Commissioning the Boiler

1. Reference should be made to BS 5449 Section 5 when
commissioning the boiler.
2. Flush the whole system using a suitable flushing agent
(see Section 6.2) and vent the radiators. Check for
water leaks.
3. Refill the system with inhibitor following the inhibitor
manufacturer's instructions and BS 7593 Code of
Practice for Treatment of Water in Domestic Hot Water
Central Heating Systems (see Section 6.2).
4. Turn the gas supply on and purge the system according
to BS 6891.
5. Turn the gas service cock anticlockwise to the ON
position and check for gas soundness up to the gas
valve (Fig. 34).
6. Turn the boiler control knob fully clockwise to 'HIGH'
(Fig. 35) and run the system and check the boiler for
correct operation.
NOTE: The boiler is self-regulating and the gas rate will
modulate between inputs of 33.76kW and 10.2kW
dependent upon the system load. The input is factory set at
23.45kW and can be altered to 33.76kW - see section 8.8.
No adjustment of the gas valve is permissible.
7. With the system cold and all controls calling for heat
check the gas pressure at the inlet tapping of the gas
valve (Fig. 36). The pressure must be a minimum of
18.1 mbar.
