12 COMMISSIONING & SERVICING
12.1 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 CO
2
content and the 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.
Note: All product warranties will be invalidated if the appliance is not commissioned by a
Warmflow or OFTEC trained and registered technician and the commissioning certificate
of the OFTEC Boiler Passport completed and returned to Warmflow within 30 days from
the date of installation and 90 days from the date code stamped on the appliance.
Additionally, to comply with the building regulations, the boiler passport or OFTEC form CD11
should be completed and a copy left with the householder.
12.2 Servicing
12.2.1 General Requirements
The appliance must be 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 the 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 and details logged in the
OFTEC Boiler Passport.
