6. Make sure that the end of burners feeder auger tube and rear wall of the burning chamber were in one
level and brackets (1) would enter freely to its nests. If not so, turn the power screw of linear motor
clockwise and try again. Make sure when connecting burners housing with burning chamber that fast
connection joint of linear motor and grate moving bar are connected i.e. stud on motor side and the slash
on power screw are in one line and connected.
7. Remount both grades in right order and right directions. Make sure that lower grade is connected to
linear motor rod’s power screw and fixing slots of upper grade are placed onto fixating studs in back side
burning chamber.

External auger
The external auger transports pellets from the pellet container to the burner. The burner controls the
work of the external auger. The external auger is connected to the burner with a special
∅
60mm hose.
The hose is made of melting polyurethane material and acts as a safety measure against back-burning.
External auger can be fixed to a ceiling or container depending on conditions at the site. Figure 12 shows
correct placement for external auger.
External auger must be installed as described below:
Hang auger to ceiling or fixate it to the boiler in the way mentioned below.
Install hose between auger and burner. Fixate hose with 2 brackets from both ends.
Connect auger’s cable to burner. Make sure that plug is surely connected with socket.
Make sure that:
The vertical distance between the output of external auger and burner is 400 – 700 mm.
The horizontal distance between the output of external auger and burner is 100 – 200 mm. It ensures
that the hose will melt incase of back-burning.
The raising angle of the auger doesn’t exceed 45° to ground, otherwise the auger doesn’t manage to
transport enough pellets.
In order pellets can fall freely into burner, the falling angle must be between 50° and 85°.
Plug of the external auger is surely connected with burner’s socket.
Igniter
Caution!
Make sure, that after mounting the
igniter’s end tip was at same level with the
burner’s rear wall and don’t reach out or hasn’t
got stuck behind the rearward wall Figure 11.
