Introduction 1. The boiler and all associated equipment must be installed and used in accordance with the installation design, all applicable legal regulations and technical standards and with the manufacturer’s instructions. The boiler may be used only for the purpose for which it is intended. 2. The boiler may be installed only in an environment which it is designed for.
Head loses fig.04 Operating instructions Angus Evo Series Boiler – general features ■ ■ ■ ■ ■ ■ ■ ■ Angus Evo Series solid fuel fired boiler is designed for heating both residential and industrial buildings. Besides professional installation, precondition for correct functioning of the boiler is the required chimney thrust and correct operation. Angus Evo Series solid fuel fired boiler is designed for heating systems which are suitable for forced circulation systems only.
Control and safety devices Angus Evo boilers are equipped with three main control elements: A chimney flap (Fig. 05), by means of which the chimney thrust can be controlled, i.e. the discharge of combustion fumes into the chimney. The flap is situated in the flue neck of the boiler, and is controlled manually. Chimney flap fig.05 Another thrust control element is a thermo-mechanical output regulator (Fig. 06). It is situated on the outlet from the boiler cast iron body.
Supply of secondary combustion air is controlled by an air rosette (Fig. 08), situated in the boiler’s stoking door, which has a direct effect on the level of emission. Hot water temperature can be checked on a thermometer (Fig. 09), which is situated in the front boiler cover above the stoking door. Air rosette fig.08 Thermometer fig.

Putting the boiler into service Checking the boiler before turning it on Before putting the boiler into operation, the service technician must check: ■ ■ ■ ■ Whether the installation conforms with the design; Whether the boiler has been filled in and is under pressure (on the thermo-manometer), and whether there are any leakage in the heating system; Connection to the chimney – connection must be approved by an authorised chimney sweep (chimney inspection); Functioning of the heating controls.
Stoking First shut the regulating hatch; this will shut supply of combustion air into the boiler. Then open the chimney flap completely. Partially open the stoking door and wait until all combustion gases have been sucked from the combustion chamber into the chimney. Only then open the stoking door completely and start stoking the boiler. After shutting the stoking door, set the chimney flap again and restore the functioning of the regulating hatch.
Boiler cleaning When the boiler is used, soot and fine ash accumulates on the boiler walls, mainly on heat exchanger ribs and in the flue neck, which reduces heat transfer and the boiler output. The actual quantity of soot and fine ash will depend on the quality of the fuel used and on the boiler operating conditions. If the boiler is oversized or was for some reason run at low temperatures, more soot is generated. This may also result in inadequate chimney thrust.

Boiler repairs The boiler may be repaired by an authorised service technician or organisation only. The user or owner may do only normal maintenance and simple replacements of some parts – e.g. sealing cords. Please note When repairing the boiler, original parts must always be used. Warranty and warranty conditions Angus Evo boilers are covered by warranty specified in the Warranty Certificate, Service Book and User and Installation Guide (chapter Introduction, Installing the boiler).
Installation Instructions Boiler installation – general information Angus Evo boilers must be put into service by an authorised services. A network of authorised service organisations which meet these conditions is available for all boiler installations, putting them into service and for warranty repairs. The boiler is designed to supply heating systems with gauge pressure up to 400 kPa which use water that meets the requirements of related standards (under no circumstances may the water be acidic, i.e.
Boiler location Angus Evo boilers can be located both on non-habitable premises (e.g. in boiler room, cellar, corridor) and in habitable rooms. The room in which the boiler is located must have a permanent supply of air necessary for the combustion process. The air must be free of halogen hydrocarbons and corrosive vapours, and must not be excessively humid and dusty. The room must be protected against frost, with ambient temperature within the range +5°C to +35°C and relative humidity not exceeding 80%.
Boiler room disposition layout Fig. 24 illustrates minimum distances which must be kept in order to ensure safe operation of the boiler room and allow manipulations with the boiler, such as cleaning and stoking. The distance between the front of the boiler and the wall should be at least the boiler length L plus 500mm. Minimum distances between the boiler side and rear should be 800mm, with the distance of the rear also determined by the way the boiler is connected to the chimney. fig.

Accumulator tank capacity NOTE: The heat can be supplied for example by an accumulator tank.
Flue pipe Installation Fig. 29 shows the proper flue gas connection with additional air equipment. Observe the following during the installation of the flue gas connection: ■ ■ ■ ■ ■ ■ Install a flue pipe connection with an inspection aperture for cleaning. Fasten the flue gas connector piece to the boiler. Feed the connector into the flue gas system on a short, ascending path. Avoid deflections, especially those with an angle of 90°. Fasten and support connectors sufficiently.
The figures below are only guide figures. The draft depends on the diameter, height, roughness of the chimney wall, and the temperature difference between combustion products and the outside atmosphere. We recommend the use of a chimney liner. Have precise calculations carried out by a heating engineer or flue installer. F = a.
