Fig. Dimensions of the elevated step.

location of the boiler to keep necessary manipulation space:

- Basic space AA5/AB5

- In front of the boiler there must be manipulation space of min. 800 mm

- minimum distance between the rear part of the boiler and the wall must be 800 mm

- at least form one lateral side keep space for approach to the rear part of the boiler - min. 800 mm

Location of fuels:

- to put fuels behind the boiler or keep them near the boiler in the distance shorter than 800 mm is not allowed

- to put fuels between two boilers in a boler room is not allowed

- it is recommended bez the manufacturer to keep the distance of min. 800 mm between the boiler and fuels, or to locate fuels

in a room other than where the boiler is installed

Requirements for the boiler room

Chceck that the room has the requirements in accordance to the rules. Furthermore, the room should be aired in order to have a

regular combustion. Therefore it is necessary to practice some openings in the wallls of the room, which correspond to the

following requirements:

- They should have a free section of at least 6 cm for each 1,163 kW (1000 kcal/h). The minimum opening section shouldn´t be

smaller than 100 cm . The section can also be calculated using the following ratio:

- where "S" is expressed in cm

- "Q" is expressed in kcal/h

S =

100

-The opening should be situated in the lower part of an outer wall, preferably opposite the combustion

gas discharge.

Connection to the flue

A flue should correspond to the following parameters::

it should be of waterproof materials,resistant to temperature of smokes and condensations

it should be of sufficient mechanical resistance and a weak thermal conductivity

It should be hermetic in order to avoid cooling of the flue

it should have the most possible vertical process and the terminal part should have a static aspirator, which assures an

efficient and constant discharge of the combustion product

in order to avoid the wind creating and a high pressure around the chimneypot, so that it prevails on the ascensional

force of the combustion gas, it is necessary that the discharge orifice hangs over at least 0,4 m of whatever structure

adjacent (including the roof ridge) and the height of the chimney itself was at least 8 meters.

The flue shouldn´t have a diameter inferior to the boiler connection.For flues with square or rectangular sections, the

internal section should be higher than 10% compared to the boiler connection section.

The net section of the flue can be obtained from the following ratio:

S = K

2. Safe distance from combustibles

- during the installation as well as during the operation of the boiler it is necessary

to keep the safe distance from combustibles

- for easy combustible substances of combustibilitz level C, that burn quickly and

go on beurning even after removing the source (e.g.. paper, cardboard,asphalt

cardboard, tar paper, wood and wood-fibre boards, palstics, floor coverings), the

safe distance is doubled

- It is also necessary to double the safe distance in the case when the

combustibility level is not known

S - section in cm

k - reduction coefficient

P - boiler capacity in kcal/h

H - height of the chimney in meters measured from the flame axis at the exhaust of

the chimney in the atmosphere. For the dimensioning of the flue you should

consider the effective height of the chimney in meters measured from the flame axis

to the top, adminished in:

- 0,50 m for each direction changing of the connection tube between boiler and flue,

-1 m for each horizontal meter of the connection itself.

- 0,045 for wood

- 0,030 for carbon
