NOTICE
The boiler manufacturer cannot be held responsible for
atmospheric conditions when siting flue terminals.
CAUTION
Once the flue system has been installed and the appliance
commissioned, the installer should observe the plume
direction. Particular attention should be drawn to plume
vapour reentering the gas boiler via the air intake. If this
occurs, it is highly possible the flue is fitted with a negative
pressure area and therefore a plume management kit
MUST be fitted.
9.9.7
Insulation of the gas exhaust and air
intake
Condensation may occur on the outside of the pipe material when
the material temperature is low and the environment temperature is
high with a high humidity. Use 10 mm damp-proof insulation material
when there is a risk of condensation.
9.9.8
Fitting a horizontal flue system
The 60/100 mm horizontal flue system may be extended up to a
maximum length as specified in the table indicating the maximum
pipe lengths. Calculate the equivalent length according to the
specifications in this manual.
CAUTION
Read the installation manuals of the field supplied parts.
The horizontal flue MUST be installed under a 3° fall towards the
boiler (50 mm per metre) and MUST be supported with a minimum
of 1 bracket at each meter length. Best recommended position of the
bracket is just before the joint.
INFORMATION
Flexible flue gas lines may NOT be used in horizontal
connection sections.
9.9.9
Fitting a vertical flue system
A vertical 60/100 mm flue kit is also available. By using additional
components available from your boiler supplier, the kit can be
extended up to a maximum length as specified in the table indicating
the maximum pipe lengths (excluding the initial boiler connection).
CAUTION
Read the installation manuals of the field supplied parts.
9.9.10
Plume management kit
See the local and national regulations.
Especially for UK:
The plume management kit comprises of a 710 mm horizontal
section elbow to connect the 500 mm vertical condensing tube,
which has a horizontal or vertical terminal dependant on your
requirements. The maximum length of the horizontal flue including
the terminal but excluding the initial elbow from the boiler and
500 mm vertical condensing tube is 7 m.
NOTICE
For each additional 90° elbow used the maximum flue
length MUST be reduced by 1.5 m whilst the use of 2× 45°
bends warrants a reduction of 2 m.
The horizontal part of the flue MUST be installed under a 3° fall
towards the boiler (5 mm per m) and MUST be supported with a
minimum of 1 bracket at each 1 m length. Best recommended
position of the bracket is just before the joint.
CAUTION
▪ Sealing rings should ONLY be moisturized with water
before use. Do NOT use soap or other detergents.
▪ When installing flues in voids, make sure that they are
connected and fixed correctly. If in an existing situation
a visual inspection is NOT possible, the boiler must
NOT be commissioned and remain disconnected from
the gas supply until suitable access has been realised.
▪ Make sure to follow the manufacturer’s instructions
regarding maximum length of the flue system, the
appropriate flue material, correct jointing methods and
the maximum distance between flue support.
▪ Make sure that all joints and seams are gastight and
watertight.
▪ Make sure that the flue system has a uniform gradient
back to the boiler.
