Vitoligno 300-C Installation/Service
Installation
Connections on the Flue Gas Side
Note:
Install a flexible connection piece in the flue to
prevent sound transmission from the flue gas fan.
Never brick the flue pipe into the chimney.
If necessary, provide additional sound insulation
on
site.

1. Install the flue pipe rising to the chimney (preferably 45°).
Flue pipe diameter 6 in. (150 mm)
Max. flue pipe length to the chimney
D
: 118 in. (3 m)
Note:
Let the flue pipe connector project about
b
in. (1 cm)
into the chimney. This prevents condensate or
rainwater from the chimney running into the flue pipe.
2. The entire flue pipe with cleaning aperture must be
gas-tight.
3. Thermally insulate the flue pipe, minimum insulation
thickness
1
a
in. (30 mm).
4. Install a barometric damper (accessories) in the
chimney.
Refer to the barometric damper installation
instructions (field supplied).
This boiler must be properly vented. Use a vent material
certified for use with solid-fuel fired equipment.
Do not use galvanized steel.
IMPORTANT
The Vitoligno 300-C is output-controlled within a range
from 30%-100% of the rated boiler output. This produces
flue gas temperatures from min. 212°F (100°C) to max.
482°F (250°C).
An insulated chimney should be provided to prevent sooting,
condensation and creosote formation.
The distance from the flue gas exhaust blower to the
chimney should be as short as possible. 90° elbows
should be avoided if possible. Flue gas pipes of more than
40 in. (1 m) in length must be insulated.
The connection to the chimney should be made such that
it rises at an angle of 30°- 45° (to prevent excess ash
accumulating in the lateral section of the vent pipe).
The flue gas line, including the lead-in into the chimney,
must be gas-tight.
Single acting barometric draft regulator
The barometric draft regulator must be the same diameter
opening as the chimney for which the vent is sized 6 in.
(150 mm).
For room sealed operation and a draught > 0.02 “w.c.
(> 0.15 mbar), a barometric draft regulator approved for
room sealed operation must be used.
