INSTALLATION
Handling of the product
Dunatech is a heavy product, and care should be taken when carrying the boiler to the room where it is going to be
installed. The total weight of each boiler is indicated in Technical data section. Carrying equipments of product must
be of enough capacity to support that weight.
Room selection
Dunatech boiler must be installed in an individual boiler room particularly organized for heating. The boiler room
should be of enough volume for installation, firing, and maintenance of the boiler. There should be enough fresh
air circulation for combustion, the chimney design must ensure an dequate draught for related boiler type, and must
comply with construction criteria given further in this manual and in mandatory regulations. Your boiler must never be
installed in open spaces or balconies, in spaces occupied by people like kitchen, living room, bathroom, bedroom, in
spaces where there are explosive and combustible materials.
The boiler room should have air ventillation holes through outside to let fresh air in. One air ventillation hole must be
built maximum 40 cm below the level of room ceiling, the other must be built maximum 50 cm above the floor level.
These ventillation holes should always be kept open. The upper hole should be at least 40x40 cm in size, the
lower hole at least 30x30 cm.
All hydraulic and electrical circuits must be arranged by authorized staff in accordance with mandatory regulations
specified by legal organizations.
Solid fuels should be stored by keeping minimum 800 mm distance from the boiler. We recommend you to keep the
solid fuel in another room.
Dunatech boiler should be installed on a concrete plinth made of a fireproof material. For minimum sizes of the plinth
following table should be referred

Clearances around boiler
At least the following clearances should be achieved around the boiler
Circulation pump
We recommend to build a forced water circulation system accompanied with a sufficient pump. To size the pump, refer
the boiler water side resistance level given in Technical data section, taking the other resistances created by the
hydraulic circuit into account. Refer to the system diagrams given further in this manual to find the right position of the
pump wtithin the hydraulic circuit.
Your boiler does not switch the pump on and off automatically. That is why, you should keep the pump
switched on, when the boiler temperature is above the cold water temperature or there is fuel firing inside
the combustion chamber. Never switch the pump off unless the fire is completely put off.

the combustion chamber. Never switch the pump off unless the fire is completely put off.
Never let the boiler water temperature reach high values sharply with leaving the pump switched off. In this
case, the instant cold water delivey to the very hot boiler may result in cracks on boiler body due to high
thermal energy.
