10. If a flue extension is to be used, secure and seal this to
the bottom half of the Vertex Flue as follows:-
Locate the flared end of the extension over the open
end of the Vertex Flue. Ensure that the inner flue tubes
are engaged.
Rotate the tube until the three fixing holes line up, then
secure the tubes together using the three screws
supplied with the flue extension. Seal the joint with the
tape supplied with the flue extension.
If another one or two extensions are to be fitted, you will
have to drill through the pilot holes, in the flared end of
the extension after the extension has been fitted - use a
2.8 mm diameter drill, taking care not to damage the
inner flue tube with the drill. Secure the extension using
the three screws supplied with the flue extension. Seal
the joint with the tape supplied with the flue extension.
11. Pass the Vertex Flue assembly (mesh first) up through
the hole into the roof space. Secure the sealing plate in
position with four 1 in long No.8 woodscrews, not
supplied. Temporarily support the flue.
12. Remove the sealing ring and clamping plate from the
rear of the chassis, remove the sealing plate and four
fixing screws from the top of the chassis and fit this to
the rear of the chassis.
13. Lift the boiler into position over the wall plate. The two V
shaped cut outs in the top mounting bracket locate
behind the two prongs on the wall plate. Take care not
to damage the flue.
14. Insert a woodscrew (not supplied) into the bottom fixing
hole to secure the boiler to the wall.
15. Remove the four screws securing the fan to the flue
diverter, rotate the fan so that the outlet is facing
upwards and secure it to the diverter with the four
screws previously removed. Remove the 3 screws
securing the fan motor to the fan assembly. Rotate the
motor so that the motor support is again positioned at
the underside of the fan.
16. Replace the fan assembly on top of the flue hood.
Reconnect the fan motor leads (polarity not important)
and air pressure switch tube.
17. With the fan assembly resting on the fluehood push it to towards the rear of the boiler locating the base under the
returns at the rear of the flue hood. Secure the front of the fan assembly to the flue hood with the two screws
previously removed.
18. Position the gasket and vertical flue adaptor in position on top of the chassis and secure in place with four M4 x 16 mm
long hex. head screws - all supplied with the kit.
19. Pass the flue tube sleeve down through the adaptor and over the fan outlet and push fully home.
20. Lower the flue system down into the adaptor, ensuring that the inner tube of the flue locates over the flue tube sleeve
on the fan outlet. Secure the flue to the adaptor using the three No.8 x 10 mm long screws, supplied with the kit, into
the three pilot holes previously drilled.
