Make the water connections

Combi V3 and Combi Max water connections
Note: Water connections may be from the rear, left or
right hand side. If using low level side exit flue, the flue
must be on the opposite side to the water connections.
1 If required, for easier access, the case bracing bracket
may be temporarily removed. Remove the four screws
securing the bracing bracket and lift it out.
2 Removable plates are provided on both side panels
for pipe entry.
3 Fit the four push-fit elbow connectors onto the
open pipe ends. See Fig. 22. Connect the pipework
(not supplied with the boiler) to the elbows.
4 Balanced flue models - proceed with the flue installation
as described in the separate fitting instructions.
5 Conventional flue models - proceed with the flue
connection as described in Section 6.6.
6 The safety valve discharge pipe must be routed
clear of the boiler to outside, to discharge in such a
manner that it can be seen but cannot cause injury
or damage to persons or property.
7 Do not turn on the mains water supply at this stage.

Vortex Combi water connections

Flow and return pipework can be routed to either side of
the boiler, dependant on the flue system used, from the
push-fit elbows (supplied) on the flow and return
connection. Refer to Section 5.11 - Water connections.

Holes are provided in the rear of the casing side panels to
allow the condensate pipe to be run through the back of the
boiler. It will be necessary to remove the back panel from the
boiler casing to fit this pipework, and to refit the panel before
placing the boiler in its final position.
If access will be restricted, make any connections to
the boiler before placing it in its final position.
If using a balanced flue system - Install the balanced
flue system before connecting the heating system
pipework to the boiler.
