Introduction
The
istor HE260 & HE325
are fully automatically controlled,
condensing, system store, fan flued boilers.
Due to the high efficiency of the boiler, condensate is produced
from the flue gases and this is drained to a suitable disposal
point through the plastic waste pipe at the lower rear of the
boiler. A condensate 'plume' will also be visible at the flue
terminal.
The
istor
is a system store boiler providing both central heating
and domestic hot water.

In your own interest, and that of safety, it is the law that this boiler
must be installed by a CORGI registered installer, in accordance
with the above regulations.
It is essential that the instructions in this booklet are
strictly followed, for safe and economical operation of
the boiler.
Electricity Supply (boiler)
This appliance must be earthed.
Supply: 230 V ~ 50 Hz. The fusing should be 3A.
Connection must be made in a way that allows complete
isolation of the electrical supply such as a double-pole switch,
having a 3mm (1/8") contact separation in both poles, serving
only the boiler and system controls. Alternatively, a 3-pin
UNSWITCHED socket may be used. The means of isolation
must be accessible to the user after installation.
Electricity Supply
(immersion heater)
Supply: 230 V ~ 50 Hz. The fusing should be 13A.
The immersion heater is supplied fitted to the cylinder and is
