Setting up an oil condensing boiler
3.4.1 Selecting the installation site
The installation site for the oil condensing boiler must satisfy the following minimum requirements:
Installation height
The bottom edge of the condensate drain connection on the unit must be higher than the outlet height of the condensate drainage
hose, otherwise condensation can accumulate in the drain.
• If setting up with an extension storage tank, the boiler pedestal height must be minimum
80 mm
.
Installation area
– The base must be solid, even and horizontal and must have sufficient load bearing strength. Install a pedestal if necessary.
– Observe the installation dimensions (see chapter 3.1).
Installation room in general
– There are no special conditions for ventilation of the installation room for operation independent of the ambient air (using a
concentric air/flue system).
– When operating partially independent of ambient air and with ambient air dependent operation, the installation room must
have a ventilation opening of at least
150 cm
2
to the outside.
– When operating partially independent of ambient air and with ambient air dependent operation, the installation room must be
free from aggressive vapours (e.g. hair spray, perchloroethylene, carbon tetrachloride), heavy dust formation and high
atmospheric humidity (e.g. utility room).
Set-up in the attic
If the A1 condensing boiler is installed in the attic and the oil is stored in the rooms below it, the oil pump of the burner is generally
not adequate. Since the vacuum on the suction side exceeds the value of 0.4 bar, the oil must be supplied to the burner through
a separate pump. ROTEX urgently recommends using a
suction aggregate
.
The
minimum height of the flue gas pipe
must be
2 m
in order to avoid malfunction at start or during operation of the burner.
Set-up in garages
The oil condensing boilers of series A1 BO are basically suitable for being set-up and operated in garages. Requirements:
– Operation independent of ambient air,
– A durable instruction manual placed in a very visible place near the boiler,
– The construction must include a protective device against mechanical damage (vehicle!) for the entire system (e.g. bracket
or deflector).
Heating oil storage in the installation room
As a general rule, construction specifications allow up to 5000 litres of heating oil to be stored in the
installation room (according to the Firing Ordinance of the state) if the building is in Building Category 1 and
the installation room is not a living room.
CAUTION!
If using a pressure aggregate, oil could escape if there is a fault. Escaping oil can cause serious damage to the
environment.
• Install boiler in a leakproof tray and secure through a float switch (connection through additional plug strip
ZSÖ
,
15 40 67
).
• Use only a metallic filter cup (never Plexiglas).
