Biopel MINI - Installation and Operation Instructions

6.2.
Burner
The burner type and size always depends on the size of the Biopel MINI boiler. Therefore, installing the burner varies
according to burner and boiler size. The entire installation can be summarised in the main points below:
1.
Unpack all the burner parts in the box.
2.
Install the burner flange on the burner opening on the boiler, if included. Flange type varies according to the burner
size, therefore the flange installation method on the boiler varies.
3.
Attach the burner on the 2 burner bolts (installed on the flange or on the burner opening on the boiler) and tighten
with 2 wing nuts and 2 washers. The joint must be as tight as possible. Push on the burner several times during
tightening to ensure that the burner is firmly attached and that it does not move in any direction.
4.
Done. The burner is installed in position. If you mover the Compact or External Hopper during burner installation,
place it back in its final position.
The next step is to install the External Pellet Feeder, if you used the External Pellet Hopper, then connect the feeder to
the burner. Follow the steps below.
6.3.
External feeder
The external feeder installation is only done in combination with the external pellet hopper. If this is your case, please
follow the points below. If you have used the compact version of the hopper, skip to the next paragraph regarding the
connection of the external feeder to the burner.
1.
Remove the paper cover from the top of the external feeder.
2.
Make sure that no parts of the feeder have been damaged during handling. Check the bottom of the feeder where
the worm shaft exits the PVC tube to the outside. The hole at the end of the PVC tube must not be deformed in
any way. The edges of the tube opening must be horizontal with the tube body, not curved inwards (towards the
worm shaft). If this were the case, there would be a risk of the worm shaft getting stuck on the opening of the PVC
tube and possibly jamming the feeder.
3.
Rotate the external hopper's bottom leg so that the opening in the hopper faces towards the boiler.
4.
Slide the bottom end of the external feeder into the hole in the hopper leg. The hole in the bottom of the external
feeder must be entirely inside the bottom leg of the external hopper's bottom leg.
5.
Using the chain and hook (included with the external hopper), hang the top of the external hopper by the top edge
of the external hopper or by the holes in the top of the external hopper legs.
6.
Adjust the chain so that the external feeder is at an angle of approximately 45° from the ground. If the angle is
smaller, the feeder gives more pellets than the standard, if the angle is larger, the feeder gives less pellets than
the standard. If the angle is different, a combustion correction will be necessary, see chapter Combustion
Correction.
The feeder must be at a 45° angle to the ground for proper fuel feeding. If not, make
adequate combustion correction, see Combustion Correction chapter.
The external feeder is placed. Connect it to the burner. This connection is made for both the external and compact versions
of the hopper. Please follow the steps below:
1.
Place the burner pipe inside the hole in the top of the burner. DO not forget to use the sealing ring.
2.
Secure the burner pipe with 3 black screws.
3.
Connect external feeder outlet and burner pipe with PVC hose. Caution: The PVC hose must not be slack to avoid
pellets becoming stuck. The pellets must fall inside the PVC hose without jamming on the way to the burner. Check
the correct installation of the PVC hose during boiler operation!
