Technical details
3.1 Description of the boiler
The Hoval UltraOil
®
is a low-pollutant, energy-saving
oil-fired heating boiler. The UltraOil
®
has a combus-
tion chamber arranged vertically fabricated from
rustless stainless steel as its primary heating surface
and a secondary heating surface of a corrosion-re-
sistant aluminium alloy. The secondary heating sur-
face is so designed that the water vapour contained
in the heating gas condenses and the heat of evapo-
ration is utilised for the heating circuit. The UltraOil
®
is designed to be operated with heating oil EL.
3.1.1 The UltraOil
®
comply with the following
directives and standards
We hereby declare that the product described, as an
individual appliance, complies with the standards,
guidelines and technical specifications laid down.

EN 50082 Teil 1 ed. 01.92
EN 12828 prescribes low water level protection in closed
heating systems.
Substitute measures can be used in the case of boilers
with an output of up to 300 kW.
On boilers of type UltraOil (50), the safety disconnection
function during operation without water was tested. The
test was performed successfully.
i
Installation of low water level protection
on the UltraOil (50) is therefore not neces-
sary.
