7.1 Inspection and service - 18/25 Regular shown
Routine servicing
To maintain efficient boiler operation, the following should be carried
out at least once a year, carry out a pre-service check and note any
operational faults.
Service requirements
See the following instructions for detail of some of the service
requirements:
▶ Check that the safety and regulation devices (3 bar safety valve, air
bleed, etc.) are operating properly.
▶ Also check that neither the installation nor the appliance present any
water or fuel leaks, (leaks may produce a safety risk and shorten the
life-span).
▶ Clean or replace all oil filters.
▶ When it is frequently necessary to add water to maintain pressure in
the installation, even though no leaks have been discovered, perform
an expansion vessel check.
▶ Check that the condensate system is not obstructed, clean and refill
the condensate trap as necessary.
▶ Check the condition of the various seals (burner flange, burner door,
flue outlet, etc.).
▶ Check and clean the burner.
▶ Replace the burner nozzle and flexible oil pipe/s.
▶ Check and clean the primary and secondary baffles.
▶ Check and clean the heat exchangers surfaces.
▶ Check the combustion chamber access door insulation board.
▶ Check that the flue system is unobstructed and clean as necessary.
Sealed system only
The PRV is a safety device and must be checked for correct operation.
The expansion vessel pressure must also be checked and adjusted if
required.
Oil supply system and tank
▶ The oil pipeline, filters, fire valve and tank should be inspected and
maintained in accordance with OFTEC regulations.
Fire valve
▶ Check that the oil supply pipe has a fire valve fitted externally to the
building with the fire valve sensor located within the appliance case.
A fire valve sensor clip is provided for this purpose on the support bar
between the side panels.
The fire valve should be rated at 85 °C or above to avoid nuisance cut
outs.
Pre-service checks
▶ Release the latches [3] at the base of the front panel [2] using the
key provided and lift the panel and pull towards you to remove. Store
the panel safely away from the working area.
▶ Operate the appliance and system and note any faults which may
need to be corrected during the service.
▶ Switch into service mode at switch [1].
Fig. 58 Access to internal components
▶ Unplug burner lead [1]from control box.
▶ Unscrew to loosen the retaining ring [4] that secures the flexible air
supply tube [3] to the burner and remove from the burner.
▶ Undo and remove the retaining nut [2] on the top of the burner.The
burner can now be removed from the heat exchanger. Store the
burner and retainer nut safely away from the boiler.
