5.4.3 Making the Water Connections (Fig. 22)
1. There are two water connections at the top of the boiler. The left
connection is the return pipe (indicated with blue label) and the flow
the right hand one (indicated with red label). Remove the sealing
caps from the boiler connections.
2. It is essential that the flow and return pipes are connected to the
boiler correctly. The boiler connections will accept 22mm
compression fittings. Capillary solder fittings MUST NOT be used.
For a top flue installation make sure the water connections do not
clash with the flue position.
When soldering of joints is to be performed under
the boiler the condensate trap must be removed
to prevent damage.
5.4.4 Filling the Condensate Trap (Fig. 23)
1. The condensate trap must be filled with water before the boiler is
commissioned.
2. Undo the securing screws and remove the facia panel with the
User Interaction Controller.
3. Disengage the condensate trap securing clip by pulling forwards
and hinging upwards (Fig. 23a). Carefully pull out the trap and
remove and discard the sealing cap.
4. The condensate trap must be primed by filling with tap water to a
depth of approximately 75mm.
5. Carefully relocate the condensate trap in the boiler ensuring all
seals are located properly and re-engage the securing clip (Fig.
23b).
6. If necessary remove the boiler front panel to inspect that the
seals are located properly and refit the facia panel with the User
Interaction Controller.
5.4.5 Connecting the Condensate Drain (Fig. 23)
1. Using the 90° rubber hose supplied, connect the condensate
drain pipework to the boiler condensate trap outlet pipe.
Ensure the discharge of condensate complies with any
national or local regulations in force (see British Gas "Guidance
Notes for the Installation of Domestic Gas Condensing Boilers" &
HHIC recommendations) and Section 5.3.5. The pipework should
be supported at least every 0.5M and where a change of direction
occurs, e.g. an elbow
2. The hose will accept 21.5mm (3/4in) plastic overflow pipe which
should generally discharge internally into the household drainage
system. If this is not possible, discharge into an outside drain is
acceptable.
5.4.6 Connecting the gas Supply (Fig. 23c)
1. The elbow and nut assembly supplied must be used to connect
to the gas supply. The flared end of the elbow is 22mm O.D.
2. Engage the nut onto the gas cock, ensuring that the sealing
washer is in place. Tighten the nut.
