Connection I is RC½ (½ in BSPT internal).
Connection J is a blanked copper pipe.

A  -    Safety open vent
B   -   Cold feed/expansion 
C  -  Primary fl ow (from boiler)
D  -  Primary return (to boiler)
E   -   Central heating return
F   -  Central heating fl ow
G   -   Domestic hot water
H  -  Incoming mains cold water
I  -   Drain (valve is not provided with the
        appliance)
J    -   Primary fl ow for pumped summer  
 

  towel rail circuit (see page 16)

Note:  The safety open vent and cold feed/
expansion must be connected to the F & E 
cistern using the pipework assembly provided. 
Do not alter or connect any pressure-relief 
device to the vent pipe of this water heater.

All factory made joints should be checked  
after installation in case they have been 
loosened during transit.

The fi ttings for the feed and expansion cistern 
should be installed following the instructions 
provided in a position to suit the particular
