10 Commissioning

this is quite normal and it will disappear after a short period of time.

Refit the electrical controls box.

10.5 Heating System

Check that all remote controls are calling for heat.

Allow the system to reach maximum temperature and examine for water leaks. The boiler should then be turned off and the system drained off as rapidly as possible whilst still hot.

Refill the system, vent and again check for water soundness.

For sealed water systems adjust to initial design pressure. The set pointer on the pressure gauge should be set to coincide with the indicating pointer.

The overrun thermostat will keep the pump running when the boiler shuts down, so long as the temperature within the boiler is above a predetermined level.

When commissioning the system the boiler should be fired with the bypass fully closed on full service, that is, central heating and domestic hot water. The system should then be balanced, adjusting the pump and lockshield valves as necessary to achieve flow rates, refer to Section 2.4.

Having achieved a satisfactory condition, operate the boiler with the bypass closed on minimum load, normally central heating only with one radiator operating in the main living area. The valve should be opened gradually to achieve the appropriate flow rate as quoted in Section 2.4. If necessary readjust the pump.

Under NO circumstances should this valve be left in the FULLY Closed position.

10.6 Condensate Check

After 30 minutes of running, turn the boiler off and remove the inner case.

Check that there are no condensate leaks from the fan outlet/ flue elbow or fan inlet/flue hood joints. Also check for leaks from the condensate drainage system.

10.7 Operational Checks

Adjust the control thermostat and any system controls to their required settings and set “high/low” switch to “high”.

Do not attempt to adjust the thermostat calibration screw.

Operate the boiler again on full service and check that the balancing is satisfactory, making further adjustments as necessary to the system, radiator valves and bypass.

There must be no pumping over of water or entry of air at the vent above the feed and expansion cistern.

If thermostatic radiator valves are fitted care must be taken to make sure that there is an adequate flow rate through the boiler and bypass when the valves are closed. For guidance on the use of thermostatic radiator valves refer to the current issue of BS7478 and British Gas “Guidance Notes for Installation of Domestic Condensing Boilers”.

To check the operation of the flame supervision device, with the burner alight, turn gas service cock to “Off” the burner will go out. There will be one attempt to relight, indicated by a 5 second ignition phase.

Wait for 30 seconds.

Turn the gas cock to “ON” and the burner should NOT relight.

Turn the control thermostat knob to “OFF” and then “ON” again and the burner WILL now relight.

Turn “high/low” switch to “low” and observe low flame, then return switch to “high”.

Refit the outer case, see diagram 5.2, and secure the case with the screws from fittings pack.

11 User Information

11 User Information

Instruct and demonstrate the efficient and safe operation of the boiler, heating system and if fitted the domestic hot water system.

Advise the user that, like all condensing boilers this appliance will produce a plume of condensation from the flue terminal in cool weather. This is due to the high efficiency and hence low flue gas temperature of the boiler.

Show the user the position of “Lighting Instructions” - refer to Instructions for Use.

Advise the user that for summer use the “high/low” switch can be turned to “low”.

Advise the user of the precautions necessary to prevent damage to the system and building in the event of the heating system being out of use during frost and freezing conditions.

Advise the user, that to ensure the continued efficient and safe operation of the boiler it is recommended that it is checked and serviced at regular intervals.The frequency of servicing will depend upon the particular installation conditions and usage, but in general once a year should be enough.

Draw attention, if applicable, to the current issue of the Gas Safety (Installation and Use) Regulations, Section 35, which imposes a duty of care on all persons who let out any property containing a gas appliance.

It is the Law that servicing is a carried out by a competent person.

Reminder - Leave these instructions and the “Benchmark” logbook with the user.
