INSTALLATION

COMMISSIONING

IMPORTANT DO’S AND DONT’S

DO -   

Check the incoming mains water pressure. If it exceeds 5.0 bar at any point 

in the 24 hour cycle then a pressure limiting valve set at 3.0 bar should be  

fitted where the cold supply enters the property.

DO -  

Check the flow rate of the incoming cold water main is adequate to meet 

the maximum hot and cold water simultaneous demands.

DO -    

Check that all connections are in accordance with the schematics on pages 

6 and 7.

DO -   

Fill the tank manually or adjust the ballvalve so that the water in the F & E 

tank is set to the correct level.

  

DO -   

Restrict the ballvalve fill rate when full so that the overflow pipe can cope 

with the fill rate in the event of a ballvalve failure.

DO -   

Make sure there is adequate clearance above the F & E tank to service the 

valve.

DO -   

Ensure that range-rated appliances are set to the specified design heat 

input and the boiler thermostat is set to maximum for all boilers.

DO -   

Ensure that the water level in the expansion tank is at least 250mm above the 

highest point on the radiator circuit and satisfies the boiler head required.

DO -  

Insulate any exposed pipework in the Torrent cupboard.

DO -   

Plumb the overflow warning pipe in 20mm minimum internal diameter 

tubing to discharge in a conspicuous external position, using high 

temperature uPVC or copper.

DO -  

Leave the electricity switched on to the appliance once it has been filled 

and commissioned to prevent the pump sticking.

DON’T -   Use a combined feed and vent on Torrent indirect installations.

DON’T -   Use tube smaller than 28mm between boiler and Torrent when the boiler 

exceeds 60,000 Btu (17kW) output.

DON’T -   Use dipped flow and return pipes between boiler and Torrent unless the 

boiler is fitted with an overheat switch, then follow the recommendations 

on pages 13/15/16.

DON’T -   place any clothing or other combustible materials against or on top of this 

appliance.

Torrent Stainless OV Models (heated by electricity only)

Ensure that the thermal store is filled with water to the water level mark inside the 

feed and expansion tank and the ball valve (if fitted) is adjusted correctly. 

If a ball valve is fitted turn down the service valve once the system is finally filled to 

the point where the warning/overflow pipe will cope with the discharge arising from 

a ball valve failure.

Switch the immersion heater on and allow the store to heat up to full temperature. 

The Torrent Stainless will produce at least its actual volume as DHW above 40°C when 

its entire contents are at between 75°C and 80°C. The tolerances of immersion heater 

thermostats is quite large so care must be taken to ensure that the correct temperature 

is achieved during commissioning to ensure that the desired performance is achieved. 

This means that the control thermostat may need to be set at 73°C on some cylinders, 

due to the temperature gradient through the store. The actual set point must set up 

and checked during commissioning by the installer. The rod thermostats (XB081) used 

in these immersion heater incorporate an overheat component which will operate 

at circa 85°C.

Instruct the occupant on how to use the off-peak timer (if fitted) and the appliance.

At the time of commissioning, complete all relevant sections of the Benchmark 

Checklist located on the inside back pages of this document.

Electrician/Installer: Please note that water at the hot tap does not indicate that the 

Torrent Stainless is full. Check that there is water in the feed and expansion tank before 

switching on the immersion heaters. Dry firing the elements will cause premature 

failure which is not covered by our warranty.

Non-Electric Torrent Stainless Models

Open the incoming stop valve and fill the domestic hot water system. For open vented 

heating system, fill the whole of the primary heating system and the thermal store 

with potable water through the feed and expansion tank. For sealed heating system 

fill the thermal store with potable water through the feed and expansion tank and 

the heating system to the design pressure using the filling loop.

Check the water level in the feed and expansion tank and adjust the ball valve if 

necessary. Check the whole of the primary heating and domestic hot and cold 

distribution system, including the Torrent Stainless for leaks.

It is essential that all systems function properly for optimum performance and to 

achieve this:-

•  The primary system should be commissioned in accordance with good practice 

and generally in accordance with the requirements of BS 6798, BS EN 12831, the 

CIBSE guide and BS 7593. Full details of the requirements are given in PAS 33:1999 

under section 10 Commissioning.

•  The boiler manufacturers instructions should be followed during the commissioning 

phase.

•  If a solar thermal system is fitted it should be commissioned as per manufacturers 

instructions to ensure compliance with Building regulations.

•  When using either cleansing or corrosion inhibitor chemical, the manufacturers 

instructions must be followed.

When determining the quantities of cleanser required, the volume of the Torrent 

Stainless should be added to the water content of the primary system. Although the 

Torrent Stainless has no special water treatment requirements, the radiators and other 

parts of the circuit will require the application 

of a scale and corrosion inhibitor.

If it is proposed to ‘powerflush’ the heating 

system we would recommend that the Torrent 

Stainless is isolated from the heating system 

being cleaned, as debris from the system could 

be washed into the Torrent Stainless and could 

impair its performance or 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 to ensure 

that flux residues and the installation 

debris are removed from the system (check 

with manufacturer for compatability with 

stainless steel).

•  Ensure that the store thermostat is set 

correctly and the boiler thermostat is set at 

its maximum.

•  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  (check with manufacturer for 

compatability with stainless steel).

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: -

•  Check that the space heating system 

controls (e.g. programmer, room thermostat) 

are functioning correctly.

Switch off space heating system and ensure 

that the store thermostat is set correctly and the 

boiler thermostat is set to maximum.

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.
