Installation
Instructions for attachment to the flue
Accessory 4880
is required for the installation.
1.
Cut the flue-gas pipe, the insulation channel and the cover sheet metal to a
length at which they extend to the inner surface of the flue.
2.
Fasten the hoses to the heater with clamps. The flue-gas pipe must be tight
-
ened firmly with a pipe clamp.
3.
Put the heater in place, and fasten it to the floor or the base housing.
4.
Insulate the joint between the flue-gas hose and flue with acrylic compound.
5. The device is ready for use after you connect the power cord and the fuel hose.
Note!
If you choose to lead in the combustion air from under the floor, ensure there is suf
-
ficient ventilation in the foundations beneath the floor. Install the protective spiral on
the end of the hose.
In a tall (over 5 m) flue, with a large cross-sectional surface (over 15x15 cm), the
temperature of the flue-gases decrease so much that the moisture in them con
-
denses, resulting in funnel corrosion and a weakened air flow. Due to this, a brick
flue should be cased with a stainless steel pipe (diameter: 50–70 mm) and the gap
between the pipe and the flue filled, for example, with LECA.
Combustion air must not be taken from the flue.
