HOW TO START YOUR
BOILER
TO START YOUR BOILER (See Fig. 2).
(a) Switch on the electrical mains supply to the boiler.
(b) Ensure that any external controls connected to the boiler, such
as a room thermostat, are on a high setting.
(c) Set the user operating switch to heating and hot water or, if a
programmer is fitted, set it to the correct time of day and
position the selectors to ON. The power on lamp in the
control facia will light up
(d) Turn the thermostat control knob to the desired position (see
section Temperature Control).
(e) Your boiler will now commence a start sequence, in which a
pre-ignition period of approximately 15 seconds is followed by
a supply of atomised oil being introduced into the combustion
chamber. Ignition then occurs, followed by a post-ignition
period of approximately 20 seconds.
(f) Your boiler is now in a steady run condition and will remain
so until the water temperature reaches the temperature set on
the control thermostat. At this point the burner will stop and
the boiler will shut down. The sequence will continue until
the boiler is programmed – either manually or by an automatic
programmer – for a period of shutdown.
