MAINTENANCE - 4
21. Using a wire brush, clean the internal surfaces of the furnace and the face of the front tube
plate. Pay particular attention to the tube ligaments (the spaces between adjacent tubes).
22. Inspect the tube ends for any signs of splitting or burning.
These are symptoms of gas reburning in the tube ends as a result of poor combustion, e.g.
carbon monoxide carry-over. If the tube ends exhibit these signs, consult Fulton Ltd.
Ensure that the rear smoke box drain connections are clean and free from deposits.
This is particularly important on oil fired boilers because of the acidic nature of the condensate formed.
23. Clean out the rear smoke boxes to remove the deposits brushed through from the tubes.
24. Inspect the rear smoke box door seals for deterioration and replace if necessary.
25. Remove the access panel from the economiser (where fitted), inspect the finned tubes of the
economiser for clogging or blocking, clean as required. Extreme care should be taken not to
damage or distort the fins. Maintenance instructions for control and safety devices fitted to the
economiser system should be fully observed.
26. Refit the economiser access panel.
27. Close the boiler front access door by reversing the opening procedure.
i) Close the boiler door.
ii) Tighten the four retaining nuts (the two on the hinge side by two complete turns) (see
Section 4.8).
iii) Reconnect gas supply (authorised personnel only) to the gas train.
iv) Reconnect oil supply to the oil lines.
28. Drain and flush the feedwater/hotwell tank, clean any filters and the strainer in the feed line
before the pump.
29. Drain and flush out the blowdown separator.
30. Carry out routine maintenance to the burner as detailed in the manufacturers Installation and
Maintenance instructions.
Note: Depending upon the mode of operation, it may be found that the six monthly interval can be extended,
possibly to an annual service. It is strongly recommended, however, that the interval should be 6 months from
initial start up until such times as a 'pattern of use' and the condition of the boiler after a typical 6 months can be
established.
