OPERATION - 4
4.7 BOILER START-UP (FROM COLD) ALL MODELS
CAUTION
The system should be raised to temperature slowly to allow for expansion and to avoid thermal shock
and water hammer.
!
1. Fill the boiler (see Section
4.5 - Filling The Boiler
).
2. Ensure the main steam isolating valve is SHUT.
3. Open all the valves in the gas train/oil supply. It is assumed that the fuel supply lines have
been purged prior to attempting to start the boiler/burner.
CAUTION
Failure to open the oil supply line will damage the oil pump.
A pump damaged under these circumstances will not be replaced by warranty.
!
4. (DUAL FUEL ONLY) CLOSE alternative fuel supply valves with the proof of closure microswitch.
5. Switch the Pump and Boiler switches to the ON position.
The Low Water audible alarm will sound, the Low Water Limiter lights will illuminate.
6. 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.
7. After a maximum of two minutes the burner should be firing, and the Main Gas light should
illuminate.
8. 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 (BC3150) must be reset after any break in electrical supply to the unit.
Note:
Before leaving the boiler unattended, the daily operating tests (see
Section 5.8.1
) should be carried out to
check the functions of all the safety interlocks.
