Boiler Start-Up (From Cold) All Models; Boiler Start-Up Following Short Term Shut-Down - FULTON VSRT Series Installation, Operation And Maintenance Manual

Fulton Ltd
5.5 BOILER START-UP (FROM COLD)
1. Fill the boiler (see Section 5.3 - Filling the Boiler).
2. Ensure the main steam isolating valve is SHUT.
3. Open all the valves in the gas train. It is assumed that the fuel supply lines have been purged
prior to attempting to start the boiler/burner.
4. Switch the Pump and Boiler switches to the ON position.
The Low Water audible alarm will sound, the Low Water Limiter lights will illuminate.
5. Press the Common Alarm Reset button for two seconds maximum. The alarms will
stop, and the alarm lights will extinguish.
Reset high pressure switch.
The burner start sequence will commence.
6. After a maximum of two minutes the burner should be firing, and the Main Gas light
should illuminate.
The system should be raised to temperature slowly to allow for expansion and to avoid thermal shock
When the boiler has achieved the required (set) pressure, the main steam isolating valve
should be slowly opened allowing steam to enter the system distribution pipework.
This can be achieved by one of two methods:
a) Partially open the main steam valve and allow the system to heat up slowly (minimum
15 minutes) before fully opening the main steam valve.
b) Open the main steam valve when starting the boiler, allowing the boiler and system to heat
up together.
Note: This can lead to water logging of the steam lines until full pressure is achieved.
If fitted, TDS Panel Mounted Controllers (BC3250) must be reset after any break in electrical supply to the unit.
Note: Before leaving the boiler unattended, the daily operating tests (see Section 6.8.1) should be carried out to
check the functions of all the safety interlocks.
5.5.1

BOILER START-UP FOLLOWING SHORT TERM SHUT-DOWN

If the boiler has been shut down for a short period of time (6 hours or less), it can be switched
on and allowed to cycle to normal firing rates as the low thermal expansion of the boiler
pressure vessel allows this. However, if the boiler has been shut down for extended periods of
time, it should be brought up to normal operating temperature and pressure in a controlled
manner.
