1.1 Installation
Where no British Standards exists, materials and equipment
should be fit for their purpose and of suitable quality and
workmanship.
When installing the appliance, care should be taken to avoid any
possibility of personal injury when handling sheet metal parts.
The installation of this boiler must be carried out by a competent
person in accordance the rules in force in the countries of
destination.
Manufacturer’s instructions must not be taken as overriding
statutory requirements.
1.2 Gas Supply
This boiler is for use only on G20 natural gas.
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.
1.3 Data Label
The data label is on the base panel inside the appliance.
1.4 Electrical Supply
The boiler must be earthed.
All system components shall be of an approved type and all
wiring to current I.E.E. wiring regulations.
The boiler must be connected to a permanent 230V ac, 50Hz
supply.
Connection of the whole electrical system of the boiler, including
any heating controls, to the electrical supply must be through
one common isolator.
Isolation should be by a double pole switched fused spur box,
with a minimum gap of 3mm for both poles. The fused spur box
should be readily accessible and preferably adjacent to the
appliance. It should be identified as to its use.

Condensate should, if possible, be discharged into the internal
household draining system. If this is not practical, discharge can
be made externally into the household drainage system or a
purpose designed soak away, see section 9.4 for more details.
1.6 Boiler Efficiency
The Seasonal Efficiency Domestic Boilers UK (SEDBUK) is:
Energysaver Combi 2-80: 90.6%
Energysaver Combi 2-100: 90.1%
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 has been certified by Gastec.
