Mounting of the burner
1. Decide where on the boiler the burner should be mounted. If possible place it so that you can open the
door with the burner still on, since that facilitates the operation.
N.B.! THE DOOR MAY NOT BE POSSIBLE TO OPEN WITHOUT THAT THE POWER TO THE BURNER IS
SWITCHED OFF.
2. Mark out where the burner shall be placed and make a hole in the door, with for example a compass saw
for metal. Mount the docking flange and pack with fireproof insulating mat or high temperature silicone, we do
not recommend boiler cement. The sleeve coupling shall be mounted with the screw on the right side. Insert
the burner and direct it up straight and tighten the screw. If possible, we recommend that you mount a
fireproof board on the inside of the door that for example is fastened with a sheet-metal of approx. 1-2 mm in
stainless. This makes you avoid radiant heat backwards towards the burner. See picture example to the right.
3. Make sure that all doors and dampers are packed, so that air can not enter. This is a disadvantage since it
makes it more difficult to adjust the burner to optimal combustion since it is then leading to too high surplus of
oxygen in the combustion and in turn a worse efficiency.
4. When the burner is mounted and possible packing of the boiler is made, the auger should be mounted.
Fasten the auger with the enclosed chain in the ceiling. Before the auger and the burner are mounted
together, see the start and settings chapter. IMPORTANT! IF FLUE-GAS DAMPER EXISTS IT SHOULD
ALWAYS BE OPEN. ALL DOORS AND FLUE-GAS CONNECTIONS SHALL BE PACKED. This is extra
important if the chimney is narrow or generates bad draft for another reason. Otherwise there is a risk for
indention at start, especially if the burner is not correctly set.
The angle from the horizontal level shall be between 42 and 45 degrees. The feed auger has to be fastened
well since it wants to work its way into the storage. The auger is hanged up in the front edge with the
enclosed chain and fastened well in the ceiling. The feed auger should be placed so that it does not sit right
above the tipping chute on the burner. This only to avoid that pellets can fall down into the tipping chute if
back fire would appear and the hose burns off as part of the safety. The auger shall be removed from the
storage at least once per year and be cleaned from chip wastes. Then re-mount the auger and connect the
connection cable of the auger with the net cable of the burner and run it manually until pellets have been fed
out from the auger in about 15 minutes. This to avoid air pockets that could cause uneven feeding. Also
control the angle of the auger again. We recommend that you run the auger a couple of times manually for 60
seconds intervals and then weight each dose to see if the auger gives an even feeding. The margin of error
should only be within 3-4 %. The screw must give in 60 seconds about 125 g.
