Flue Gas Exhaust - Palazzetti ECOFIRE Aria Serie Bedienungsanleitung

5.5 FLUE GAS EXHAUST

The stove operates with negative pressure in the
combustion chamber, and consequently the À ue
gas discharge must be airtight.
The stove must be connected to its own separate
flue gas exhaust system capable of ensuring
adequate atmospheric dispersion of the combustion
byproducts.
The components making up the À ue gas exhaust
system must be suitable for the speci¿ c operating
conditions and bear the CE mark.
The pipes used to discharge the À ue gas must have
a nominal diameter of 8 cm with gaskets (up to 5
metres in length), or 10 cm with gaskets (for lengths
exceeding 5 metres) (Fig. 5.7).
The À ues should be suitably insulated (e.g. using
rock wool) or made using double wall steel pipes,
except for the initial vertical section inside the room.
An initial vertical section measuring a minimum of
1.5 metres is required to ensure correct À ue gas
exhaust.
There should be at least three changes in direction
along the À ue, in addition to the À ue connection
at the rear of the stove, using 45 or 90° angle
connectors or 'T' connectors.
Use always a 'T' connector with inspection cap on
all horizontal or vertical changes in À ue direction.
The maximum length of horizontal sections is 2-3
m with an upwards slope of 3-5% (Fig. 5.7).
Anchor the À ues to the wall using special collars.
The À ue gas exhaust attachment MUST NOT BE
connected to:
- a chimney used by other heat generators
(boilers, stoves, ¿ replaces, etc.....);
- air exhaust systems (range hoods, vents,
etc.....) even if these are ducted.
Shut-off or draught valves must not be used.
Combustion byproducts must be discharged
through the roof.
If the À ue is longer than 5 metres and there is
insuf¿ cient draught (many changes in direction,
unsuitable discharge terminal, etc.) flue gas
exhaust may be less than optimum. In these cases,
the operating parameters will need to be modi¿ ed
(À ue gas exhaust and pellet load) to adapt the stove
to the actual characteristics of the À ue. Contact
technical service for this procedure.

RMETICA SERIES STOVES
For "Ermetica" series pellet stoves a special coaxial
pipe can be used to both discharge the À ue gas and
duct the combustion air from the outside (Fig. 5.5
