Using the Burner

Stand-by Mode
In Stand-by mode igniter is off, gas valve is closed, and fan is off if fan overrun time is finished and
Continuous Fan speed option is switched off.
6.2.2
Burner operation
Turn ‘On’ the main electrical supply and turn on the burner demand interlock/switch
.
The burner fan
will start and pre-purge. The burner Control will then drive the fan to a pre-set ignition speed. The
ignition spark is generated at this point and the Burner will ignite.
If satisfactory ignition takes place, the burner will remain alight and the fan speed will modulate in
response to the modulation signal input.
If however satisfactory ignition does not take place, the burner will go through
‘Post-purge’
and
‘
Pre-
purge’
before re-attempting
‘Ignition’
.
This re-cycling will take place three times (depending on the settings) before the burner will enter a
Lock-Out condition which will require manual reset by the user by depressing the
Reset
button to
restart the burner ignition sequence.
