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 labelling on the
thermal store.
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 -
Check the pump setting. This should be set as high as possible (consistent
with not creating noise) so as to give a small temperature difference across
the boiler, i.e. not greater than 11°C.
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 page 15.
DON'T - place any clothing or other combustible materials against or on top of this
appliance.
