Important Do’s and Don’ts
DO
-
Check the incoming mains water pressure. If it exceeds 3.5 bar at any point
in the 4 hour cycle then a pressure limiting valve set at 3.5 bar should be
fitted where the cold supply enters the property.
DO
-
Check that all connections are in accordance with the labelling on the
thermal store.
DO
-
Fill the cistern manually or adjust the ballvalve so that the water in the
F & E cistern 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 cistern 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 cistern is at least 50mm
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 0mm 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.
DON’T
- Use a combined feed and vent on Torrent indirect installations.
DON’T
- Use tube smaller than 8mm 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.
DON’T
- place any clothing or other combustible materials against or on top of this
appliance
