Ensure that the thermal store cistern is filled with water to the water level mark inside
the feed cistern and the ballvalve (if fitted) is set correctly.
Switch the immersions on and allow the store to heat up to its full temperature
(around 77°C).
When the store has been fully charged open the nearest hot tap and check the
mixing valve at the Torrent unit is delivering the desired temperature. (Note:- the
mixing valve is factory set around 55°C ±5°). Adjust if necessary to suit individual
requirements.

PLEASE NOTE WATER AT THE HOT TAP DOES NOT INDICATE THAT THE CYLINDER
IS FULL.
CHECK THAT THERE IS WATER IN THE FEED AND EXPANSION TANK BEFORE
SWITCHINg ELECTRICITY ON TO THE ImmERSION HEATERS. “DRY FIRINg” THE

• Ensure that the thermal store cistern is filled with water to the water level mark
inside the feed cistern and the ballvalve (if fitted) is set correctly.
• Ensure that the store thermostat is set at 70°C. Check the
boiler control
thermostat is set at maximum
.
When the boiler switches off check that
the store thermostat is not calling for heat and is satisfied. The boiler
may cycle two or three times to achieve this.
• When the store has been fully charged open the nearest hot tap and check
the mixing valve at the Torrent unit is delivering the desired temperature.
(Note:- the mixing valve is factory set around 55°C ±5°). Adjust if necessary to
suit individual requirements.
It is essential that the system functions properly for optimium performance.
To achieve this, the system should be commissioned in accordance with good
practice and generally in accordance with the requirements of BS 6798, BS
5449 and BS 7593: 199.
• Fill the system and flush cold.
• Refill the system.
• Add a cleanser such as Fernox Superfloc or Sentinel X300 to ensure that
flux residues and installation debris are removed from the system.
When
determining the quantity of cleanser required, on open vented systems,
be sure to allow for the increased volume of water in the primary circuit
due to the thermal store.
• Commission the boiler.
• If the boiler is range rated, then adjust to the specified design heat input.
• Set the pump between boiler and Torrent to a temperature difference across
the boiler between 8 - 11
o
C.
• 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 when the system
is up to temperature.
• Refill the system.
Although the standard Torrent has no special
water treatment requirements, the radiators
and other parts of the circuit will benefit
from the application of a corrosion and scale
inhibitor, such as Fernox MBI or Sentinel X100.
When determining the quantity of inhibitor
required, on open vented systems, be sure
to allow for the increased volume of water
in the primary circuit due to the thermal
store.
Set the boiler to maximum.
With the central heating system off, let
the system heat up (1.5 hours - hours
approximately).
• Check that the space heating system
controls are functioning correctly i.e.
CLOCK AND ROOm THERmOSTAT.
• Switch off space heating system.
• Ensure that the store thermostat is set to
70°C.
• Ensure that the boiler thermostat is set to
maximum.
• Establish that the temperature difference
between the flow and return at the boiler
is not more than 11°C.
If it is more than 11°C, and the pipes
are sized correctly, then check that
in accordance with good practice, air
air vents have been fited at high points.
Increase the pump setting if necessary.
Check for obstructions in the pipework.
Final Setting of Store Thermostat
Ensure that the heating clock is set to “off”.
Refire the boiler by running a little water, wait
for the boiler to switch off. Check that there is
no live supply from the store thermostat and
the stat has been satisfied.
