3.0. OPENING FOR FRESH AIR (FRESH AIR SUPPLY)

Each boiler room must be equipped with an opening for supply of fresh air which is dimensioned

in accordance with boiler output (minimum opening area according to the below shown equation).

Such opening must be protected with a net or grate. All installation works have to be performed in

accordance with valid national and European standards. Boiler must not operate in flammable and

explosive environment.

4.0. CONNECTION TO CHIMNEY

Properly dimensioned and built chimney is a precondition for safe boiler operation and heating

efficiency. A chimney must be thermally insulated, gas-tight and smooth. Cleaning door must be

made in the lower part of a chimney. Chimney made of bricks must include 3 layers with central

insulation layer made of mineral wool. Thickness of thermal insulation should be min. 30 mm of

chimneys is built against to interior wall, and min. 50 mm if it is built on the outer side. Internal

dimensions of the chimney light diameter depend on chimney height and boiler output and

they have to be selected in accordance with diagram shown in Figure 3. The chimney usable

height is the measure from connection spot of smoke pipe to the chimney top. As these boilers can

be fired with wooden pellets at any time, chimney has to be selected according to the wooden

pellets diagram. Fuel gas temperature at the chimney exist must be min. 30°C higher than

condensation temperature of combustion gases. Selection and building of a chimney must be

made by a professional. Required maximum distance from boiler to chimney is 600 mm, and

minimum distance is 300 mm. Uptake tube must be installed at an angle (min. 5°) with a gradient

from chimney to boiler (Figure 2). In order to prevent condensate from chimney to enter the boiler,

uptake tube must be placed 10 mm deeper into chimney. Connecting uptake tube between boiler

and chimney must be thermally insulated with a mineral wool layer having thickness of 30 to 50

mm.

All installation works must be made in accordance with valid national and European standards.
