If any adjustments have been made, re-check both high
and low fire once more.
6. Gulliver burners are manufactured to EN 676 standard
and fitted with a singular air pressure switch.
Turn the switch at the lowest setting. With the burner
working at the required output, adjust the dial clockwise,
increasing its value until the burner shuts down. Reduce
the value by one set point, turning the dial anti-clockwise.
Check for reliable burner operation, if the burner shuts
down, reduce the value by a half set point.
7. Measure the CO2 content of the flue gases. If necessary
adjust the combustion air damper of the burner (Refer
to the Burner Instructions) to obtain a CO2 reading as
indicated in section 1.2 (±0.5)
8. Turn OFF the burner, remove pressure gauge and refit
sealing screw in pressure test point and flue sample point
cover plug.
Refer to the burner instructions supplied with the heater
.
After making final gas rate checks all joints on the gas
controls assembly must be tested for soundness using
leak detection fluid/electronic leak detector.
Whilst the burner is in operation close the gas service
valve. The burner should go to lockout within 1 second.
NOTE:
Refer also to the burner instruction
booklet supplied with the heater. This provides
information on how to adjust the burner,
system checks and fault finding detail.
IMPORTANT:
DO NOT use burner settings from the
burner instruction booklet. The burners are
specifically adjusted for Powrmatic heaters,
only use the settings in these instructions.
1. Check that fuel is present in the tank and at the oil filter
fitted on the front of the heater.
2. Check that fitted fire valves are open.
3. Remove the gauge connection plug located on the
bottom right of the oil pump and attach an oil gauge. (and
vent valve if the burner is on a single pipe oil feed) to the
oil pump.
4. Set the time clock and thermostat to call for heat or
complete the external control circuit.
5. Turn ON the main electrical supply and check that the
burner fan starts.
6. Note: This step is only for when a vent valve is being used.
Open the vent valve. When air free oil issues from the
vent valve close the valve and the burner will fire when
the ignition spark is present. (Note: This procedure may
need to be repeated several times if the oil line cannot be
purged of air within one ignition cycle. At the end of the
unsuccessful ignition cycle the burner will go to lockout.
Wait 2/3 minutes and then depress the red reset button
on the burner control box to restart the ignition cycle.)
7. After completion of the pre-purge period the ignition
spark will be energised and the burner oil solenoid valve
will open and the burner will light.
WARNING:
If burner ignition cannot be achieved after
2-3 attempts do not continue to recycle
through the ignition sequence but ascertain
the cause and rectify
.
