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.

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 
firing. 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 cm

2

, 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 inflow from 

outside. The stove can consume up to 40 m

3

 of air per hour at maximum, so the sufficient 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 flooring is present in the desired place of installation, first cover it with a protective fire-resistant plate made from steel, 

glass or ceramic;

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

3

 of volume;

• Make sure that a floor base on the place of installation has a sufficient 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, fireplace) without autonomous air supply is present in the room of considered placement of the 

Astra stove, evaluate, whether there would be a sufficient 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 qualified personnel. 

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