Fluing - IDEAL Harrier GTS 5 Installation And Servicing

10 FLUING

According to the output, the difference between the temperature of
the flue gas and the ambient temperature can be as low as 160
The installer will have to respect all of the usual precautions (dilution
- piping - T for removal of condensation) in order to prevent
deterioration of the chimney. The use of a draught stabiliser is also
recommended.
FLUE SIZE
Refer to applicable regulations while determining the size and height
of the flue. Please note that Harrier GTS boilers have pressurised
and sealed combustion chambers and that the pressure at the outlet
must not exceed 0 mbar.
Detailed recommendations relating to the design of flues for GAS
fired appliances are quoted in BS. 6644 and IGE/UP/10, whilst BS.
5410 Pt. 1 similarly applies to OIL fired boilers.
The table below contains the minimum dimensions of the flue
required for each boiler model in order to ensure sufficient draught
at the outlet.

11 DIMENSIONAL INFORMATION REQUIRED FOR THE FLUE CONNECTION
Connection
The connection must be made in a competent manner with
airtight pipe in a material that is resistant to hot gases from the
combustion and possible acid condensation. This pipe must
be as short as possible, be removable and without any
sudden change in its section.
The diameter must always be at least equal to that of the boiler
outlet.
