3.6 Burner installation
3.6.1 Hole pattern
Make sure the hole pattern on the burner corresponds to the supplied flange
(refer to Technical data).
3.6.2 Burner installation
1. Install the flange with gasket on the boiler.
2. Fit the selected nozzle
(refer to Technical data).
3. Install the brake plate and check the ignition electrodes
(refer to Burner Servicing).
4. Mount the burner to the flange.
5. Insulate between the burner and boiler door to reduce radiated heat (if
necessary).
3.6.3 Oil lines
1. Check the dimensions of the oil lines (refer to Pump instructions).
2. The oil filter should be fitted to the incoming oil line. If a degasser is
installed, the oil filter should be fitted to the oil line up to the degasser
in order to prolong the service life of the oil filter.
3. For single pipe systems, the return plug must be removed
(refer to Pump instructions).
4. When installing oil hoses, check that the supply and return hoses are
fitted to the appropriate connection on the oil pump. The hoses must
be located so that they do not bend or become subject to tensile load.
5. Bleed the oil system. Dry running will damage the oil pump.
6. The vacuum in the suction line should not fall below 0,3 bar during
start-up.
3.6.4 Electrical connection
If the boiler does not have a pre-fitted connector, connect to the supplied
connectors (x2) as shown in the wiring diagram.
1. Switch off the main switch.
2. Connect the Europlugs (x2) as shown in the wiring diagram.
3. Fit the Europlugs (x2) to the burner.
4. Turn on the main switch.
3.6.5 Check oil line seals
Once the burner has been installed and commissioned, the seals of the
various coupling elements should be checked.
When a leak is detected, it is usually sufficient to tighten the coupling
element that is leaking.
