COMMISSIONING
The commissioning and first firing of the boiler must only be
carried out by a competent person.
To gain access to the inside of the boiler undo screw securing front
panel at the boiler bottom, remove front panel by pulling forwards,
lifting it up and off. Note – upper edge of front casing is fixed to the
boiler by means of 2 pins.
Gas installation
It is recommended that any air is purged from the supply at the gas
inlet test point on the gas valve, see diagram 13.
1
- Inlet test point
2
- Outlet test point
Filling the system
•
Check that the gas meter tap is closed.
•
Conect boiler to electrical supply.
•
Place switch (1) diagram 1 to possition “I”. F0 is displayed and
the pump runs for about one minute.
•
Press the BAR button, see diagram 1. Value of system pressure (0.0) is displayed
and LED (2) – see diagram 1 – lights.
Note:
The pressure is displayed for about 25 sec. After this time the display comes
back to the standby mode. The pressure can be displayed after pressing Bar push button again.
•
Open isolating valves (
A
,
E
and
D
) see diagram 6.
•
Undo, but not remove, cap on automatic air vent on the top of the pump.
•
Fill system by opening system filling loop until a pressure of between 1 and 2 bar is shown on the display.
•
Bleed each radiator until a continuous jet of water is obtained.
•
Do not retighten automatic air vent cap.
•
Open various hot water taps to bleed hot water circuit.
•
Make sure that pressure is between 1 and 2 bar. Re-pressure as necessary.
Important:
When venting air from boiler, do not touch the schrader valve on the expansion vessel, it is NOT a
vent.
Starting the boiler
Before starting the boiler check that:
- The gas meter tap is open.
- The boiler gas service cock is open.
- The water isolating cocks are open.
- The boiler is connected to the electrical supply.
First starting up
•
Place main switch (1) diagram 1 to position “I”.
•
Set maximum heating water temperature (85°C), as described in
‘Users Instructions’
and check that any
external controls, if fitted, are calling for heat.
•
Allow the temperature to rise to the maximum value, with all radiator valves open. Air contained in the water
of central heating system will be automatically released through the automatic air vent. Air trapped at the
hightest point of the system must be released by bleeding the radiators.
On reaching maximum temperature, the boiler should be turned off and the system drained as rapidly as
possible whilst still hot.
•
Refill system to a pressure at least of 1 bar and vent as before.
•
Restart boiler and operate until a maximum temperature is reached. Shut down boiler and vent air from
heating system. If necessary, top up heating system and make sure that a pressure at least of 1 bar is
indicated on the display when system is COLD.
Gas pressures
•
Shut down boiler.
•
Undo screw on gas inlet test point ‘1’ on gas valve, see diagram 13.
•
Connect a suitable pressure gauge.
•
Start boiler as described in
‘Users Instructions’.
