Astra P-8 USER MANUAL

Before starting cleaning works, make sure that:

•   The electrical supply switch on the rear panel of the stove is OFF;

•   All stove components and ashes have cooled down sufficiently;

•   Suitable tools will be used for cleaning;

•   The electrical cable is unplugged when flue channels are to be cleaned.

When cleaning the combustion chamber, be careful and do not clog the pressure sensor’s pipe which 

is mounted inside, on the left wall of the chamber, under a vermiculite plate. The pipe must remain 

unobstructed.

The frequency of maintenance and cleaning depends directly on the quality of pellets used. Burning high quality pellets allows you 

to devote less time and attention to cleaning activities, and to increase the periods between cleanings. Vice versa, bad quality pellets 
will require shorter intervals between cleaning tasks. The quality of the pellets and a sound adjustment of combustion are essential 
to the reliable operation of the stove.

The pellet stove is a generator of heat and technically 

sophisticated appliance. Therefore, we strongly recommend 
servicing by qualified personnel at least once a year, at 
the start of the heating season to ascertain and ensure 
the continued function and efficiency of all the stove's 
components.

• EXTERIOR SURFACES CLEANING

To clean the surfaces on the painted metal parts, use a cloth 

slightly moistened in water. If necessary, mild soap may also 
be used. Rub the surfaces gently and with care.

Do not use any aggressive detergents or 

solvents – they can cause serious damage to 

the surfaces of the stove. Do not scrub excessively the 

metal paint - the structured paint surface changes its 

shading because of rubbing impact.

• HEAT EXCHANGER TUBES CLEANING

The heat exchanger is composed of stainless steel tubes. 

Smoke flows constantly around the outer surface of the 
tubes leaving soot residues on them. These residues must be 
removed every 2 days of operation. For this purpose, inside 
the heat exchanger there is a scraper which brushes the 
tubes' surfaces like a comb. Pull the handle of the scraper 1 
( Fig. 12) towards yourself. To complete the cleaning session, 
push and pull this handle till halting several times. 

• ASHES DRAWER CLEANING

The ashes drawer must be cleaned daily or every 2 days, 

depending on the length of time the stove is used and the quality 
of pellets used. To access the ashes drawer, open the door, remove 
the ashes drawer 4 (Fig. 12) and empty it.

•COMBUSTION CHAMBER CLEANING

Clean the combustion chamber every 2 days. Use a drum-type 

vacuum cleaner for cleaning the combustion chamber. Make sure 
that no ashes are left after the cleaning session.
