4.5 Burner installation
Prepare heating appliance
The diagram shows the refractory for a heating appliance
without a cooled front. The refractory can be flat faced, or
take a conical shape (≥ 60°). Refractory may not be
required on boilers with water-cooled fronts, unless the
manufacturer gives other instructions. The refractory must
not project beyond the end of the combustion head.

Connecting the oil hoses
If the oil hoses are connected incorrectly, the
oil pump can run dry and thus become
damaged.
Note the directional supply and return arrow
indications on the oil pump and filter when
connecting the hoses.
Ensure the hoses are not kinked and are
tension free.
Danger of getting burned
Some burner parts (e.g. flame tube, burner
flange, etc.) become hot during burner
operation and should be allowed to cool
prior to service work being carried out.
Installation of burner rotated through 180°
The burner can also be mounted turned through 180°. In
doing so the oil line must be changed (oil line available as
an accessory).
☞ Turn the oil pump through 180° and fit new oil line
(accessory)
☞ Turn the nozzle head and diffuser so that the ignition
electrodes are uppermost.
Note when installing the nozzle and diffuser:
• Nozzle selection, see Ch. 4.7
• Distance between nozzle and diffuser, see Ch. 7.5
• Setting the ignition electrodes, see Ch. 7.4
Note Change the nozzle as described in Ch. 7.3.
