5.3. Forced convection (optional fan)
At least two hot air vents must be opened.
The side air inlets in the base of the apparatus must remain closed.
For the fan air inlet, a passage through the brickwork must be provided of at least 450 cm² section
without fi lter, or at least 700 cm² with a dust fi lter (Warning! Take account of the coeffi cient of
passage of grilles and fi lters).
Proper separation of the air inlets and outlets in the masonry is vital. Some insulating materials
deteriorate with age. As a result, dust from the insulation material may be picked up and be spread
into the ambient air of the building.
6. Installation
Please read the
RECOMMENDATIONS
section on page 4.
In addition, for optimal performance:
- To avoid heat loss in the ducts, we advise insulating them.
- The minimum cross-sections of the inlets and outlets for convection air must be respected.
- The chimney must be suitable.
- INFLAMMABLE MATERIALS:
these should not be used in the immediate vicinity of the hearth,
the hot air vents and the chimney fl ue. A safety distance of 80 cm is required at fl oor level. It
should be noted that when operating with the door open, burning embers can be thrown several
metres.
- INSULATING MATERIALS:
use «HIGH TEMPERATURE» materials such as certain types of rock
wool or ceramic fi bre
(DO NOT USE GLASS WOOL).
5.2. Natural convection
It is vital to open four hot air vents for the Phénix 1000
and at least two for the Phénix 850 and 650. These
vents must be connected to a conduit at least 50 cm
high. The top of the hearth must not be insulated.
If the hearth is positioned at least 4 cm from the
ground,
air intake is ensured by the ventilation hole under-
neath the hearth.
(A).
However, opening the lateral inlets
appreciably improves heat recuperation.
If the hearth is place level with the ground (less than 4
cm above), the 4 air intakes must be opened.
For pre-
ference use the lateral intakes
(B).
A passage of ± 700 cm² (for 4 connected vents without
fi lter), and ± 450 cm² (for 2 connected
vents without fi lter) should be allowed in the brickwork for the entry of convection air into the
hearth.
