COMMISSIONING
Although all burners are tested before despatch,
individual site conditions
—such as oil supply pressures
and deviations in the draught
—mean that the burner
will require adjustment after installation to achieve
optimal performance. As such, the boiler
must
be
commissioned
by
qualified
engineer,
preferably
OFTEC-trained and registered. See the burner setup
leaflet for further information.
It is the responsibility of the installation engineer to
ensure the boiler is commissioned. Failure to do so will
invalidate the guarantee and any extended warranty.
Procedure
Switch off the electrical supply to the boiler.
Ensure the boiler is full of water and that all
isolation valves are open.
Remove the combustion chamber access cover
and check the baffle positions (
figs 29
&
30
).
For single-pipe oil supplies, disconnect the supply
line from the burner. Open the shut-off valve and
run a small quantity of oil into a container to ensure
it is clean and free of air. Reconnect the oil supply.
Check that the programmer is in the
ON
position
and that any thermostats are calling for heat.
Switch on the electrical supply to the boiler, which
should now fire.
Note:
upon first firing, the burner may lockout due
to the retention of air in the oil pump. Should this
occur, wait for one minute before pressing the
reset button. Should the burner lockout again, the
air can be bled from the oil pump via the pressure
gauge connection.
Start and stop the burner several times. When the
flame cuts off sharply, this indicates that the
remaining air has been dispersed.
Set the pump pressure to the correct level. Run the
boiler for 15 minutes and measure CO
2
levels at
the flue gas sample port (
page 28
). Compare the
readings with those given in the burner setup
leaflet and if necessary adjust the intake of air into
the burner.
Check
the
smoke
number
and
flue
gas
temperature.
If the boiler is not going to be put to immediate use,
isolate the oil and electrical supplies. If the boiler is
not going to be run during freezing conditions, the
system should be drained of water.
Handing over
After completing the boiler installation, the engineer
should check the system to ensure it is satisfactory and
works according to these instructions. The use of the
boiler
and
other
system
controls
should
be
demonstrated to the end user.
All instructions should be handed to the user for
retention. Advice should be given on the requirement
for an annual service. For householder reference, the
form on
page 35
should be completed.
A CD/10 installation completion form (or non-OFTEC
equivalent) should be completed and a copy left with
the end-user. The registration card should be
completed in full and returned to TR Engineering.
Failure to do so may delay any subsequent warranty
work.
All installations must be registered with the local
authority's Building Control, either through OFTEC or
directly through Building Control.
This is a legal
requirement
. After registration, the local council will
issue a Works Notification Certificate.
SERVICING
To maintain the boiler's high thermal efficiency
—and to
ensure continued, reliable operation
—the boiler
must
be serviced annually by a qualified engineer, preferably
OFTEC-trained and registered. Any electrical work
should be carried out by a suitably qualified engineer.
A CD/11 commissioning form (or non-OFTEC
equivalent) should be completed and a copy left with
the end-user. The CD/11 enables the engineer to
demonstrate compliance with building, health and
safety, and efficiency requirements.
If the boiler provides central heating and hot water all
year round, the best time for the annual service is just
before the start of the heating season.
Before starting the service, review the health and safety
information on
page ii
.
Pre-service checks
Ensure the air inlets on the flue terminal are clear.
Ensure the external controls are working.
Ensure the ventilation openings are clear and
adequate for the size of the boiler (
pages 10
–11
).
Ensure all water and oil connections are secure.
Inspect the flexible oil lines; replace if necessary.
