1. INSTALLATION AND CHIMNEY PARAMETERS

By installation of chimney connection to boiler it is necessary to care about correct outlet of flue

gas and eventual condensate, not to let it fall back into the boiler. For this purpose you can use

the T-piece, see picture below. Exhaust connection comes into the chimney vent. If it is not

possible to connect boiler to chimney vent directly, then the adequate extension of exhaust

connection has to be as short as possible, and no longer than 1 m, without additional heating

surface and it has to go up in direction to the chimney. Exhaust connections must not go

through foreign dwelling or utility units. Internal cross-section of the exhaust connection must

not taper in direction to the chimney. Try to minimize usage of elbows by installation. Chimney

has to be constructed in conformity with the norms STN 73 4201 and STN 73 4210.

Prescribed values of the correct height and

cross-section chimney dimensions:

DPX15, DPX25, DPX35, DPX45

20×20 cm min height 7 m

20 cm min. height 8 m

15×15 cm min height 11 m

16 cm min height 12 m

2. VERIFICATION OF THE CORRECT CHIMNEY PARAMETERS

Correct boiler function significantly depends on quality chimney with correct parameters.

Minimum chimney diameter is 150 mm, however, 200 mm is recommended. Chimney has to be

designed or regulated to achieve prescribed draught of 23–30 Pa at nominal boiler flue gas

temperature value.

ATTENTION! Chimney which does not fulfil required parameters may cause limited

boiler function (Low flue gas temperature, low output, excessive condensation of

tubular exchanger, shorter life-time, even total boiler disfunction)! Guarantee does

not relate to the boiler installed with the chimney of incorrect parameters.

3. DEVICES FOR CHIMNEY DRAUGHT MEASURING

It is possible to check correct chimney draught by some types of analysers or by exact

differential pressure-gauge. On the picture there is draught reducer too, also useful for correct

draught setting.

4. OPERATION PRESSURE IN HYDRAULIC CIRCUIT

Operation pressure must not exceed limit of 2,5 bar.

ATTENTION! Expanse vessel and safety valve must be installed in the system.

5. BOILER PROTECTION AGAINST EXCESSIVE

CONDENSATION – ATTACK-OVENTROP

For correct boiler function and its long life-time it is necessary to keep return water temperature

always higher than 65 °C. Set boiler thermostat to 80-85 °C, which is ideal boiler operation

temperature. Boiler guarantee is valid only in case that the ATTACK-OVENTROP device was

installed into the hydraulic system.

ATTENTION! If the ATTACK OVENTROP device is not installed, it may cause shorter

boiler life-time.

6. CORRECT ASHTRAYS POSITION

Ashtray position is important for correct boiler operation. It is not necessary to take out the

ashtray while cleaning, but it is important to check its correct position sometimes. Ashtray has to

be completely shifted rearwards.

7. FUEL

Use suitable fuel for wood gasifying boiler operation – soft or hard wood logs. Wood moisture

has to be in range of 12–20 % (related to time of min. 15 month of free storing at the fresh air).

Alternatively it is possible to use wood briquets of cylindrical shape with opening in the middle.

ATTENTION! Wood with moisture exceeding 20 % shortens boiler life-time, causes

lower output, excessive condensation in tubular boiler exchanger, which may

require additional out-of-warranty service!

8. AFTERCOOLING CIRCUIT INSTALLATION

Boiler warranty is valid only in case, that functional thermostatic valve, connected to the cold

water source, is installed in the boiler aftercooling circuit. If the cold water source depends on

electricity (home water plant), whole device can be out of order in case of power failure. In this

cases, use water tanks placed higher than boiler, connected to thermostatic valve. Tank volume

has to be appropriate to the boiler outuput.

ATTENTION! If there is no aftercooling circuit on the boiler and it comes to boiler

overheating, serious and non-recurring damage or even fire may occure.

9. CORRECT ADJUSTMENT OF AIR INLETS

Correct adjustment of primary and secondary air by STANDARD and PROFI boilers is marked on

tin-plate and it is not necessary to manipulate with that. Correct setting of primary air (upper

butterfly) is 100 %, secondary air (bottom butterfly) is set to 35 %. This relates to all outputs of

DPX boilers (15, 25, 35, 45).

10. ASHTRAY CLEANING

Internal space of ashtray has to be cleaned from accumulated ash at least 1× a day. Cleaning

with scoop is very effective and easy. Cleaning can be done very easily and fast also by full boiler

operation.

ATTENTION! Hot ash from ashtray can still smoulder, therefore it is not supposed to

be put into trash bin, however into appropriate tin-plate bin, not to cause the fire.
