Product specifications

The white condensate trap must be connected to the condensate outlet on the boiler. A 1” grey plastic flexible
pipe is supplied with the white trap and must be connected to the outlet on the trap. The flexible pipe can be
inserted into the open end of a vertical piece of waste pipe.
Finally
Tighten all joints, check over, fill system with water, and test for water tightness. Test for gas tightness.
NOTE!
hot water secondary circulation
If a hot water re-circulation loop is used, the instructions given in paragraph 7.10 apply, except for one
amendment.
Because the UV3 manifold is now connected directly to the boiler it is not possible to connect the return pipe of
the hot water secondary circulation to a point between the UV3 and the boiler. Instead the hot water return pipe
must now be teed into the pipe connection between the UV3 manifold and the hot water expansion valve.
