All steam pipework, valves and fittings will be very hot.
1.
Visually inspect for signs of leakage:
a)
Steam and feedwater pipework.
b)
Valves and fittings.
c)
Handholes
If leakage is evident, the gasket needs replacing.
If leaks are suspect
ed, shut down and evacuate the system to atmospheric
pressure before attempting to repair the leaks.
2.
Low Water Level Check (see Section 6.4.2).
3.
Blowdown the Boiler (see Section6.5.1).
Note: If th
e boiler is being operated automatically on a time clock, the blowdown may be done once during the
working day and once at the end of the day when generating 10 psig or less, providing this is sufficient to
control the TDS level within limits.
4.
Blowdown the Water Level Gauge (sight glass), (see Section6.5.2).
Ensure the fittings around the steam safety valve(s) are secure.
The safety valve will be very hot, do not operate the safety valve without protection.
5.
Ensure that the pipe from the safety valve outlet is not damaged and that it continues to a safe
bl
owdown point.
6.
Feedwater Pump Test (see Section 6.4.1).
7.
Evaporation Check (see Section 6.4.3).
8.
Flame Failure check (remove the UV cell to lock out burner).
