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

IMPORTANT
Ensure that the rear smoke box drain connections are clean and free from deposits.
This is particularly important on oil red boilers because of the acidic nature of the condensate formed.

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.
