orange "burner on" indicator
21 will
light and the heating will be on.
When there is a need for hot water while
the heating is on, it is only necessary to
turn on a hot tap. The heating will be
interrupted momentarily while the hot
ater is being delivered. The boiler will
w
switch back automatically to heating
hen the tap is turned off.

Note: if the boiler has been turned off for
some time the first attempt to light it may
result in a lockout . If this happens
press the reset button
23 and the boiler
will light.
To Turn Boiler Off Completely
1) Turn the selector switch 15 to the off
position
2) Turn the gas tap

When a tap or shower is turned on, the
flow of mains water, above 2 litres per
min., will activate the 3 way valve

tem anticipates the changes of
temperature in the secondary heat
exchanger and ensures accurate temperature regulation.
When the tap is closed the burner is extinguished and the pump stops.
Priority will be given to a demand for hot
water. This will interrupt the central heating for the duration of hot water delivery.

The central heating flow temperature is
controlled by the central heating control

9 Fig. 5. The boiler has been
designed to minimise cycling and will not
attempt to relight for 3 minutes after the
boiler thermostat has been satisfied (it is
possible to reduce the time to 30 s if
necessary). When the room thermostat
is satisfied the burner will switch off and
the pump will remain running for a further 4 minutes before it stops.
NB : it is possible to override the 3 minute
delay by putting off and on the central
heating selector switch 17.
