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.
3. 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

1. The condensate trap must be filled with water before the
boiler is commissioned.
2. If access to the condensate trap is impeded remove the facia
panel with the User Interaction Controller.
3. Disengage the condensate trap retaining clip and carefully
pull out the trap. Remove and discard the sealing cap.
4. Fill the condensate trap 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 reattach the retaining clip.
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.
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. 23a)
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.
