Flue Gas Exhaust - CASATELLI TOMMASO G Manuel D'installation Et D'entretien

"Sealed" mode installation
These pellet stoves allow the following possible
installation alternatives:
• ducted combustion air using a coaxial pipe to
discharge the flue gas and take in fresh air;
consequently no fresh air vent is needed in the
room (Fig. 5.5 A, B=Air intake C, D=Flue gas
outlet);
• connect the stove combustion air intake to the
fresh air opening using a special pipe (Fig. 5.6).

5.5 FLUE GAS EXHAUST

The stove operates with negative pressure in the
combustion chamber, and consequently the flue
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 flue gas exhaust
system must be suitable for the specific operating
conditions and bear the CE mark.
An initial vertical section measuring a minimum of
1.5 metres is required to ensure correct flue gas
exhaust.
There should be at least three changes in direction
along the flue, in addition to the flue connection
at the rear of the stove, using 45 or 90° angle
connectors or 'T' connectors (Fig. 5.7).
Use always a 'T' connector with inspection cap on
all horizontal or vertical changes in flue direction.
The maximum length of horizontal sections is 2-3
m with an upwards slope of 3-5% (Fig. 5.7).
Anchor the flues to the wall using special collars.
The flue gas exhaust attachment MUST NOT BE
connected to:
• a chimney used by other heat generators
(boilers, stoves, fireplaces, 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.
