INSTALLATION
Installation of the boiler can only be done by a company or individual with the necessary profes-
sional accreditations. Installation should be performed so that it meets the minimum require-
ments of the SFS 3332 standard. Electrical and burner installations must be done only by a
qualified company or individual.
Space requirements
An area of 1 metre must be reserved in front of the boiler for cleaning and maintenance pro-
cedures. Plumbing connections are located on top of the boiler with the exception of the return
from the accumulator, which is on the side.
Flue connection and combustion air opening
The boiler can be directly connected to a vertical flue. The seams can be sealed with 350 °C
silicon paste. If the flue is made of bricks, use the supplied square elbow to connect the boiler.
Flue requirements: Minimum Ø 140 mm, and for a masonry flue, free cross-sectional area of at
least 200 cm². If an oil burner is used as well, the flue requirement is a brick flue lined with acid-
proof thin-walled pipe tube or an acid-proof flue element. The free surface area of the combus-
tion air opening must be 1.5 times the diameter of the flue. The combustion air opening must
never be covered.
Flue gas fan
The Vedo has versatile assembly options that allow it to be fitted with different chimney so-
lutions. The standard delivery always includes a flue gas fan. The standard connection to the
chimney is straight up (image 1). Make sure to leave enough space for cleaning when installing
the pipe. A chimney elbow piece also comes as a standard accessory. It allows the boiler to be
connected to a brick chimney (image 2).
