusted to and carried out SOLELY by qualified technicians.
The pellet burners B-Home Round 25 and B-Essential Round 50 have been designed to require minimal maintenance, the
frequency of which depends directly on the quality and the size of the pellets used (certified or not) and on how the burner
is regulated.
