2. INTENDED USE

The Astra pellet stove is an eective home heating appliance intended to heat a room with hot blown air. It simultaneously performs

the function of a replace as you view the re through the temperature-resistant glass. It can be installed in all kinds of residential spaces

where people work, relax or spend their time. In order to reduce any possible danger to human health and property, the stove Astra is

equipped with special safety devices. For added convenience, control of the appliance can be fully automated. Once programmed, the

Astra pellet stove is capable of maintaining dierent heating output levels at a variety of pre-set time intervals over the course of a day,

seven days a week; it sustains a set air temperature in the room with the help of an integrated temperature sensor; and it even makes the

Astra P-8 USER MANUAL

decision to stop the appliance if unfavourable safety conditions arise: draught of the ue disappears or has fallen substantially, the door

of the stove is opened during the operation; the pellet hopper heats up; or other potentially harmful events happen. In addition, the stove

can be operated by a remote control unit (available by special order).

Only 6 mm wood pellets are used for fuelling the Astra stove. The appliance is not designed to be operated with any other kind of fuel

because other fuels leave a greater content of ashes and slag.The latter then will cause the re pot to clog, activating emergency stop of

the appliance. In order to enjoy the pleasant heat of the stove without unpleasant interruptions, use only high-quality 6 mm wood pellets

and keep the combustion chamber, re pot and ue channels of the stove cleaned at all times.

3. TECHNICAL DESCRIPTION

• COMPONENTS OF THE STOVE

Wood pellets from the hopper 4 are transported by means of the auger 5 into the re pot 19 (Fig. 1).The electrical igniter 18 kindles

the pellets. The ame and hot ue gases rise to stainless steel heat exchanger 1, descend afterwards by two lateral ue channels

surrounding the combustion chamber and are released with help of exhaust fan 16 into the chimney connection pipe 13. The room

ventilator 7 draws air from surroundings and blows it through the hot heat exchanger tubes 1, thus supplying heat.

4. FUEL

Use 6 mm diameter high quality pellets to fuel a stove. When purchasing pellets, make sure that they comply with one of the bellow

listed standards and their packing is marked correspondingly:

EN 14961-2, class A1,

ENplius-A1,

DinPlius.

Wood pellets of lower quality could also be used for fueling but the stove‘s operation in that case will not be stable because of the

fuel quality. Do not use the non-wood pellets for fueling the stove.

Parameters of pellets according to EN14961 standard, class A1:

Length 3.15-40 mm

Diameter D06 6 +/-1 mm

Weight BD600 > 600 kg/m3

Caloric value Q4.6 > 4.6 kWh/kg

Residual humidity M10 < 10 %

Ashes content A0.7 < 0.7 %

Fines content F1.0 < 1 %

Do not put a bag of pellets on the surface

of the stove during the loading operations!

The pellets must be transported and stored in a dry place. They

swell after contact with moisture and become unsuitable for

ring. The pellets must always be protected against humidity

both during transportation and storage.

Astra strongly advices using the 6 mm diameter

wood pellets for fuelling the Astra stove.

5. PLACEMENT, ASSEMBLY AND INSTALLATION

•CONSIDERATIONS FOR PLACEMENT OF THE STOVE

The residential space considered for the placement of the stove must meet the following technical requirements:

• Pipe connection to a chimney of 8 cm diameter must be installed;

• The supply of air for combustion must be assured either from other ventilated rooms through opening of at least 100 cm2, or directly

from outside through the 35 mm air intake pipe. The design of grilles mounted on the opening shall exclude blocking of the air

supply;

• The permanent humidity of air in the room must not exceed 80%;

• A connection of electrical supply of 230V, 50 Hz must be installed;

• CE compliant earthing system must be present.

The placement of the stove is important for the successful heating of the room. Please, take into account the next considerations

before deciding where to place the stove:

• If the supply air needed for combustion is to be taken from another room, that room must be ventilated or have air inow from

outside. The stove can consume up to 40 m3of air per hour at maximum, so the sucient amount of it must be supplied either from

outside or from another inner space of a house;

• The stove cannot be placed in the bathroom, near a shower or bath, or in another space with high humidity level;

• If wooden ooring is present in the desired place of installation, rst cover it with a protective re-resistant plate made from steel,

glass or ceramic;

• The room in which the stove is to be placed must have at least 30 m3of volume;

• Make sure that a oor base on the place of installation has a sucient holding capacity to bear weight of the stove;

• It is recommended to place the stove in the largest room of a house or in a room which has good connectivity with other inner spaces

of a house, so that the maximum circulation of heat would be ensured;

• Connection to the electrical supply must be done through a grounded socket. If the cable of the stove is not long enough to reach the

nearest socket, use a grounded extension cable;

• If another heating installation (stove, replace) without autonomous air supply is present in the room of considered placement of the

Astra stove, evaluate, whether there would be a sucient air supply for both appliances working simultaneously and if that kind of

double installation is allowed by local technical regulations;

The stove must be installed and assembled only by qualied personnel.

• The stove must be placed so that easy access to it and to a chimney is ensured.

Astra P-8 USER MANUAL

• The joints of chimney pipes must have temperature resistant gaskets in order to ensure sucient tightness of the connections;

• A separate chimney is mandatory for the Astra stove installation. It is not permitted to connect the stove to a shared ue;

• The connection of the air intake tube of the stove to an outside is not obligatory. If the air for combustion is taken from inner spaces

of the house, these must be ventilated so that up to 40 m3of air inow is ensured;

• Do not use a mesh on the top of a chimney because it can reduce draught and cause problems for the stove functioning;

• When designing the chimney piping for the stove, do not use more than 3 pieces of 90° bends. The biggest distance between the

adjacent bends must not exceed 2,5 meters horizontally;

• A minimum distance of 10 cm should be left from the rear stove panel to the wall. A 20 cm free space must be left from lateral sides

of the stove and 150 cm- from the front side.

• PATTERNS OF INSTALLATION

A 90° bend should not be installed as the rst

connecting part – ashes would quickly obstruct a

passage for smoke causing unexpected problems

for draught of the ue (Fig 4).

This type of installation (Fig. 3) requires an

insulated ue, as the whole smoke pipe is

installed outside the house. A chimney tee with

an inspection cap and condensate drain pipe is

mounted in the lower part of the ue.

This type of installation (Fig. 5) does not require

an insulated ue as the smoke pipe is assembled

partly inside the house and partly inside an

existing ue. A chimney tee with a peephole cap

is installed in the lower part of the ue.

Please note the use of two 45° bends in order

to guarantee that ash falls into the chimney tee

with the cap and the peephole.

This type of installation (Fig. 6), does not require

an insulated ue, because the whole smoke pipe

is assembled inside a house. A chimney tee with a

peephole is mounted in the lower part of the ue.
