Incorrect start-up makes the manufacturer's guarantee for the unit void. If you have questions, please contact our Technical
Customer Service.
4.1 Initial start-up
After the oil condensing boiler has been installed and fully connected, it can be started up by trained staff.
Requirements
– The oil condensing boiler is correctly connected. If a pressure device is used as separate oil pump, the installation site must
also be secured by using a leakproof tray and a filter cup made of metal (see section 3.4.1).
– The oil condensing boiler is fully connected.
– The heating system is filled and charged at the correct pressure.
– The oil valves are open and the oil line is topped up.
Tests prior to start-up
• Check all connections for leakage.
• Check all points on the checklist supplied (see chapter 4.2). Log the test results on the checklist.
The oil condensing boiler can only be provisionally put into service if all points on the checklist can be answered with Yes.
Bleeding the oil line, checking the oil pressure
The oil line must be completely vented at the beginning of the start-up and the oil pressure must be checked.
• Connect vacuum meter to the oil pump (Vacuum meter connection, fig 4-2, pos. 2)
• Switch on the mains switch. Wait for the start phase.
• Open the venting screw on the oil filter.
• Vent oil line and measure the oil pressure on vacuum meter.
Î The vacuum may be maximum 0.4 bar (better: 0.2 bar).
WARNING!
An oil condensing boiler not started up properly can be a health and safety risk endangering human life and
adversely affect its operation.
• Start-up of the oil condensing boiler may only be carried out by authorised and trained heating engineers.
