5 CONDENSATE DRAINAGE
High efficiency (condensing) boilers remove more useful heat from the combustion gases, resulting in additional water
vapour which is collected within the boiler (as condensate) and run to a suitable drainage point via the condensate
drainage pipe.
Where possible the condensate drain should be connected internally to a waste pipe within the property to prevent
the risk of freezing.
If the condensate drain pipe runs outside it should be fitted with increased diameter pipe and be suitably lagged to reduce
the risk from freezing.
In situations where there are likely to be extremes of temperature or wind-chill the use of a proprietary trace-heating system
for external condensate drainage pipework, incorporating an external frost thermostat, should be considered.
6 GAS SAFETY REGULATIONS
Current Gas Safety (Installation and Use) Regulations:-
It is the law that all gas appliances are installed and serviced by a competent person, i.e. Gas Safe registered
personnel. Failure to install or service appliances correctly could lead to prosecution. It is in your interest and that
of safety to ensure compliance with the law. The manufacturer's instructions must not be taken in any way as over-
riding statutory obligations.
The Benchmark Checklist must be fully completed by the installer on installation of the boiler. The Benchmark Checklist is
shown in back of the Installation and Servicing instructions. All Gas Safe registered installers carry a Gas Safe ID card and
have a registration number. Both should be recorded in the Checklist. You can check your installer is Gas Safe registered by
calling Gas Safe on 0800 408 5500.
It is a requirement that the boiler is installed and commissioned to the manufacturers instructions and the data
fields on the commissioning checklist completed in full.
To instigate the boiler guarantee the boiler needs to be registered with the manufacturer within one month of the
installation.
To maintain the boiler guarantee it is essential that the boiler is serviced annually by a Gas Safe registered engineer who has
been trained on the boiler installed. The service details should be recorded on the Benchmark Service Interval Record and
left with the householder.
