Lockout
The Lockout condition is a built
in
safety device which comes into operation
when
the
burner
controls suspect
or
register
that
a fault
has
developed
that
could cause
damage
to the burner.
Several things can create this situation such as:-
Oil tank allowed to
run
out
of fuel.
The valves
in
the oil line have been turned off.
The fire check valve has operated.
Air
in
the
supply
pipe;
usually
caused
by
allowing the
tank
to
run
dry,
then
on
refilling
not
bleeding the air from the
supply
pipe.
Wrong grade of fuel supplied.
Water contamination of the oil tank, this
is
quite common where the inspection doors
or
vent caps
etc. have been left open.
Faulty
or
contaminated filter causing blockage to the
burner
nozzle.
No
ignition at the
burner
nozzle
due
to
burner
fault.
In
most cases it is recommended that a qualified service engineer is employed
to
correct the
fault.
Lockout Reset
If
the boiler goes to lockout condition, this is indicated
by
the illumination of the
RED
NEON
on
the control panel.
To
reset the
burner
the following procedure should be followed:-
1.
Remove the lower front panel.
2.
On
the
burner
control box a glowing
red
button
will
be
noticed. This is the Lockout Reset
Button.
3.
Turn the boiler thermostat to the OFF position.
4.
Press the Lockout Reset Button fully horne.
5.
Release the Lockout Reset Button. The light will go
out
and
should remain so.
6.
Turn the boiler thermostat to the required setting. The ignition .cycle should then automatically
commence.
7.
If
Lockout continues to re-occur
then
a competent engineer should be consulted. Do
not
attempt
to adjust the
burner
or
its controls.
Note:
If
the oil storage tank has been allowed
to
become
empty
then air
may
be present
in
the
supply
pipe. The oil
supply
pipe
will require either 'bleeding'
if
it is a
one
pipe system
or
the
continued resetting of the lockout to clear the air
on
a
two
pipe system.
It
is always useful to
consult
your
installer as to which system is fitted.
