Connection with separate pipes
fig. 15 - Examples of connection with separate pipes (
= Air /
= Fumes)
Table. 4 - Typology
For connection of the separate ducts, fit the unit with the following starting accessory:
fig. 16 - Starting accessory for separate ducts
Before installation, check the baffle to be used and make sure the maximum permissible
length has not been exceeded, by means of a simple calculation:
1.
Completely establish the layout of the system of split flues, including accessories
and outlet terminals.
2.
Consult the table 6 and identify the losses in m
eq
(equivalent metres) of every com-
ponent, according to the installation position.
3.
Check that the sum total of losses is less than or equal to the maximum permissible
length in table 5.

Connection to multiple flues or single flues with natural draught
To connect the
DOMIcondens HE 26 C
boiler to a multiple flue or a single flue with nat-
ural draught, the flue or chimney must be expressly designed by professionally qualified
technical personnel in conformity with the current standards and regulations.
In particular, flues and chimneys must:
•
Be sized according to the method of calculation given in the standard.
•
Be tight with respect to the products of combustion, resistant to the fumes and heat
and impermeable to condensate.
•
Have a circular or square cross-section (some hydraulically equivalent sections are
permissible), with a vertical progression and with no constrictions.
•
Have the ducts conveying the hot fumes at a suitable distance or separately from
combustible materials.
•
Be connected to just one unit per floor, for not more than 6 units (8 if there is a com-
pensation duct or opening).
•
Have no mechanical suction devices in the main ducts.
•
Be at low pressure, all along their length, in conditions of stationary operation.
•
Have at their base a collection chamber for solid materials or condensate, of at least
0.5 m, equipped with an airtight metal door.
Type
Description
C1X
Wall horizontal exhaust and intake. The inlet/outlet terminals must be concentric or close enough to be
undergo similar wind conditions (within 50 cm)
C3X
Roof vertical exhaust and intake. Inlet/outlet terminals like for C12
C5X
Wall or roof exhaust and intake separate or in any case in areas with different pressures. The exhaust
and intake must not be positioned on opposite walls.
C6X
Intake and exhaust with separately certified pipes (EN 1856/1)
B2X
Intake from installation room and wall or roof exhaust
IMPORTANT - THE ROOM MUST BE PROVIDED WITH APPROPRIATE VENTILATION

NOTES
•
N/A = Not applicable
•
Also, the terminal must be at least 150 mm (in case of forced intake)
from an opening made in the structure of the building to house a fitted
element such as a window frame.
•
Positions of condensate drain terminals: if the fume exhaust is pro-
vided for at a low level, the potential effect of the flue gas cloud must
be considered. Special flue gas management kits are available by
request.
•
The flue gas cloud must not be directed towards:
-
A frequented approach
-
A window or door
-
An adjacent property
