6.1.Verification activities befor commissioning
Before the boiler commissioning it is necessary to check and bring into a correct status :
-
water volume in system according to manometer
-
open all slide valves and valves between the boiler and heating system
-
correct burner mounting and its connection to electricity network (we recommend to have the box main
switch in “0” position before we connect the supply cord with network )
-
fuel supply opening
-
regulation and safety elements setting
6.2. Operation
The boiler can be operated with both gaseous and liquid fuels and with burners tested and approved by
Engineering Testing Institute Brno. Recommended types of burners - see chap. No. 3 – VIADRUS G 700 boiler
technical data .
The boiler operation itself is controlled by the burner automatics and setting of individual regulation
elements. The boiler operation in individual stages is signalled by pilot lamps on electric panel.
7. Boiler operation by user
7.1. Setting of regulation elements.
Setting of temperature stage I. (reduced output) to 50 - 90°C range (optionally 50 - 115°C)
Setting of temperature stage II. (nominal output) to 50 - 90°C range (optionally 50 - 115°C)
in low-temperature regime the heating water temperature is set to 50 - 75 °C range.
safety thermostat is permanently set to 100°C by manufacturer (optionally to 120°C).
In case of switching off – defect signalling is alight on electric panel – it is necessary ( after having found
out the reason and possible defect elimination) to bring the thermostat into its on-state position by pressing the
button on the rear box panel.
The required chimney draught is min. 0,2 mbar. A probe positioned on sight-glass body serves for
overpressure measuring in combustion chamber.
7.2. Electric panel – basic design
The electric panel consists of basic parts as follows :
-
electric panel itself with network module
-
capillary manometer
-
capillary thermometer
-
service thermostat stage I.
Main switch
Blind flange
