4.6.5 SAFETY VALVE (fig. 14)

Connect a discharge pipe to the fixing jig connection and tighten.

The discharge pipe must have a continuous fall away from the

appliance to outside and allow any water to drain away thereby

eliminating the possibility of freezing. The discharge pipe must

terminate in a position where any water – possibly boiling –

discharges safely without causing damage or injury, but is still

visible.

4.6.6 CONDENSE PIPE

During normal operation the boiler produces condense which is

collected in a trap located in the lower part of the boiler. A flexible

pipe (condense outlet pipe) is connected to the outlet of the trap.

The flexible pipe must be connected to a plastic waste pipe only.

The plastic waste pipe must have a minimum of a 3º fall towards

the drain. Any external run of pipe should be insulated to prevent

the risk of freezing.

CONNECTING THE CONDENSATE OUTLET

Gently pull the condense outlet pipe down from its location inside

the boiler until it protrudes from the underside of the boiler. Connect

a suitable plastic (not copper) pipe (no less than 20mm diameter)

to the outlet pipe and ensure it discharges in accordance with

building regulations or other rules in force (see fig. 15A for examples).

4.6.7 CONNECTING THE CONDENSATE OUTLET

Gently pull the condense outlet pipe down from its location inside

the boiler until approximately 100mm protrudes from the underside

of the boiler. Connect a suitable plastic (not copper) pipe (no less

than 20mm diameter) to the outlet pipe and ensure it discharges in

accordance with building regulations or other rules in force.

4.7 ELECTRICAL CONNECTIONS

The electrical supply must be as specified in section 3/3A. A

qualified electrician should connect the electrical supply to the

appliance. If controls – external to the appliance – are required, a

competent person must undertake the design of any external

electrical circuits, please refer to section 8 for detailed instructions.

ANY EXTERNAL CONTROL OR WIRING MUST BE SERVED

FROM THE SAME ISOLATOR AS THAT OF THE APPLIANCE.

The supply cable from the isolator to the appliance must be 3-core

flexible sized 0.75mm to BS 6500 or equivalent. Wiring to the appli-

ance must be rated for operation in contact with surfaces up to 90 °C.

4.7.1 CASING REMOVAL (fig. 15)

Remove transit screws C once the boiler has been mounted on the

wall.

To gain internal access to the appliance you must first remove the

casing, proceed as outlined below:

- locate and remove the screw A;

- remove the cover from the underside of the appliance casing;

- locate and remove the 2 screws B located at the Left & Right of the

underside of the casing;

- lift the casing upward to disengage it from the top locating hooks

and then remove;

- store the casing and screws safely until required. Re-fit in the

reverse order.

4.7.2 APPLIANCE TERMINAL BLOCK

The appliance terminal block is located on the rear of the control

fascia. Remove the casing as described in 4.7.1. Lift the control

fascia upward and lower it. Locate the terminal block covers (see

fig. 16).

NOTE

The appliance comes with a factory fitted link to allow basic operation

of the boiler via the mode selector switch. If it is anticipated that external

controls will be required please refer to the wiring diagrams in section

8 for more detailed information.

4.7.3 CONNECTING THE MAINS (230V) INPUT (see fig. 17)

Locate and remove the screw securing the right terminal block

cover (230V). Pass the cable through the cable anchorage point.

Connect the supply cable wires (LIVE, and NEUTRAL) to their

corresponding terminals on the appliance terminal block. Connect

the EARTH wire to the EARTH block (see fig. 17) ensuring that it’s

left slightly longer that the others, this will prevent strain on the

EARTH wire should the cable become taut.

Do not remove the link wire unless additional external controls are

to be fitted (see section 8). The securing screw on the cable

anchorage should now be tightened. This must be done before the

control fascia is re-fitted in the upright position. The appliance

casing, screws, and lower cover can now be re-fitted.
