Product description.

Comfort S burners are modern and advanced devices for combustion of

biomass in the form of wood pellets. The burners have a rotating combustion
chamber,   which   changes   its   position   during   burner   operation   to   clean   the
furnace of slag and ash generated as a result of combustion.

Burner starting, burning, extinguishing and cleaning in the burner are

done automatically, which makes it a convenient device. The burner is started
by feeding the initial batch and igniting the fire by heating the fuel to the
flashpoint using the igniter located in the burner. Burning and extinguishing are
managed using the controller (see the Controller Manual). Cleaning consists in
turning the combustion chamber, which makes it possible to discharge burning
residues into the ash pan. The combustion chamber rotates cyclically, which
makes it easier to burn 100% of fuel, improving the combustion economy and
ecology. Cleaning the burner also extends the life of the burner combustion
chamber as it is evenly loaded on its entire circumference.

Comfort S burners are compatible with solid fuel central heating boilers

and with some gas and oil boilers equipped with a combustion chamber and
ash pan.

VENMA burner is a very eco-friendly device, as it is intended for the

combustion of wood pellets, fuel that comes from renewable sources.

The burner is controlled by a controller included in the set, smooth fuel-

oxygen control allows you to adjust the device power to your needs. Up to 4
pumps and 3 mixing valves can be connected to the controller. It supports up
to 6 temperature sensors (including central heating, DHW, valve, return, buffer
sensors).   Many   facilities   and   options,   such   as:   PID   exhaust   sensor,   room
controller   or   lambda   probe,   will   make   operation   easier   and   maximise   the
comfort when using the burner.

The burner is equipped with multiple fire protection measures which will

cut off the fuel supply to the device in the event of failure or overheating.
Interruption of electricity supply will not adversely affect the device, as the
amount of fuel in the combustion chamber is small.

Fuel delivered to the burner should be stored in a sealed and closed

container and should be transported using a feeder with a VENMA spiral insert
of appropriate length and power.

The basic fuel is pellets with a valid 

DIN Plus

 or 

EN Plus

 certificate.
