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.
■
Angus Evo Series boilers are available in four output series (determined by the number of segments 3, 4, 5, 6) from 17 to 41 kW.
■
The cast iron boiler body comprises of segments and serves as a combustion chamber (including combustion gases routes),
and at the same time as a water reservoir (including water routes). Segments are of three types – front and rear, inserted
between which are 1 to 8 middle segments (of the same kind). By assembling and joining together an appropriate number of
segments, a boiler body of the required size is constructed (both the combustion chamber and the water reservoir). Assembled
boiler body is equipped with necessary pipe sections for water connection. It also has brackets for fitting thermostat sensors
and brackets on feet for fastening the boiler to the base. Attached to the cast iron boiler body are sheet metal covers which
are fitted on the inside with thermal insulation.
■
To ensure that the boiler functions correctly and runs economically, it is important that its nominal output is equal to the thermal
losses of the heated premises.
■
Choosing a boiler of insufficient output will result in inadequate heating of the premises, and thus failure to provide a
heating comfort.
■
Choosing a boiler of unnecessarily high output will result in the boiler not running in full output, and as a consequence in
tarring and dewing.
Recommended fuel
■
Recommended fuels for Angus Evo boilers are coal, coke and firewood.
■
Optimal coal and coke granularity is 24-60mm.
■
Optimal firewood size is logs of diameter 40-100mm. Their length will depend on how many segments the boiler have.
■
Fuel must be stored in a dry place. To reach the boiler nominal output, water content in firewood must not exceed 20%.
■
Approximate stoking intervals (referred to as Burning Time) are shown in the Technical Data Table on page 3.
■
The boiler is stoked manually.
Please note
The boiler is not intended for burning any type of waste.
