In the lower part of the boiler body is located a support foot which
enables levelling of the feeder in the range of 2 cm. The multi-fuel burner
has an air chamber which serves as an expander for the air delivered by
the blower, which is a part of the burner. The multifuel ignition has tubes
that allow intalling a 700W ignition. The mounting plate of the multifuel
burner is used to mount the burner on the central heating boiler. The
connection between the feeder and the boiler body must be secured with
a seal which is delivered with the equipment. If the seal is missing please
o
use heat- resistant silicone of resistance of 1250 C.
The burner has a return air inlet that allows for significant removal of
harmful compunds included in the fumes and at the same time enhancing
the burning process.
Hot plate - also called a deflector for fumes is not necessary as an
additional component. In the multifuel burner this function is provided by
the burner pipe vault. Its main purpose is to burn out the chemicals that
occur during burning fuel.
The burner is equipped with a 1 / 2 inch coupler and a pipe that can be
connected to the thermostat valve- so called „Fireman”. Its role
is to extinguish the smouldering biomass and prevent it from getting into
the container. The system itself is powered independently from the
controller and boiler systems.
It consists of a valve which is installed in the
upper part of the feeder where it can safely stop the returning smoulder
(
1 / 2 ” coupler) and a sensor inserted into a pipe which is attached to the
fuel feeder.
It is recommended to use the BVTS system of the following
