Safety Valve Discharge
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
27).
The system should be carefully checked for leaks, as frequent
refi lling 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 fl ow. Please only use drain
pipe material compatible with condensate products (refer to BS
6798:2009).
The condensate fl ow can reach 2 litres/hour because of the
acidity of the condensate products (Ph close to 2), take care
before operation.
See page 13 for condensate discharge options.
