2.2.5. Forced draught fan
Forced draught fan is intended to supply su ffi cient amount of
air to the furnace. Amount of supplied air varies and it is au-
tomatically controlled by the controller. Detailed information is
contained in the
Forced draught fan user’s manual enclosed to
the boiler documentation.
2.2.6. Set of feeder with burner
Feeder unit with the burner is driven by the motoreducer and
it is installed on the left or the right side of the boiler. Its task is
to take the fuel from the container and feed it automatically to
burner part. PSQ trough burner is used in the AGRO Multi boiler
series.
Design of the unit allows quick assembling and disassem-
bling. Fuel container with tightly closed cover is installed on the
feeder unit. Detailed information is contained in the
Feeder user’s
manual enclosed in the boiler documentation.
2.2.7. Outlet water connection
Outlet water connection is a connection to the central heating
system on the hot water side.
2.2.8. Return water connection
Return water connection is a connection of boiler to the cen-
tral heating system on the cold water side returning from the
system.
2.2.9. Flue with a damper
Flue with rotary fl ue gas damper is an integral part of the boiler,
which discharges fl ue gas towards the chimney fl ue.
2.2.10. Flue gas swirlers
Flue gas swirlers are located inside the convection ducts to swirl
fl ue gas stream, what has an in fl uence on the increase of e ffi -
ciency and the boiler power. They should be removed in case of
weak chimney draught.
2.2.11. Water tubes
Water tubes (only AGRO Multi 12) are steel components fi lled
with water permanently located in the convection ducts. Their
function is to extend the heating surface of the boiler, that is to
increase its power and e
ffi ciency by more e ffi cient heat recep-
tion from the fl ue gases.
2.2.12. Fire- fi ghter
Thermal safety valve protecting the fuel in the container against
ignition. In case of
fi re glow reversing or getting to the feeder
pipe, the valve temperature sensor opens the valve and fl oods it
with water from a 5l container connected with a hose.
