Optima Company 1001 With Sufficient Clearance To Insert Assembly From Inside, Procedure

1001

6.0FITTING THE FLUE ASSEMBLY

6.1With Sufficient Clearance To Insert Assembly From Inside

6.1.1Insert the flue assembly into the wall.

6.1.2Insert the flue bend in the top plate of the boiler

6.1.3Secure the flue bend.

6.1.4Fully insert the flue assembly into the boiler flue bend. Insert the self tapping screw supplied. Fully tighten.

6.1.5Check the terminal relationship with the wall as shown in fig. 12.

6.1.6Make good internal wall face.

6.1.7Make good the outside wall face, re-weatherproof.

6.2With insufficient Clearance To Insert Assembly From Inside

6.2.1Insert the flue bend in the top plate of the boiler

6.2.2Secure the flue bend.

6.2.3From outside, push flue duct, then the air duct through the wall.

6.2.4Fully insert the flue duct into the flue bend, then the air duct. Secure the air duct with the self tapping screw provided.

6.2.5Continue as detailed in 6.1.5 above.

7.0ELECTRICAL 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).

7.1Procedure

7.1.1The supply cable must be no less than 0.75 mm (24x0.2 mm) to BS6500 table 16.

7.1.2The 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.

7.1.3Secure 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.

7.2Room Thermostat (fig. 18) (or remote time clock connection)

7.2.1Please 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).

7.2.2If 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.

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.
