8. RUNNING YOUR SYSTEM
Page 8
TM
Run the system at fully open, maximum temperature for 1 hour, to expel any air in the system. Release any air that may be trapped at appropriate
radiator bleed points and return manifold bleed point. Turn off TRV/flow manifold and allow to cool. Set to desired room setting and run
normally.
NOTE
: DiscreteHeat recommend flushing the system with ThermaSkirt Cleanser TS3 or alternatively Scalemaster SM3 (check dosage
carefully) and running with ThermaSkirt corrosion inhibitor TS5 or alternatively Scalemaster SM5 or SM10 (check dosage carefully) to
ensure maximum longevity and reliability. Hard water areas may require additional precautions. Chemically softened water must NOT be used. This is
a standard precaution for ALL wet heating systems and a requirement of BS 7593:2006. Contact DiscreteHeat for specific application advice.
Failure to provide a suitable corrosion inhibitor will invalidate your warranty!
PROBLEM
CAUSE
SOLUTION
Leak at joint.
Faulty / incorrect installation.
Drain and replace fitting or ‘O” ring from spares kit.
Leak on ThemeSkirt pipes.
No inhibitor fitted.
Drain down, cleanse with TS3 and install inhibitor TS5.
Corrosion chemical/cleaner left in system
Drain down, replace piece, cleanse with TS3 and refill.
ThermaSkirt not hot.
Check boiler.
Is heating ’ON’ and pressure OK?
Lockshield valve closed.
Open Lockshield valve ( ).
TRV valve closed / off.

Water from return manifold
Manifold not closed fully.
Turn to ‘OFF’ position.
Noise - ticks & clicks when heat on

On installation, in a convenient place at the highest point
of the system, ‘T’ off into a vertical leg 600mm high and
install an automatic/manual air vent.
Following the procedure above, close and open each

system in turn.
Any air forced round the system will be expelled through
the boiler or through the air vent.
Air can also be bled from the bleed screw on top of the

10. BLEEDING YOUR SYSTEM
may get trapped in the existing pipework to and from the skirting. Follow these simple steps if you discover cold sections of the ThermaSkirt
which do not heat up.
Turn off all radiators and ThermaSkirt thermostatic and lockshield
valves. Make sure your system is fully pressurised and the pump is
set to max. Run the system for a few minutes, and, starting from
the lowest
point
in
the
house,
open
each
radiator/ThermaSkirt system, one at a time. Run for a further 2
minutes (approx) , close again and move to the next Ther-
maSkirt or radiator, moving upwards in the house. Any air will
be expelled through the boiler or trapped in a conventional
radiator. Bleed the radiator as normal.
