Pellet retarder - feeder pipe
When the pellets are extremly hard
and/or the hose to the feeder pipe is
unusually long the pellets occationally
fall out of the burner. To prevent this
you could mount the pellet retarder.
Unscrew the screw in the front of the
feeder pipe. The pellet retarder mounts
with a screw from the outside.
(RXS 4,2 x 9,5).
The local chimney sweep sweeps the chimney once or twice a year – this is usually
notified at least a week beforehand. Ensure that the burner is switched off in good
time prior to the visit so that the burner and boiler have time to cool down.
Safety systems
The PX22 stoker meets all current safety regulations and standards.
There are two separate safety systems to avoid fire and hot gases going backwards:
a slooping stainless steel tube for the pellet feeder, and a cut-out thermostat on the
tube. These safety systems are independent of the electronic control system and
therefore cannot be disturbed by outer causes as for instance lightning.
A third safety component is the flame sensor, which indicates whether the fuel level
in the burner rises to a non-permitted level, or if cleaning is not carried out and the
burner pipe has too high a level of residual products.
In this case, the display shows in which operating mode the flame stopped being
indicated and stops as follows:
ErrStart
- Operational stoppage at ignition.
ErrLow
- Operational stoppage in low output mode.
ErrHigh
- Operational stoppage in high output mode.
GOutStrt - Flame indicated at ignition but not in operation.
Resetting cut-out thermostat
The burner has overheat protection on the fall pipe, which deploys at 75˚C.
If it deploys, Errsafe appears in the display.
1. Disconnect the cords from the burner.
2. Unscrew the two screws from the cut-out thermostat protective cover,
remove
cover.
3. Push botton on cut-out thermostat until it clicks.
4. Reassemble the protective cover.
Maintenance
The stoker is cleaned by raking out the ashes inside, wich
must be done once a
week during the cold season
. Otherwise a cleaning every other week is sufficient.
At these occasions the boiler also should be rinsed from ashes.
Ashes and soot inside the boiler can set back the efficiency dramatically.
Note!
If the boiler previously has been fired with wood there’s a risk of soot and
taar getting loose and choke up the flue pipes and even the chimney. Check and
rinse if needed when rinsing the stoker for the first two months after installation.
The burner must be dismantled at least four times per year.
The outer and inner burner tubes should be separated and cleaned from sintered
ashes. Dismantle by loosing four screws on the front of the stoker.
Note that all cables have to be unplugged before removing the cover.
