WARNING: This appliance must be wired in accordance with
these instructions. Any fault arising from incorrect wiring cannot
be put right under the terms of the Glow-worm guarantee.
All system components must be of an approved type.
Electrical components have been tested to meet the equivalent
requirements of the BEAB.
Connection of the whole electrical system and any heating
system controls to the electrical supply must be through a
common isolator.
Isolation should preferably be by a double pole switched fused
spur box having a minimum contact separation of 3mm on each
pole. The fused spur box should be readily accessible and
preferably adjacent to the boiler. It should be identified as to its
use.
A fused three pin plug and shuttered socket outlet may be used
instead of a fused spur box provided that:
a) They are not used in a room containing a fixed bath or
shower.
b) Both the plug and socket comply with the current issue of
BS1363.
The mains electrical supply must be maintained at all times in
order to provide domestic hot water.
