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.
1.4 Technical Data
All dimensions are given in millimetres (except as noted).
See diagrams 1.1 and 1.2.
The data label is positioned on the base of the boiler.

1.5 Condensate 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.
1.6 Vertical Plumbing Kits
Should any combination of the domestic hot water, heating flow
or return pipes come from above the boiler, an Upward Piping
Kit is available to facilitate, part No. A2041500.
Contact Glow-worm for further details.
