Safety Valve Discharge and Condense Outlet
The pressure relief valve pipe is made of copper. It
should terminate below the boiler safely outside
the premises. Care should be taken that it does
not terminate over an entrance or window or
where a discharge of heated water could endanger
occupants or passers by.
Warning !
Do not apply heat to the copper safety valve
outlet pipe whilst it is connected to the 3 bar
safety relief valve.
Fill the central heating and DHW system and
bleed air from the system as described in the
Commissioning instructions (page 8).
The system should be carefully checked for
leaks, as frequent refilling could cause premature
system corrosion or unnecessary scaling of the
heat exchanger. The pipe from the trap should be
connected to a drain as described in the relevant
regulations.
Pay special attention not to bend the condensate
silicone drain pipe is such a way as to interrupt the
flow. Please only use drain pipe material compatible
with condensate products (refer to BS 6798:000).
The condensate flow can reach  litres/hour because
of the acidity of the condensate products (Ph close
to ), take care before operation.
See page 13 for condensate discharge options.
