Parts - gledhill TORRENT DIRECT Design, Installation & Servicing Instructions

When using either cleansing or corrosion inhibitor chemical, the manufactures
instructions must be followed.
(d) When determining the quantities for cleanser required, the volume of the Torrent should
be added to the water content of the primary system. Although the Torrent has no special
water treatment requirements, the radiators and other parts of the circuit will require the
application of a scale and corrosion inhibitor.
(e) If it is proposed to 'powerflush' the heating system we would recommend that the Torrent
is isolated from the heating system being cleaned. Failure to do so could seriously
damage the unit. If in doubt please contact our Technical Helpline on 01253 474584.
Fill the system and flush cold and then refill and vent the system.
Add cleanser such as Fernox Superfloc or sentinel X300 to ensure that flux residues
and the installation debris are removed from the system.
Ensure that the store thermostat is set at 75
maximum. Set the boiler/system pump to give temperature difference across the boiler
between 8 – 15
Switch on the system and to ensure full cleansing, circulation to all parts of the system
should continue for a minimum of 1 hour.
Flush the system hot having checked that there is no overflow or leaks when the
system is up to temperature.
Refill and vent the system and add appropriate amount of scale inhibitor, such as
Fernox MB1 or Sentinel X100.
(f) Set the boiler temperature to maximum and with the central heating off, let the system (i.e.
store) heat up ( Approximately 1 – 2 hours). When the store is up to temperature (75 -
o
77 C): -
open the nearest hot tap and check that the mixing valve at the Torrent unit is
delivering the desired temperature of 55±5
necessary to suit individual requirements.
Check that the space heating system controls (e.g. programmer, room thermostat) are
functioning correctly.
(g) Switch off space heating system and ensure that the store thermostat is set to 70
the boiler thermostat is set to maximum.
(h) Re-fire the boiler by running a little water and wait for the boiler to switch off. Check that
there is no live supply from the store thermostat i.e. it is satisfied.
