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. Complete the label supplied with the inhibitor and
attach to the inside of the boiler case. Detail of system
treatment should be added for future reference.
5. Turn the gas supply on and purge according to in GB

NOTE: The boiler is self-regulating and the gas
rate will modulate between inputs of 33.76kW and
10.3kW dependent upon the system load. The
input is factory set at 24.90kW and can be altered
to 33.76kW - see section 8.8. No adjustment of
the gas valve is permissible.
8. 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 (Working Pressure). Check that the gas rate
is no greater than 3.3m
WARNING: The PCB Control and Fan
Assembly is 325 Vdc. Isolate at supply
before access.
