1. BOILER LOCATION
Always ensure the following clearances are available around the casing of the boiler:-
Top: 235 mm, Bottom: 250 mm, Each side: 5 mm, Front: 450 mm
Do not store any other articles in the cupboard containing the boiler and never place any clothing or combustible material on
or near the boiler or flue pipe.
2. FLUE TERMINAL
The terminal on the outside wall must not be allowed to be obstructed. If it is damaged, in any way, turn the boiler off and
contact your Service Engineer.
Note: The Alpha CD boilers are high efficiency condensing boilers and when operating vapour will be emitted from the
terminal. This is safe and quite normal.
3. MAINS FAILURE
In the event of an electrical supply failure the boiler will not operate. When the supply is restored, the boiler will return to
normal operation. Remember to reset the clock, if fitted, when the supply is restored.
If the mains water supply fails, there will be no hot water from the taps. The boiler will continue to provide central heating.
4. ADDITIONAL BATHROOM FITTINGS
Any equipment such as mixing valves, showers, bidets etc. must be designed to operate at mains water pressure. Contact
your plumbing merchant or installer for advice when considering purchasing such items.
5. CLEANING
Use only a damp cloth and mild detergent to clean the boiler outer casing. Do not use abrasive cleaners.
6. SERVICING
To maintain efficient and safe operation of your boiler, routine annual servicing is essential.
For advice on servicing contact:- The Alpha Helpline: 0844 8718764.
7. GAS LEAK
If a fault or gas leak is suspected, turn off the gas supply. Do not touch any electrical switches, do not smoke and extinguish
all naked flames. Contact your local Gas Region immediately.
8. ELECTRICAL SUPPLY
The boiler requires a 230/240 V ~ 50 Hz supply, fused at 3 A if a 13 A 3-pin plug is used or a 5 A fuse if any other type of
plug is used.
To connect a plug:-
The colour of the wires in the mains lead of the boiler may not correspond with the coloured markings identifying the
terminals in your plug. In this case proceed as follows:-
The wire coloured green and yellow must be connected to the terminal in the plug that is marked with the letter E, or by the
earth symbol
, or coloured green or green and yellow.
The blue wire must be connected to the terminal which is marked with either the letter N or coloured black.
The brown wire must be connected to the terminal which is marked with the letter L or coloured red.
THE APPLIANCE MUST BE EARTHED.
