Page 4: Installation
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. - Page 5 Hydraulic circuit Open vented hydraulic circuit Dunatech boilers are preferred to be installed in a hydraulic circuit with an open type expansion tank in accordance with the following schemes. The circulation pump in the circuit should be installed on the return line to boiler in order to prevent the system from excessive thermal stresses and overheating during electricty cuts off: Open type expansion tank must be installed at the heighest level of whole hydraulic system.
- Page 6 Design parameters for open expansion tank Expansion tank protects the hydraulic curcuit from excessive temperatures by allowing free volume for expanding water and keeping the water pressure from exceeding the static pressure. Expansion tank may be built in rectangular prism or cylindirical shape, may be installed in horizontal or vertical position in the system. Safety lines between boiler and expansion tank should be installed by an increasing slope up to tank.
- Page 7 Pressurised hydraulic circuit Dunatech boiler can be installed in a pressurised heating system if following scheme is referred with addition of the safety heat exchanger kit which is supplied as a separate accessory. maximum pressure: 3 bar p essu e 3 ba Safety heat exchanger includes the following items: 1.
- Page 8 Chimney connection Dunatech boiler must be connected to an individual chimney that will provide at least the minimum draught requested. The flue canal between the boiler and the chimney should be insulated using a glass wool material. The flue canal to chimney and chimney must be made of steel or an equivalent material that can be used at temperatures around 400 C All connections on the flue system must be sealed in order to perform a good combustion and efficiency.
- Page 9 ASSEMBLY INSTRUCTIONS Numbers between paranthesis refer to bubble numbers in exploded drawing of the boiler that can be found at the end of this manual Dunatech boiler should be installed on a concrete plinth made of a fireproof material. We recommend you to place two pieces of steel sheetmetals underneath the front and rear elements of the boiler preferably with the dimensions H: 3 mm x L: 500 mm x D: 200 mm.
- Page 10 6. Likewise, fit the right hand side panel (39). When you work at the front side of the boiler, loose three M8 nuts (G) that are used to secure front door hinges (28, 29) a little, drive the front bend of the panel through the free space behind A8.4 flat washer (F).
- Page 12 13. by fixing the rear casing follow the instructions: ― Fit the rear panels as it is seen in the pictures. ― Finally fit the damper onto the rod. please see the following pictures.
- Page 13 Safety heat exchanger (optional) The safety heat exchanger is used to save the boiler in case of overheating. In case of electrical cutout, pump defect etc. the boiler water temperature can be overheated. If the boiler water temperature exceeds 95 ºC, thermostat of the safety valve lets cold sanitary water flows through the serpantine of the safety heat exchanger.
- Page 14 1. Remove the existing outlet stub pipe with flange of the boiler 2. Install the safety heat exchanger to the delivery port on the rear section by four pieces M10X25 bolts. Use gasket supplied with safety heat exchanger to provide sealing. 3.
- Page 15 OPERATING INSTRUCTIONS Setting the thermo-regulator (thermostatic controller for combustion air) Mechanic type thermo-regulator is mounted on top of front section in vertical position. In vertical operation of thermo- regulator, red coloured numbers show the requested heating temperatures. After assembly of thermo-regulator body, place the lifting rod for regulator.
- Page 16 Firing with hard coal and coke *If you fire hard coal or coke, we recommend you to keep secondary air damper fully open. If your chimney is built enough to ensure an adeqaute draught, you can keep secondary air damper 1/2 closed. *Flue damper on the smokehood should be kept fully open or 2/3 open.
- Page 17 Care should be taken when handling sheet metal panels that do not have safety or folded edges Lifting cast iron sections Care should be taken when lifting cast iron sections as they can weigth up to a few hundred kilograms and ADARAD can confirm the weight of each individual section if required...

Page 19: Maintenance And Cleaning
MAINTENANCE AND CLEANING Regular maintenance by qualified staff, strictly in accordance with the manufacturers instructions is essential for the efficient operation of system. Periodic inspections * Check the water level or pressure either in open vented or pressurised systems. The hydrometer must be marked after first filling of the boiler. -
