4 COMMISSIONING, USE and MAINTENANCE
COMMISSIONING INSTRUCTIONS
A Commissioning checklist is included
in this manual and must be completed
by the engineer at the time of commis-
sioning.
General
Please note: the combustion for this
appliance has been checked, adjusted
and preset at the factory for operation
on the gas type defined on the appli-
ance data plate. However, it is advisable
to check for correct combustion having
first checked the following.
– That the boiler has been installed in
accordance with these instructions
– The integrity of the flue system and
the flue seals
– That PAR 9 has been set according to
the calculated flue head losses(single
boilers)
– That PAR 1 is set correctly for boilers
connected to cascade flues
– The integrity of the boiler combustion
circuit
Proceed to put the boiler into operation
as follows:
1. Check the operational (work-
ing) gas inlet pressure.
Set up the boiler(s) to operate
at maximum rate as described
in 4.5.1 (chimney sweep)
With the boiler operating
in the maximum rate condi-
tion check that the operational
(working) gas pressure at the
inlet gas pressure test point (see
fig 16 item 1) complies with the
requirements of table 1.3.
Ensure that this inlet pressure
can be obtained with all other
gas appliances in the property
working.
2. Competence to carry out the
check of combustion perfor-
mance
- The person carrying out a
combustion measurement
should have been assessed as
competent in the use of a flue
gas analyser and the interpreta-
tion of the results.
- The flue gas analyser used
should be one meeting the
requirements of BS7927 or
BS-EN50379-3 and be calibrated
i accordance with the analyser
manufacturers requirements,
and
- Competence can be demon-
strated by satisfactory comple-
tion of the CPA1 ACS assess-
ment, which covers the use of
electronic portable gas analys-
ers in accordance with BS 7967,
parts 1 to 4.
3. Combustion check
Connect the flue gas analyser to
the flue gas sampling point as
shown in the diagram (fig. 15/a).
Procedure for checking the
combustion. Operate the boilers
in “Chimney Sweep “mode as
described in section 4.5.1 and
record the measurements from
the flue gas analyser on both
minimum and maximum output.
Compare the results to the fol-
lowing:
CO less than 200ppm
CO2 between 8.9% and 9.7% nat-
ural gas, and 9.9% and 10.5%
LPG. Ratio less than 0.004.
If the combustion reading is
greater than the acceptable
value AND the integrity of the
complete flue system, combus-
tion circuit seals have been veri-
fied, AND the gas inlet pressure
has been verified, AND the boil-
er parameter settings are cor-
rect, proceed as shown in 4.2.2.
Any adjustments should be done
in small steps and adjustments
of no more than 1/8th of a turn
should be made, waiting at least
1 minute between adjustments
to allow the settings to stabilise.
Using the CO2 reading, adjust-
ments should be made to the
“OFF-SET” screw (6 fig 16) if
it is incorrect at the minimum
output, or to the “SHUTTER” (5
fig16) if it incorrect at the maxi-
mum output.
If an acceptable setting level
cannot be achieved, re-confirm
that the integrity of the flue
system, combustion circuit and
working gas supply pressure.
