FLUE PIPE DIMENSIONS

Guideline for sizing the flue as a function of it's height:
FLUE PIPE (h)
< 4m
4m < 6m
> 6m
If this is not feasible you should contact a flue specialist.
CROSS-SECTION: the flue pipe's cross-section depends on
the height of the flue and the thermal power of the installed
cooker.
To ensure the optimal yield of our cookers we recommend
you use circular flue pipe with smooth interior lining and of
the same length all the way up.
INSULATION: flue draught pressure also depends on the dif-
ference in the temperature of the hot flue gases and that of
the air outside.
The flue pipe must be insulated to restrict absorption of heat
into the walls and therefore avoid condensation, which can
cause tarry residues. Use only suitable heat- and corrosion-re-
sistant materials conforming to building and fire-prevention
regulations. You should not use flue pipes comprising simple
or flexible metal tubes, cement tubes for vents, etc.
DEPRESSION: the optimal depression (flue draught pressu-
re) for de Manincor's cookers is 0,12 mbar.
At a depression below 0,12 mbar, the fire will burn too slowly
and form carbon residue excessive gases. If instead depres-
sion is any greater, combustion will be too fast and not tran-
smit as much heat to the boiler and heating plate, and will
require more attention.

CONNECTION TO THE FLUE PIPE

The cooker is delivered with the connection corresponding to
the flue exit chosen when ordering:
Above Fix
Rear Fix
Side Telescopic
EACH COOKER SHOULD HAVE ITS OWN FLUE PIPE. DO
NOT USE THE SAME FLUE PIPE FOR MORE THAN ONE
APPLIANCE.
THE COOKER SHOULD BE CONNECTED TO THE FLUE PIPE
AVOIDING AS FAR AS POSSIBLE ANY BENDS,
DIVERSIONS AND DOWNWARD OR HORIZONTAL
SECTIONS (IF THESE ARE UNAVOIDABLE, THE GRADIENT
SHOULD BE 2-3 CM PER METRE)
1. Pipe is too long and
on inclined plane
2. Pipe narrower than outlet hole
3. Leaky cleaning panel

Connecting pipes must be perfectly sealed to each other and
to the stove and flue pipe. These precautions must be taken:
• use a seal to avoid infiltration of air into the flue;
• the pipe must not be narrower at the end;
• the end of the pipe must not protrude into the flue.
