Connecting the device using a coaxial combustion air system
coaxial cables can have passages both through the wall and the roof of the building. In both cases,
you must observe the construction law in the region. The maximum length of the flue pipe should
not exceed 12 meters. Keep in mind that any 90° elbow is calculated as a 2 meter section, while any
45° elbow corresponds to a straight coaxial 1 meter pipe. It is recommended to pass the flue pipe
through the wall of the building by the use of 1 meter vertical section, angle 90° and a maximum
of 3-meter horizontal section. In the case of inserts with linear LpG burners, it is recommended to
use a 1 meter vertical section, a 90° elbow and a maximum of 2 meters of a horizontal section. The
connection between the device and the coaxial cable must be sealed with high-temperature silicone.
All ducts cannot be insulated. In the case of flue passage through the external wall of the building:
• Install the system in accordance with the applicable regulations, including any difficulties related
to the wind pressure on the terminal.
• In the case of flammable walls, provide an additional distance of 5 cm between the wall and the
outer surface of the coaxial cables. The remaining space is to be filled with protective insulation
against the ingress of moisture into the building.
• If the flue pipe is close to combustible walls, protect them with thermal insulation at a minimum
distance of 25 cm.
