, fused 3A.
The Seasonal Efficiency Domestic Boilers UK (SEDBUK)
is 87.9%.
The value is used in the UK Government’s Standard Assessment
Procedure (SAP) for energy rating of dwellings. The test data
from which it has been calculated have been certified by B.S.I.
1.5 Gas Supply
The gas installation must be in accordance with the current issue
of BS6891.
The supply from the governed meter must be of adequate size
to provide a steady inlet working pressure of 20mbar (8in wg) at
the boiler.
On completion, test the gas installation for soundness using the
pressure drop method and suitable leak detection fluid. Purge
in accordance with the above standard.
1.6 Electrical Supply
WARNING. This boiler must be earthed.
All system components shall be of the approved type and be
wired and connected in accordance with the requirements of the
current issue of BS7671 and any applicable local regulations.
Connection of the boiler and system controls to the mains supply
must be through a common isolator and must be fused 3A
maximum. This method of connection should be, by a double
pole isolating switch, which has a minimum contact separation
of 3mm on both poles. This should be readily accessible and
preferably adjacent to the appliance. It should supply the
appliance only and be easily identifiable as so doing.
Wiring to the boiler must be PVC insulated type to the current
issue of BS6500 Table 16.
Alternatively, an unswitched shuttered socket and 3 pin plug to
the current issue of BS1363, fused 3A, may be used, provided
it is not used in a room containing a bath or shower.
1.7 Condensate
The boiler condensate should, if possible, be discharged into the
household internal draining system, that is, sink or washing
machine drain. If this is not practicable, discharge can be
external, into the household drainage system or a purpose
designed soak away
The boiler is fitted with a safety device to prevent the boiler from
working if the condensate pipe gets blocked by either ice or
debris.
It is, therefore, recommended that any external condensate
drain pipe is insulated to prevent it freezing up.
Alternatively, a larger diameter pipe can be used and insulated.
The condensate drain pipe should be checked during any
servicing and any debris found removed.
Refer to the British Gas publication “Guidance Note for the
Installation of Domestic Condensing Boilers” for further
information.
1.8 Heating System Controls
The heating system should have installed: a programmer and
room thermostat controlling the boiler.
Thermostatic radiator valves may be installed in addition to the
room thermostat.
Note: For further information, see The Building Regulations
1991 - Conservation of fuel and power, 1995 edition - Appendix
G, table 4b.
1.9 Anti-theft Kits
Anti-theft kits are available for these appliances, contact Hepworth
Heating Ltd. for further information.
