Establish the heating connections in accordance with
the applicable standards.
Purge the gas line before start-up.
Check whether the connections (→ Page 16) are leaktight.
Follow the instructions listed here and observe directives
and local regulations on condensate discharge.
Use PVC or another material that is suitable for draining
the non-neutralised condensate.
If it cannot be guaranteed that the materials the drain
lines are made from are suitable, install a system for
neutralising the condensate.
Ensure that the connection between the condensate
drain pipework and the drain hose is not air-tight.
▶
During installation remove all burs from inside of cut pipe
work and avoid excessive adhesive which may trap small
pockets of water close to the pipe wall which can freeze
and build into a larger ice plug.

Caution.
The use of unsuitable heating water may
cause aluminium corrosion and a resulting lack of leak-tightness.
In contrast to steel, grey cast iron or copper,
for example, aluminium reacts with alkaline
heating water (pH value > 8.5) to produce
substantial corrosion.
▶
When using aluminium, make sure that
the pH value of the heating water is
between 6.5 and a maximum of 8.5.
Caution.
Risk of material damage if the heating

Appendix
H.2
Text from BS 5440-1 on fan-supported flue gas pipes
BS 5440–1: It is recommended that the fanned flue gas system terminal is positioned as follows:
–
–
–
–
At least 2 m from an opening in the building directly opposite, and
So that the combustion products are not discharged directly across a property boundary.
Dimensions D, E, F and G: These clearances may be reduced to 25 mm without affecting the performance of the boiler.
In order to ensure that the condensate vapour plume does not damage adjacent surfaces, the terminal should be extended as shown.
Dimension H: This clearance may be reduced to 25 mm without adversely affecting the performance of the boiler. However, in order to ensure that the condensate vapour plume does not damage adjacent surfaces, a clearance of 300 mm is
preferred. For IE, recommendations are given in the current issue of the IS 813.

PRIOR TO CO AND COMBUSTION RATIO CHECK
The boiler manufacturer’s installation instructions should have been followed, gas type verified and gas
supply pressure/rate checked as required prior to commissioning.
As part of the installation process, especially where a flue has been fitted by persons other than the
boiler installer, visually check the integrity of the whole flue system to confirm that all components are
correctly assembled, fixed and supported. Check that manufacturer’s max. flue lengths have not been
exceeded and all guidance has been followed (e.g. Gas Safe Technical Bulletin TB008).
The flue gas analyser should be of the correct type, as specified by BS 7967
Prior to its use, the flue gas analyser should have been maintained and calibrated as specified by the
manufacturer. The installer must have the relevant competence for use of the analyser.
Check and zero the analyser IN FRESH AIR as per analyser manufacturer’s instructions.
NOTE
THE AIR GAS RATIO VALVE IS FACTORY
SET AND MUST NOT BE ADJUSTED
DURING COMMISSIONING UNLESS THIS
ACTION IS RECOMMENDED FOLLOWING
CONTACT WITH THE MANUFACTURER.
If any such adjustment is recommended and
further checking of the boiler is required the
installer/service engineer must be competent
to carry out this work and to use the flue gas
analyser accordingly.
If the boiler requires conversion to operate with
a different gas family (e.g. conversion from
natural gas to LPG) separate guidance will be
provided by the boiler manufacturer
SET BOILER TO MAXIMUM RATE
In accordance with boiler instructions, set boiler to operate at max. rate
(full load condition). Allow sufficient time for combustion to stabilise.
NOTE - Do not insert analyser probe during this period to avoid
possible “flooding” of sensor.
CARRY OUT FLUE INTEGRITY CHECK USING ANALYSER
Insert analyser probe into air inlet test point and allow readings to stabilise.
NOTE - where no air inlet test point is provided then a flue integrity check
with the analyser is not possible. The installer should verify that flue
integrity has been visually checked in accordance with the “Prior to
CO and combustion ratio check” box above before proceeding to the
“Check CO and combustion ratio at maximum rate” stage below.
VERIFY FLUE INTEGRITY
Analyser readings indicate that combustion products
and inlet air must be mixing. Further investigation of
the flue is therefore required.
Check that flue components are assembled, fixed
and supported as per boiler/flue manufacturer’s
instructions.
Check that flue and flue terminal are not obstructed.

TURN OFF APPLIANCE AND CALL
MANUFACTURER’S TECHNICAL HELPLINE
FOR ADVICE.
THE APPLIANCE MUST NOT BE
COMMISSIONED UNTIL PROBLEMS ARE
IDENTIFIED AND RESOLVED.
CHECK CO AND COMBUSTION RATIO AT MAX. RATE
With boiler still set at maximum rate, insert analyser probe into flue gas
sampling point. Allow readings to stabilise before recording.
NOTE - If no flue gas sampling point is present and the correct procedure is
not specified in the manual, consult boiler manufacturer for guidance.
NO
Check all seals around the appliance burner,
internal flue seals, door and case seals.
Rectify where necessary.

YES
SET BOILER TO MINIMUM RATE
In accordance with boiler instructions, set boiler to operate at minimum rate (to
minimum load condition). Allow sufficient time for combustion to stabilise.
NOTE - If manufacturer’s instructions do not specify how to set boiler to minimum
rate contact Technical Helpline for advice.
NO
CHECK CO AND COMBUSTION RATIO AT MINIMUM RATE
With boiler still set at minimum rate, insert analyser probe into flue gas sampling
point. Allow readings to stabilise before recording.
NOTE - If no flue gas sampling point is present and the correct procedure is not
specified in the manual, consult boiler manufacturer for guidance.
TURN OFF APPLIANCE AND CALL
MANUFACTURER’S TECHNICAL HELPLINE
FOR ADVICE.
THE APPLIANCE MUST NOT BE
COMMISSIONED UNTIL PROBLEMS ARE
IDENTIFIED AND RESOLVED. IF
COMMISSIONING CANNOT BE FULLY
COMPLETED, THE APPLIANCE MUST BE
DISCONNECTED FROM THE GAS SUPPLY IN
ACCORDANCE WITH THE GSIUR.
NOTE: Check and record CO and combustion ratio
at both max. and min. rate before contacting the
manufacturer.

NO
Is
CO less than
350ppm and
CO/CO2 ratio
