should this trial run not prove satisfactory for reasons of the oil flow or the proportions between the fuel and
the combustion air, the oil flow is to be adjusted to the viscosity of the oil and/or the available flue draught or,
if necessary, other more far-reaching adjustments made in the oil control itself. The measures to be taken in
this case are described under «Oil Flow Adjustment».
Annual Maintenance
6. The catalyzer and support ring should be removed from the burner and lightly brushed to remove soot.
Inspect both for damage and replace as necessary.
7. The flue should be examinated for evidence of soot and where this is evident the flue should be swept.
Inspect all flue joints and re-seal where necessary.
8. Vacuum stove to remove all soot and debris.
9. Remove the drip tray drip tray and clear of all dirt and fluff.
10. Examine the burner bowl. Gently remove any deposits adhering to both the sides, bottom and fuel inlet.
11. Clean the glass using only vinegar and water. Replace if damaged.
12. Examine all gasketing and replace where necessary.
13. Inspect the door, hinge and locking mechanism for damage.
14. Examine the stove body for damage.
15. Examine the carburator and control knob extension for wear or damage.
16. The oil storage tank should be examinated for leakage, the filter removed and examined for evidence of
contamination before being cleaned or replaced.
17. The oil supply pipe line and any valves and filters should be examined and cleaned or replaced as
necessary.
18. Examine the oil valve and fittings for evidence of leaking.
19. The catalyser should be examined for signs of deterioration and black carbon, which indicates poor flue
draft. The red oxidation must not be cleaned off as this aids efficient burning at low settings.
20. The catalyser and support ring should be reassembled, the burner lit and the stove and flue allowed to
reach operating temperature.
21. Measure and record the draft reading at both low and high fire and make adjustments to the draft stabilizer
as necessary.
22. All remotely operated thermostats and timers systems should be verified as working correctly.
23. If the operation of the appliance is suspect follow and complete the commissioning instructions.
