6.0 FITTING THE FLUE ASSEMBLY
6.1 With Sufficient Clearance To Insert Assembly From Inside
6.1.1 Push the air duct seal onto the air duct at the cut end.
6.1.2 Insert the flue assembly into the wall ensuring a 2° slope back to the boiler.
6.1.3 Make good internal wall face.
6.1.4 Fully insert the flue assembly into the turret spigot. Insert the self tapping screw supplied. Fully tighten.
6.1.5 Secure the turret.
6.1.6 Slide the air duct seal over the joint.
6.1.7 Check the terminal relationship with the wall as shown in fig. 12.
6.1.8 Make good the outside wall face, re-weatherproof.
6.2 With insufficient Clearance To Insert Assembly From Inside
6.2.1 From outside, push flue duct, then the air duct through the wall.
6.2.2 Push the air duct seal over the air duct.
6.2.3 Fully insert the flue duct into the turret, then the air duct. Slide, back the seal and secure the air duct with the self
tapping screw provided.
6.2.4 Slide the seal over the joint and secure the turret.
6.2.5 Continue as detailed in 6.1.8 above.
7.0 ELECTRICAL INSTALLATION
Electrical installation must be carried out by a competent electrician. The appliance is to be connected to a 230 V ~ 50
Hz supply (see fig. 18). The supply fuse rating is 3A. The terminals are accessible after removing the white base plate
and single screw securing the terminal cover (see fig. 18).
7.1 Procedure
7.1.1 The supply cable must be no less than 0.75 mm (24x0.2 mm) to BS6500 table 16.
7.1.2 The earth conductor must be cut longer than the live and neutral (fig. 19).
Connect the Supply Cable to the terminal block marked 230 V ~ 50 Hz, L, N, the supply cable is to be connected as follows:
i) Connect the brown wire to the L (live) terminal).
ii) The blue wire to the N (neutral) terminal.
iii) The green/yellow wire to the (earth) terminal.
7.1.3 Secure the cable with the cable clamp. The supply cable can be connected to the mains supply by the use of an unswitched
shuttered socket-outlet in conjunction with the 3A fused 3 pin plug both in accordance with BS 1363. This provides complete
isolation. Alternatively, a fused double pole switch having a contact separation of at least 3 mm, in all poles and provided
just for the boiler and its external controls can be used. A wiring diagram is provided on the appliance, attached to the
rear of the front panel. In addition, there is one in this manual (fig. 25). Attention is drawn to the requirements of the current
I.E.E. Regulation and in Scotland, the electrical provisions of the Building regulations.
7.2 Room Thermostat (fig. 18) (or remote time clock connection)
7.2.1 Please note that the room thermostat, clock switch connection is 24 V. To connect mains voltage to these terminals will
seriously damage the printed circuit board. The room thermostat and clock switch connector block is situated within the
connector box. Twin core cable should be used for this connection (terminals 4 and 5).
7.2.2 If using a remote 230 Volt time clock ensure that the motor and switch connections are totally separate in the clock and
that the switch connections are independent for the 24 Volt terminals (4 and 5) on the boiler.
External controls: room stat or remote time
clock in the place of loop terminals 4 and 5.
Please note 24 V only, use only voltage free
contacts.
IMPORTANT
If 230 V is
connected to
terminals 4 or 5,
damage will be
caused to the
P.C.B.
