The boiler will provide domestic hot water and central
heating and is fully automatic once switched on. Kitchen
models have a 'mains on' neon, see Fig. A, which lights
when the boiler is switched on, but does not necessarily
indicate the burner is firing.
If your model has a programmer fitted, it will provide
hot water and central heating during the periods set on
the programmer.
Kitchen and Kitchen System: To access the controls,
open the front door from the right (may be altered to
open from the left if required).
Utility and Utility System: Pull off the front access
