10.6 BURNER CONTROL AND ADJUSTMENT
10.6.1 Fan Speeds
The fan speeds for the Spetisbury range of burner
are pre-set and should not require adjustment.
Although max/min speeds can be adjusted if
required, adjustment of the ignition speed is not
recommended as this may affect the reliability of
operation.
10.6.2 Starting Up
AS WITH ALL FORCED DRAUGHT BURNER
SYSTEMS THE SPETISBURY SP PREMIX
BURNER MUST BE SET UP CORRECTLY TO
ENSURE SATISFACTORY AND RELIABLE
OPERATION
Note: The air pressure switch on this burner is
factory set and should not require adjustment.
Before attempting to light the burner for the first
time, suitably competent personnel should inspect
the installation to ensure the following;
a)
That all electrical safety circuits are made and
the electrical installation has been carried out
according to the instructions in this manual.
b) There must be an adequate ground to the
burner and the Live and Neutral should be
correctly connected.
c) The gas pipe work is of a suitable size for the
burner requirements and the installation has
been checked for leaks and fully purged.
On turning on the burner the display should be as
show in Fig 10.22 below.
Press the start button and after a few seconds the
burner should start to pre-purge. Ignition will
commence and the fan will stay at ignition speed for
10 seconds. The burner is pre-programmed with a
step-control, so it will not reach maximum fan speed
for approximately 90 seconds.
Once the burner has reached maximum fan speed
check the CO
2
levels. These should be the same as
shown in the table below:
Fig 10.22 Burner Display Panel
Drive the fan speed manually to the minimum
setting. This is done by pressing and holding down
for 3 seconds the hidden button below the ‘STATUS’
figure at the same time as the ‘-’ (minus) button. See
Fig. 10.22 below. The ‘STATUS’ figure will now
show;
