Oil tank and burner
7.1 Fuel
The boiler is only to be operated with the fuel stated on the boiler
rating plate.
The UltraOil
®
boiler can be operated with the following types of fuel:
- Low sulfur fuel oil according to DIN 51 603 / ÖNorm C 1109
- Eco low sulfur fuel oil SN 181 160-2 / 2008
7.2 Filling the oil tank
When the oil tank is being filled, the system must always be switched off by means
of the ON/OFF switch on the heating boiler. It may only be switched on again after
a waiting time of about 2 hours. Filling of the heating oil tank is to be supervised by
the oil supplier; we can accept no responsibility whatsoever for the oil tank being
overfilled.
7.3 Burner setting
Your Hoval burner was set in the factory to suit the boiler output. Fine adjustment is
performed by the heating engineer or the Hoval Service when the trial operation is
carried out (for the output setting, see “burner setting”, page 6).
7.4 Boiler room and supply of fresh air
The burner requires large quantities of fresh air to burn the fuel oil without produc-
ing smoke. Therefore it is always essential to ensure an adequate supply of fresh air
to the boiler room. Contaminated air (for example, with dust or textile fibres) rapidly
causes the burning to deteriorate and can shorten the service life of the boiler. For
this reason, it is desirable that the boiler room is always kept clean and free of dust
and dirt. No chemicals may be stored in the boiler room, nor in the fresh air supply
route to the boiler room.
7.5 Putting into service
Check the water level in the heating system
Check the level of the oil in the oil tank with the dip-stick
Check the settings of the boiler operating elements (see from page 15)
Check the oil feed to the burner (slider stop valve next to the oil feed open)
Check the cut-outs on the switch-panel
Turn the emergency switch to “ON” or put the plug in.
The burner can now be turned on by switching on the main switch on the heating
boiler.
7.6 Taking out of service
When shutting down the oil burner for a short period only, it is sufficient only to switch
off the ON/OFF switch on the heating boiler. If the burner is to be shut down for a
longer period, it is recommended to close the oil feed valve.
7.7 Maintenance of the burner
An important precondition for economical operation as well as for keeping the air
clean is the perfect technical condition of your firing equipment. The burner should
be inspected at least once a year by a specialist. We strongly recommend you to
conclude a maintenance contract.
