Timber framed buildings:
Where the flue system is to be fitted into a
timber framed building the guidelines laid
down in BS5440: Part 1 and IGE "Gas
Installations in Timber Frame Buildings” should
be adhered to.
IF YOU SMELL GAS:
DON'T SMOKE OR STRIKE MATCHES.

BENCHMARK:
A Benchmark check list is provided by the manufacturer at the rear of the appliance
instruction manual for the installer to complete, including their CORGI registration
number, to confirm that the boiler has been installed, commissioned and serviced
according to the manufacturer’s instructions.
IMPORTANT: The completed Benchmark check list will be required in the event of any
warranty work and may be required by the local Building Control Inspector.
FITTING & MODIFICATIONS:
Fitting the flue system may only be carried out by a competent engineer in accordance
with these instructions and the relevant Installation Regulations.
Flue systems must not be modified in any way other than as described in the fitting
instructions.
Painting of the plume management kit is not permitted.
Any misuse or unauthorised modifications to the flue or associated components could
invalidate the warranty. The manufacturer accepts no liability arising from any such
actions, excluding statutory rights.
• Flue terminals must be positioned to avoid combustion products entering into
buildings.
• The flue must be fitted and terminated in accordance with the recommendations
of BS5440 : Part 1.
• The flue must not cause an obstruction.
• Discharge from the flue outlet must not be a nuisance.
• Flue gases have a tendency to plume and in certain weather conditions a white
plume of condensation will be discharged from the flue outlet which could be
regarded as a nuisance.
• There should be no restriction preventing the clearance of combustion products
from the terminal.
• The air inlet/outlet duct and the terminal of the boiler must not be closer than 25mm
to any combustible material. Detailed recommendations on protection of combustible
materials are given in BS 5440:1
• A protective terminal guard must be fitted if the terminal is 2m or less above a
surface where people have access. The guard must be spaced equally (minimum
50mm) around the flue and fixed to the wall with plated screws.
SERVICING:
The appliance and flue system should be regularly serviced by a competent, qualified
engineer (such as British Gas or other CORGI registered personnel) using approved
spares, to help maintain the economy, safety and reliability of the appliance.
The plume management kit must be visually inspected - annually.
