Boiler check:
u
Baffles should be checked as they may have been
disturbed during transport.
u
Check that the condensate trap is fitted securely,
primed with water and piped out into a suitable drain.
It is easier to check the trap when the boiler door is
removed.
u
The boiler door should be refitted, complete with
graphite seal and then tightened.
Flue check:
u
The flue must be fitted correctly, with a fall back to
the boiler. Note: internal fall of 2.5˚ within the flue.
u
For concentric balanced flue:
- the cone supplied should be inserted in to the end
of the flue;
- the wall plate should be fitted with an opening
for air under the flue;
- check that the flue guard is fitted.
u
When installing a Systempac or Slimline Systempac,
the 90˚ bend should be fitted pointing up.
Boiler set-up:
u
For burner set-up, see next page.
u
Set the air to what is required for the nozzle size +. 5
on the dial - example: the factory setting for a Firebird
26kW has a Danfoss .65 80° ES nozzle with a pump
pressure of 9 bar and air at 2.5. The final air setting to
suit the boiler set up will be determined by using a
flue gas analyser.
u
Turn on the oil supply and switch on power to the
boiler.
u
Check all connections for possible leaks.
u
Check thermostat operation and set desired
temperature on completion.
u
Use a smoke gun to check clean combustion.
Flue gas analysis and fine tuning of burner:
u
Ensure flue gas is over 50˚C when setting CO
2.
u
Allow the boiler to run for a period of time before fine
tuning to the Firebird settings.
u
Fine tuning of the burner should take place once the
recommended oil pressure value has been obtained.
Burner air should then be adjusted to achieve the
desired CO
2
setting.
u
Print off a copy of the flue analysis and attach to the
boiler passport.
u
Make sure the flue gas analysis plug is replaced
correctly into the flue when finished the flue analysis.

The householder should receive:
• A clear and concise demonstration of the boiler
operation and any system controls.
• This manual, the burner manufacturer’s manual
and any other instructions.
• OFTEC forms CD10 and CD11.
• The boiler passport.
The householder should be advised to:
• Service the boiler annually and to ensure that the
service records in the boiler passport are completed.
• Read the terms and conditions of warranty.
• Keep all boiler documentation in a safe place.
a commissioning record should be completed
and a copy retained by the engineer.
this can be found in the Boiler Passport.
