1 Technical Information
1.3 Gas Supply
The gas installation must be in accordance with the relevant
standards.
In GB this is BS6891.
In IE this is the current edition of I.S.813 "Domestic Gas
Installations".
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.

The Seasonal Efficiency Domestic Boilers UK (SEDBUK) is:
18 and 30 sxi: Class 'A'.
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 B.S.I..
1.5 Condensation Drain
A plastic drain pipe must be fitted to allow discharge of
condensate to a drain.
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 8.2 for more
details.

boiler a vertical plumbing kit is available,
