Depending on your specific heating system, the safety equipment
must be tested by a heating contractor.
The heating system must be completely filled with water. Subject to the
boiler output and operating temperature of the heating system, the water
quality for heating systems is regulated by local regulations governing
"Water quality in heating systems with hot water boilers".
Observe the system pressure. If necessary top up with water.
Never use boiler water for domestic use.
Check whether the ventilation of the boiler room is ensured in accordance
with local regulations.
The air supply to the boiler must not be obstructed, otherwise
there is a risk of suffocation.
Never position objects directly on the boiler - maintain a minimum
clearance of 40 cm. Otherwise there is a high risk of fire.
If necessary top up with water. When filling the heating system, the
shut-off valves must be open.
Connect a water hose to the boiler drain & fill (BDF) valve and open the
mains water tap. Open the BDF valve to provide a moderate flow rate and
fill the heating system to approx. 1.5 bar. Check the water pressure at the
pressure gauge. Vent the system. The boiler must be topped up, since
heating water will only fully deaerate after several hours' heating operation.
Generally leave the system full - except where there is a risk of frost.
The connection required for filling between the tap water and heating
water must be removed after the fill has been completed. Otherwise
there is a risk that your tap water will be contaminated by heating water.
The appliance may overheat if it is operated without water.
The siphon must be fitted and filled.
Regularly check the water level. The pressure gauge must indicate
between 2.0 and 2.5 bar. Your heating contractor will explain how to top
up your system. Do not supplement your heating water with additives,
otherwise components may be damaged.
