5.3Clearances around boiler
At least the following clearances should be achieved around the boiler. When the boiler is placed
to the boiler room enough distance should be left for easy fuel loading to bunker, easy removing
the geared motor and auger and easy servicing.
5.4 Circulation pump
We recommend building a forced water circulation system accompanied with a sufficient pump.
Refer to the system diagrams given further in this manual to find the right position of thepump
within the hydraulic circuit.
Your boiler automatically switches the pump on and off according the program stored in its PCB.
That is why circulation pump must be driven by the control panel. Wiring to the pump is supplied
at the back of the boiler.
5.5 Rules for hydraulic circuit
Cortina boiler can be installed in a pressurized heating circuit with addition of a closed expension
tank in respect with one of the following schemes. If heat demand of building differs from the
nominal capacity of boiler, we recommend a buffer tank between primary circuit and heating
installation. Hydraulic circuit should have at least the equipments listed below:
Circuit without buffer tank:
