4.2.1 Exhaust gas flues approved by building
re gulations
The exhaust gases from the condenser oil-fired Hoval
UltraOil
®
boiler can be led away through a gas-tight,
exhaust gas flue resistant to high temperature and
to condensate. Only exhaust systems approved by
the respective country or state may be connected (in
Austria the approvals of the respective provinces are
to be observed). For transition from the exhaust gas
connection to the exhaust gas flue, the manufactur-
ers of the exhaust gas flues supply suitable boiler
connection fittings.
In planning and installation of the exhaust gas flue,
planning instructions and manufacturer’s instructions
for laying and building legislation regulations must be
observed. Discussions are recommended in good
time with the regional chimney inspector.
Your authorised Hoval agent will be pleased to sup-
ply you with an approved exhaust system to suit your
UltraOil
® boiler.

4.2.3 Project planning instructions
• The exhaust gas routing must be through tested
and approved exhaust gas pipework
• The exhaust gas pipework must be gastight, wa-
tertight, resistant to corrosion and acids and ap-
proved for use with exhaust gas temperatures of
up to 120 °C.
• The exhaust gas system must be suitable for op-
eration at pressure.
• The exhaust gas pipework is to be laid with gra-
dients to ensure that the condensate which oc-
curs in the exhaust gas system flows back into the
heating boiler and can be neutralised there before
discharge into the drainage.
• When using exhaust gas pipework of plastic, local
state or country regulations relating to the use of
the safety temperature limiter must be observed.
• The cross-sections are to be calculated for heat-
ing boilers without draughting requirement. Please
take note of the SIA recommendation No. 384/4
“Chimneys for building heating systems, determi-
nation of cross-sections”.
• In the exhaust gas pipework there must be a clos-
able exhaust gas measuring connection with cir-
cular internal diameter of between 10-21 mm in-
stalled. The connection must protrude beyond the
heat insulation.

4.2.4 Dimensioning flue gas system
Non-binding guide values:
The following formpieces have been taken into ac-
count in determining the dimensioning diagrams:
• 1 T-piece 90° for boiler connection
• 1 90° elbow to support the flue gas pipe in the shaft
• 1 component for the chimney end
