Wood stove furnace Prity NS32, 36.4kW

The boiler is designed to be placed in a ground floor room or a basement where it's easy to load wood and wood briquettes.

Its purpose is to heat water for local central heating systems, as well as heating domestic hot water.

Main characteristics of the wood burning boiler:

• Body made of 2mm thick sheet steel
• Top made of 3-4mm thick sheet steel
• The main part of the boiler is the heat exchanger. It's constructed from welded sheet metal. The lower part is the burning chamber.
• The ash drawer is placed below the burning chamber. It collects the residue from the burning process and allows easy maintenance and cleaning of the unit.
• The cold water inlet is placed on top, and the hot water outlet - on the back. Both of them are threaded and are used to connect the boiler to the central heating system.
• The chimney pipe is on the upper part of the boiler and is used to lead off the flue gases.
• The steel heat exchanger has rock wool insulation which reduces heat losses to the environment.
• The external decorative sides are constructed from sheet metal and are powder coated.
• A manual damper is placed on the flue pipe to regulate the chimney draught.
• Manual flap for the primary air.
• The air control, achieved by the means of a capillary thermostat, smoothly regulates the temperature of the hot water from 50°C to 90°C, increasing the performance and economy of the combustion process.

Achieving the desired heat output depends on:

• the selected fuel with the necessary caloricity and humidity
• its subsequent kindling and refueling
• the regulation of the primary and the secondary air
• the regulation of the draught
• the organizing of effective air heat exchange, etc.

Installation instructions

• Ask for an advice from a professional before connecting the boiler to the chimney and the central heating system.
• The boiler must be placed on a horizontal, nonflammable floor. To protect the floor, a nonflammable pad can be placed below the wood boiler. If a pad is used, it should stick out at least 50 cm in front of the boiler and 30cm on each side.
• In the immediate vicinity of the boiler (within 80cm of each side) no objects should be placed if they are flammable or can be damaged from the heat.
• All elements connecting the boiler to the chimney must be firmly fixed, but not in a way that places them inside the passage section of the chimney.
• The chimney pipes should be the same diameter as the one on the boiler.
• It is recommended to connect the boiler to a separate chimney. Other heating bodies can be connected to the same chimney only if it is designed for that purpose.
• The flow of fresh air inside the boiler must be at least 4 m³/h for every kilowatt of heating output. If needed, air can be supplied from another room or from outside.
• The burning process of the boiler must not be deprived of air when gravity or forced aspirations are at work, because in such cases the burning is incomplete and/or flue gas can be returned in the room.
• The boiler should be connected to a central heating systems with suitable fittings and fixtures, according to a prepared beforehand heating project.

WARNING!

 - Not to be fired when not connected to radiators / fan convector heaters. Burning wood without water in the boiler will cause it to crack and subsequent loss of the guaranty. 

Recommendations:

- We recommend the installation to be done in an open type system. When connected in closed circuit system it must be fully protected using safety valves for temperature and pressure up to 1.5bar.

- All elements of the installation must be protected from freezing. In installation with forced ciculation we recommend the pump to be backed-up by a UPS.

- In any installation with copper parts the boiler should be protected against corrosive electrolysis using magnesium sacrificial anode or similar protective system
