Filling The Fuel Storage Unit; Horizontal Extraction System And Spring Extraction System; Pellet Extraction Auger; By Dumping - Viessmann Vitoflex 300-UF 530 Installation And Operating Instructions Manual

Operation

Filling the Fuel Storage Unit

When storage facilities for wood are required, the wood
should be kept at least 5 ft. (1.5 m) from the heating
appliance.

Horizontal extraction system and spring extraction system

If any excess or negative pressure develops in the silo
during the filling, the facility has to be switched off using
the function button on the control panel. After doing so,
complete filling the silo evenly and turn the facility back
on, using the function button on the control panel. Carry
out refilling in the same manner.

Pellet extraction auger

Switch off the facility using the function button on the control
panel and wait until there is no more fuel in the feed auger.
Slowly and evenly fill the silo until the extraction auger
is covered approx. 10 in. to 12 in. (250 mm to 300 mm)
high over the entire open area. Level out any mounds that
form from pouring.
Switch on the facility using the function button on the
control panel and wait until the metering container on the
feed auger has filled.
If any excess or negative pressure develops in the silo
during the filling, the facility has to be switched off again
using the function button on the control panel.
After doing so, complete filling the silo slowly and evenly.
The facility can then be turned back on using the function
button on the control panel. Carry out refilling in the same
manner.

By dumping

Horizontal extraction system and spring extraction system
Heating system in operation: if the articulated arms or
spring-mounted plates are still covered by fuel, refilling
can be carried out immediately.
- If the articulated arms or spring-mounted plates are
no longer covered by fuel, fill the silo evenly to
approx. 12 in. (300 mm) above the articulated arm or over
the spring-mounted plates. As soon as the articulated
arms or spring-mounted plates have retracted through
a request for material, the refilling can be continued.
Heating system not in operation:
- If the articulated arms or spring-mounted plates are still
covered by fuel, refilling can be carried out immediately.
- If the articulated arms or spring-mounted plates are
no longer covered by fuel, fill the silo evenly to approx.
12 in. (300 mm) above the articulated arm or over the
spring-mounted plates. Then activate the "SILO FILLING"
function. To do so, press the LOADER SYSTEM button
(F4) and then the left arrow button (<).
Select "YES" and confirm with "OK". Wait until
the articulated arms or the spring-mounted blades
move under the cup washer, complete by evenly filling
the silo. The "SILO FILLING" function enables the
filling of the combustion chamber.

By blowing in

IMPORTANT
The heating system has to be shut off (danger of excess
pressure or negative pressure caused by the action of
blowing-in). Filling procedure as described in the section
"By dumping".
Fixing malfunctions in the feed system
Refer to the Installation and Operating Instructions for
details on the automatic fuel-feeding device.
If fuel hopper is installed, do not alter equipment in any
way. The cause of motor malfunctions in-feed systems
is usually clogging by large pieces of wood or foreign
matter.
Switch off the facility using the function button on the
control panel and wait until there is no more fuel in the
feed auger. Fill the silo evenly to approximately 12 in. (300
mm) above the articulated arm or over the spring-mounted
blades, switch on the facility using the function button on
the control panel and wait until the articulated arms or the
spring-mounted blades go under the cup washer.
CAUTION
DANGER OF INJURY:
Always turn OFF the main switch before carrying out any
repair of a malfunction on feed systems and every time
before a maintenance lid is opened or a protective device
is removed!
Because of the automatic operation of the system it is
impossible to foresee the time the conveying equipment
will be turned on.
Note: Viessmann recommends the installation of carbon
monoxide detector(s) inside the fuel storage area.
IMPORTANT
The fuel storage area/room must be designed, operated
and maintained to national, provincial and local codes and
requirements.
WARNING
The wood chip/pellet storage room must be adequately
and permanently ventilated. Ensure the door or latches
are securely locked open during presence in the room.
No smoking, fires or open flames are permitted.
