FLUING
According to the output, the difference between the
temperature of the flue gas and the ambient temperature can
be as low as 160
o
C. 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.

FLUE SIZE
Refer to applicable regulations while determining the size
and height of the flue. Please note that GTE boilers have
pressurised and sealed combination 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 British Gas
Publication No. IM11, whilst BS. 5410 Pt. 1 similarly applies to
OIL fired boilers.

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.
