INSTALLATION
3.2.2 - Standard natural draft configuration
(B
23
) (flue operating at negative pres-
sure)
Definition: Lining of an existing chimney flue by a
sealed STAINLESS STEEL corrugated flue of
Ø
125.
- The termination is specific to this configuration
and the outlet must be above the roof (comply
with the specification of the decree of 22 October
1969),
- Do not use the hose for a horizontal assem-
bly: condensate may be retained.
- Use the optional PP accessories (mandatory
bleed T-bracket, etc.) for the stainless steel con
-
duit connection to the boiler,
- Fit a siphon (5) with a minimum 80 mm seal be-
tween the bleed T-bracket and the waste water
pipe,
- Ventilation for the flue (rep. 8) and the heating
system
(section 2 - chapter IV - INSTALLA-
TION) must be provided.
- If the boiler is installed in premises that have me-
chanical air extraction, ensure that this does not
cause negative pressure.
- The premises must never be fitted with other ap-
pliances using natural draft to operate.
- The air is sucked in by the burner directly from the
room in which the boiler is fitted.
- The burner must be equipped with the air damper
(item no. 2) in order to prevent heat losses due to
draft.
