9.0 Commissioning & Servicing
9.1 Commissioning
Note: It is the responsibility of the installer to ensure that the boiler is properly
commissioned by an OFTEC trained and registered technician. Failure to do
so WILL invalidate ALL warranties.
Before firing ensure that all the baffles are in place, as they may have been displaced
during transit; Refer to the General Information section. Switch the boiler on,
ensuring all controls are calling for heat.
The oil pump pressure must be checked by fitting a pressure gauge to the pump
pressure port. If necessary the pressure should be adjusted until it corresponds with
the value in the Technical Data section for the required output. Using a smoke pump,
check the smoke number. It should be zero.
Using a flue gas analyser, check the CO2 content and flue gas temperature once
the boiler is hot. Testing while the boiler is still relatively cold gives inaccurate results
and leads to incorrect adjustments being made.
Where a balanced flue has been fitted ensure the air duct connecting the flue and
burner has been properly connected before commissioning.
To comply with the building regulations OFTEC form CD should be completed
and a copy left with the householder.
9.2 Servicing
9.2.1 General Requirements
It is recommended that the appliance is serviced annually by a Warmflow or an
OFTEC registered service technician in accordance with the recommendations
laid out in OFTEC’s technical information book 2 – ‘Pressure Jet Appliances
– Commissioning Requirements for Technicians’.
Additionally, when servicing, special attention should be paid to the condition of the
oil nozzle, flexible oil line, fuel filter, door insulation, sealing rope and secondary heat
exchanger door seal. If found to be defective they must be replaced.
The system corrosion inhibitor level must be checked (instant on-site test kits are
available from inhibitor manufacturers) and additional inhibitor must be added if the
system is found to be under-dosed. Refer to the inhibitor manufacturer for further
guidance.
Note: All product warranties will be invalidated if the appliance is not serviced
annually by a Warmflow or OFTEC trained and registered technician.
