1. Boiler use and advantages

A single-row cast-iron sectional hot-water boiler with an overpressure combustion chamber and a

direct firing designed for gas (natural gas) and fluid fuels ( furnace oil extra light ) central heating . The

pressure burners used in combination with boiler must correspond to:

ČSN EN 676: 2000 – Gaseous fuels burners with a ventilator and an automatic control

ČSN EN 267: 2000 – Fluid fuels burners wit a ventilator

ČSN EN 303-1:1999 – Boiler pro central heating with burners + ventilator

ČSN EN 303-2:1999 – Boiler pro central heating burners + ventilator

ČSN EN 303-3:1999 – Boiler pro central heating burners + ventilator

The boiler is produced exclusively for low-pressure hot-water central heating systems with

maximum 90 °C heating water operating temperature (optionally up to 115°C), minimum 60°C heating water

operating temperature at maximum 4 bar operating overpressure .

The boiler drum is tested by 8 bar testing overpressure.

Boiler advantages are as follows:

1. Longstanding service life of cast-iron boiler drum

2. Highly economical operation. Combustion efficiency in the whole power series is higher than 91,5 % for all

sorts of fuel

3. Optionally a delivery incl. the burner

4. Modern design

5. Fully automatic two-stage operation

6. Boiler operation and defects signalling, possibly use of signals for transfer into a superior control system

7. Possibility to operate boiler through the superior automatics or a spatial temperature sensor

8. According to the boiler layout the closing plate can either open to the left-or the right hand side

9. Easily accessible sight glass and the probe for overpressure measuring in combustion chamber.

10. In combination with recommended burners (see chapter “Boiler technical parameters”) this boiler is

environmentally friendly because the whole power series combustion results meet the strict environmental

standards and regulations.

The gas flow is specified at the gas temperature and 0 °C and 1013,25 mbar air pressure For a particular

temperature and pressure the real consumption is calculated as follows :

1013,25 . (273 + t)

V = VE . ----------------------------------------

p . 273

V - gas volume at a given pressure and temperature

VE - gas volume at 0°C and 1013,25 mbar

t - gas temperature (°C)

p - absolute gas pressure (mbar)

3. Description

3.1.Boiler construction

The boiler drum (see Fig. no. 1 – individual positions) consists of sections by means of forced on

insertions and secured by anchor bolts. The boiler has three-draught construction and the combustion chamber

and the convective part are created by sections; the boiler water space is inside. The boiler tightness is

guaranteed by the packing cord inserted in a groove on four sides of individual sections and the combustion

chamber plus the silicon sealant deposited in grooves at the point of sections joint after boiler drum constriction.

On the frontal section is there is mounted closing plate with insulation which can open either to the left

or to the right hand side. This must correspond with hinges and closures position. The flange for burner is a part

of closing plate. On the flange there is placed a sight glass with a probe for measuring the overpressure in

combustion chamber.

The opening φ126 mm in the upper part of the frontal section is closed by a flange with boring 3 x G 1/2“ for

the reservoir of thermostat, safety thermostat and thermometer and the reverse valve of manometer. In the

lower part of the frontal section there is an opening φ126 closed by a blank flange.

Input and output of heat carrier are situated on the rear section and is carried out by means of flanges with

a sleeve DN 100 and intermediate flanges DN 100. On the lower sleeve there is the discharge cock G 3/4“.

The restricting insertion belongs to the flange with the sleeve for heat carrier input. In the riser above the lower

flange with a sleeve there is positioned the outside protective clamp of boiler. In the upper and lower parts of

the rear section there are four small covers for cleaning.

Flue gases are carried away from boiler through the outlet neck positioned on the flue collector. Under the

outlet neck there is the explosive flap with a holder. On the outlet neck there are the measurement points for

temperature and flue gases analysis. .

The boiler drum is perfectly insulated by the mineral wool plates 100 mm thick. The steel shell of boiler

is suspended on two consoles of the shell positioned next to upper anchor bolts. The surface is treated by

comaxit paint. In the frontal part of boiler there is installed the electric panel in which there are installed the

switching, regulation and safety elements and the wiring block.
