Troubleshooting: Check the filling of the boiler furnace and
flue gas passes, chimney filling, and correct operation of the
pressure switch.
Possible cause: In safety time (12 min.) the flame did not
appear.
Boiler status: Currently goes to OFF mode.
Troubleshooting: Check that there is a pellet in the pellet
tank/transporter, if there are any foreign bodies in the
transportwer, that the flexible pellet delivery tube has a drop to
the burner so that the pellets can fall smoothly into the burner,
whether the burner grate is well placed in the burner (is not
installed ON the el. heater), whether the pellets are not too
humid, whether the pellets of the appropriate dimensions (for
these burner settings are 6 mm in diameter), whether the
burner blows hot air (whether the electric heater has blown),
whether the initial pellet supply is sufficient.
Possible cause: In safety time (12 min.) the flame did not
appear, and before that, the current disappeared in one of the
burner stages except "OFF", "A0" I S7-3.
Boiler status: Currently goes to OFF mode.
Troubleshooting: Check that there is a pellet in the pellet
tank, whether there is a pellet in the transporter, if the flexible
pellet tube has a drop in the burner so that pellets can fall
smoothly into the burner, that the flexible tube is not damaged
(blown or burnt) whether the burner grate is overcrowded with
the remains of burnt pellets, whether the burner grid is well
positioned in the burner (is not installed ON the el. heater),
whether the pellets are not too humid, whether the pellets are
of adequate dimensions (for these burner diameters 6 mm in
diameter) the burner grate is crammed with the remains of
burnt pellets, whether the burner blows hot air (whether the el.
heater has blown), whether the photocell is clean. Clean the
grate and burner.
