INSTALLATION
10 FLUING
According to the output, the difference between the temperature
of the flue gas and the ambient temperature can be as low as
160ºC. 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 Viceroy 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.
(1) : at boiler maximum input.
(2) : Boiler flow temperature: 80ºC (ambient temperature : 20ºC).

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.
