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.

FITTING THE FLUE ASSEMBLY
6.1
With Sufficient Clearance To Insert Assembly From Inside
6.1.1 Insert the flue assembly into the wall.
6.1.2 Insert the flue bend in the top plate of the boiler
6.1.3 Secure the flue bend.
6.1.4 Fully insert the flue assembly into the boiler flue bend. Insert the self tapping screw supplied. Fully tighten.
6.1.5 Check the terminal relationship with the wall as shown in fig. 12.
6.1.6 Make good internal wall face.
6.1.7 Make good the outside wall face, re-weatherproof.
6.2
With insufficient Clearance To Insert Assembly From Inside
6.2.1 Insert the flue bend in the top plate of the boiler
6.2.2 Secure the flue bend.
6.2.3 From outside, push flue duct, then the air duct through the wall.
6.2.4 Fully insert the flue duct into the flue bend, then the air duct. Secure the air duct with the self tapping screw provided.
6.2.5 Continue as detailed in 6.1.5 above.

ELECTRICAL INSTALLATION
Electrical installation must be carried out by a competent electrician. The appliance is to be connected to a 240 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 240 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 240 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.
