Astra P-7 USER MANUAL
Grasp the flame trap; pull it towards yourself until the lower part of the trap gets loose. Then, pull down it, remove the flame trap
from the chamber and clean. When done, work in the opposite sequence to place it back.
• FLUE CHANNELS CLEANING
The flue channels must be cleaned from combustion approximately once every three months. This period strongly depends upon
the quality of wood pellets. For this type of cleaning, it is recommended to consult with the technician who has installed the stove.
Use a drum-type vacuum cleaner only.
The flue of the stove has two channels: at the left and at the right side of the combustion chamber. These channels join together into
one smoke passage box near which the exhaust fan 16 (Fig. 1) is mounted. To access the inspection hatches of the flue channels, both
lateral panels and top cover of the stove must be removed. Before removing the top cover of the stove, the display has to be taken out
and disconnected. Work in the following order:
1. Remove the frame of the display. Using thin vertical screwdriver, locate two gaps in the left and the right side of the plastic frame
of the display. Turn the screwdriver inside those gaps, gently separate the frame from the display (Fig. 17a).

1. Protective handle; 2. Safety thermostat.
2. Take out the display. Use a PH1 size cross
screwdriver to unscrew four screws fastening the case
of the display. Lift the display (Fig. 17a).
The display is connected to the
controller board by RJ11 type data
cable. Do not forget to disconnect the cable
before taking out the display.
3. Remove the rooftop cover. Unscrew six M5 bolts
in the top rear side of the stove: three on the left
and three on the right side (Fig. 17b). Push the cover
towards the rear panel of the stove until its holders
get loose (Fig. 17). Then lift the cover and remove it.
4. Remove the lateral panels of the stove. Unscrew
bolts fastening the panels near the front grates at the
top part of the stove (Fig. 18a) and in the front and
the rear sides of the base plate of the stove. Raise the
panels and remove them (Fig. 18).
5. Open all four the inspection hatches. Unscrew
pairs of M5 bolts, remove gaskets and inspection lids
(Fig. 18b). Clean the flue channels in both sides of the
stove.
• PELLET HOPPER PROTECTION
AGAINST BURNING
The pellet hopper has a protection from overheating
and burning: the temperature sensor 6 and the
thermostat 12 (Fig.1). They operate independently
from the controller. If for any reason the hopper
starts overheating the thermostat stops the stove by
interrupting the electrical supply.
To restart operation of the stove, remove the
thermostat cover 2 (Fig. 19) and depress the button
behind it.
