Maintenance
GENERAL
To ensure the continuing efficiency of the boiler, regularly carry out regular routine maintenance
procedures as detailed below.
IMPORTANT
If any fault is found during these procedures, shut down the boiler immediately and consult
Fulton China LLC.
NOTE
I
t is essential that regular checks are made to ensure scale build-up is not taking place within
the boiler. Such checks will ensure that water treatment being applied to the boiler water feed
is effective.
The lower hand hole doors should be removed after one month and the interior of the boiler
thoroughly examined. If scale or sludge build-up is observed, a water treatment specialist
should be consulted.
Subsequent interior examinations should be carried out on a regular basis until satisfactory
conditions are obtained. Thereafter, inspections should be carried out at six monthly intervals.
IMPORTANT
New gaskets must be fitted every time a hand hole door is removed, refer to Section 4.5 for
fitting procedures.
WEEKLY
WARNING
All steam pipework, valves and fittings will be very hot. Do not operate the safety valve
without protection.
Check the hand holes and man holes for signs of leakage. This is particularly important when the
boiler is started from new or when gaskets have been replaced (refer to the Section for fitting
procedures for new gaskets). Corrective action taken as soon as a leak occurs can prevent costly
repairs later.
Check for signs of leaks on all valves and fittings and take the appropriate action.
Test all the boiler water level functions by evaporation, e.g. switch off the boiler feed pump-see
Starting the Burner.
Carry out routine maintenance checks on the burner as recommended by the manufacturer’s
Installation and Maintenance instructions.
Check the flame failure controls by removing the burner flame sensor from its plug-in connection on
the side of the burner and covering the detection window to exclude all light. The burner control
should immediately go to a lockout flame failure condition and will require manual resetting. Clean the
flame sensor before replacing it.

(a) Ensure that the following valves are SHUT:
The main steam stop valve
The feedwater isolating valve

(b) Ensure that the power supply to the boiler is switched OFF.
CAUTION

Always use protective clothes and extreme caution when working on a hot boiler.
(c) Empty the boiler. It will be necessary to allow air into the boiler before it will drain via the main
blowdown valve.
(d) Remove the hand hole and manhole doors and thoroughly inspect the internal surfaces of the
boiler, paying particular attention to the junction of the tubes with the front tube plate and the
