8 COMMISSIONING
8.1 Putting into operation
The system should be thoroughly flushed prior to connecting the boiler and in accor-
dance with BS 7593 (1992).
Note:
The boiler is suitable for both natural gas and propane. It is supplied as standard
set for natural gas, therfore the following procedure must be carried out before the
boiler is fired and commissioned on propane. Fit the propane restrictor (Broag option)
and adjust the boiler parameters in accordance with the instructions supplied with the
propane conversion kit (also
use Table 12
checking boiler combustion for propane)
Attention: if the boiler is to be used on LPG, an LPG conversion kit is required
to be fitted before firing (Broag option)
1. Isolate the power supply to the boiler,
2. Remove the front panel (remove two screws at the bottom of the panel, pull the
bottom of the panel forward and lift off the top),
3. Check the gas connection for soundness, purge and leave the isolation valve in
the open position,
4. Check the electrical connections including earth,
5. Check the automatic vent is functioning and has vented the boiler,
6. Ensure that all boiler isolation valves are open,
7. Ensure that the boiler and system is full of water and pressurised to 1 bar,
8. Check the built-in circulation pump. Ensure that the impellor is free (remove the
large headed screw in the pump head end and using a screwdriver spin the impel-
lorshaft) this will vent the pump at the same time.
Attention:
pump is mounted above the controls electrics-
avoid getting water
into the electronics during the venting process.
9. Vent the installation,
10. Remove the siphon assembly, fill with clean water and replace siphon,
Attention:
this is vital as the boiler must not be operated with an empty siphon.
11. Check the flue connection,
12. Turn on the power supply to the boiler,
13. Set all controls to heat demand,
14. The boiler will now go into operation. The operational progress is shown via the
‘code’
window,
see Par. 9.2.4
,
15. The combi boiler will fire in the domestic hot water mode first to satisfy the plate
heat exchanger temperature and then it will change over to heating.
If a system boiler is used in conjunction with our kit No1 then the boiler will oper-
ate in the domestic hot water priority mode and will have to satisfy this before
changing over to heating. If other controls have been used then please refer to the
manufactures user instructions.
