Grant Vortex Indoor/Utility, System and Boiler House Oil Boilers
Fig. 21 - Boiler flue connector
Refer to Section 4.11 and 4.12 and Fig. 12. for the size,
type and position of the connections.
The Flow and Return pipework can be routed to either
side of the boiler, dependant on the type and direction
of the flue system used.
For condensate disposal pipework refer to Section 5.
Pipe entry/exit holes in case (Indoor/Utility, System)
All models except the 155/200 and 200/240 have holes
to enable the pipework to exit the boiler casing. On the
50/70 and 50/90 models these holes are pre-cut knock-
outs located at the rear of both side panels and on the
90/120 and 120/155 models these pre-cut holes are in
the removable flue outlet cover plates.
Push out the 'knock-out' from the required holes,
taking care not to distort the side panel.
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. Once the flue system is fitted then complete the
water connections and fill the heating system.
If using a conventional flue system - Complete the
water connections and fill the heating system.
Check all connections for leaks and rectify as necessary.
1. Lift off upper rear casing panel.
2. Remove the insulation from the underside of the
panel (do not discard it). Carefully press out the
pre-cut flue opening in the top panel.
3. The flue dress panel supplied in the literature pack.
Place the dress panel in position on the rear casing
top panel and secure in place.
4. Re-fit the insulation to the panel with the foil
surface facing outwards. With a sharp knife cut

neoprene gasket and that end of studding passes
through the hole in the of the spacer bracket. Fit
washer and wing nut provided onto end of threaded
studding and secure connector in position by
tightening down on wing nut – as shown in Fig. 21.
8. Re-fit the rear top casing panel to the boiler –
fitting it over the boiler connector.
