If the adjacent walls and flooring are made of materials that are not heat-resistant, it is necessary to ensure adequate
protection and use of non-combustible insulation material.
To protect the flooring from combustible materials, it is mandatory to insert a metal plate that is 3 to 4 mm thick with the
front side at least 30 cm greater than the depth of the boiler, under the boiler. The pellet boiler must be installed in
accordance with the sketch, which defines the distance from the walls (Figure 2)
Figure 2. The minimum distance of the boiler from the walls
If the pellet boiler is installed in the boiler room where there are other devices that suck the air (other boilers, various
types of suction fans, etc.), make sure that the volume of air entering the premise is sufficient to guarantee safe
operation of the boiler.
If the chimney passes through the ceiling it must be sufficiently insulated with coating of non-flammable insulation
material.
After the pellet boiler is set in place, level it (bring it to a horizontal position) with adjustable legs.
The flue gas exhaust system MUST NOT BE CONNECTED TO:
-
the uptake used by other heating devices (boilers, furnaces, fireplaces, etc.),
-
the system for air extraction (from the hood, suction fan, etc.).
It is prohibited to install barriers for the regulation of the flow of flue gases!
The connector of the Ø80 mm flue pipe from the pellet boiler to the chimney should have the following characteristics:
-
total length of up to 5 m (in the case of the connector of greater length connecting pipes diameter should be
increased to Ø130 mm),
-
each elbow of 90˚ reduces the total length of the flue pipe by 1 m,
-
cover intended for cleaning should be located on each elbow,
-
pipe joints need to be sealed.
In case the resistance in the exhaust system is too high (numerous elbows, inappropriate terminations, bottlenecks
etc.), the flue gas exhaust is not guaranteed and it is necessary to increase the connecting pipes and elbows to greater
dimensions, i.e. to Ø130 mm. Also, when the chimney does not provide proper flue gas exhaust, it may cause
malfunction and consequently alarm activation in the GRANDE boiler. It is recommended that the chimney is inspected
by a professional person before installation of the GRANDE Boiler.
The system for discharging flue gases from the boiler functions at the underpressure generated in the combustion
chamber and the faint pressure in the Ø80 mm flue pipe. Therefore, care should be taken to provide complete tightness of
the flue pipe.
It is necessary to carefully analyze the position and condition of the area through which the chimney passes. If the flue
pipe passes through the wall and/or roof it should be suitably insulated in accordance with the safety regulations for fire
protection.
