Burner start up procedure

Turn on the oil supply, connect electrical
supply.  Ensure that the thermostat and
time clock are calling for heat.  Bleed the
air through the pump by slackening the
oil pump plug.

Note  Where a deaerator is used, release
the air through knurled nut on the top of
the deaerator.

During this purging sequence the burner
may go to lock out.

Depress lockout reset.

Once the air is purged, retighten the oil
pump plug.

If adjustment is required see Figure 11.

Check air regulator is set to 4.5.

Observe start up sequence;

• 1 Fan runs
• 2  Spark ignition is energized
• 3  Oil solenoids open
• 4 Ignition successful

If ignition fails air may still be present
within the system.  Purge the air as 
necessary.  Depress lockout reset to
restart ignition sequence.

Turn off electrical supply and attach the
oil pressure gauge to pressure gauge
port on pump firstly removing oil pump
plug.

Reconnect the electrical supply.  Check
the oil is set to 130psi (9bar) if necessary
adjust at oil pump with a suitable allen
key.

Run the burner for a minimum of 15
minutes, then check the combustion
products in the flue with a suitable gas
analyser adjust air regulator to give CO2
of 10-10.5% and a smoke No. 0.
