Eco Pacific/Super Star- Installation and Service Instructions 20173
11
Often in new installations there is a period required to purge the gas line off any air, which may be
present. If having proceeded through steps 1-6 it is determined that the gas line has been purged
off gas and the system still fails to ignite/operate correctly, refer to the Service Instructions and
wiring diagram given in the end, or contact the

Consideration should be given to the other possible causes for the equipment to fail to operate.
The PCB LED flashing at varying rates as listed below indicates some of these other problems:
2 flash = system lock out- failed to detect or sustain flame. Check that the flame sensor is
connected on to the board and positioned properly above the burner port.
4 flash = High limit or manual overheat switch opened, wait until the auto switch
closes, or if manual cut off- see if there is obstruction in the duct, open more
registers, manually reset the manual switch by pressing the black knob in
and try the ignition from the thermostat again.
5 flash = Flame sensed, and Gas valve not energised, check the gas valve and its
connections.
Steady light on = internal failure (microcontroller failure and power on self-check)
No flash- cheque the fuse, find the reason of the short circuit, rectify, and replace the 3
Amp fuse.
If the system still fails to operate, please contact Eco Pacific on (03) 9706 6228.
Once the unit is operating, set the thermostat to the temperature which satisfies your comfort
requirements.
Commissioning Procedure
1. Check the burner pressure setting. The pressure test point is as shown in
Figure
4
and is a 3/8” gland type fitting. The correct pressure for Natural Gas is 0.87 kPa
or 870 Pa for all the Super Star models in SS and HB series.
2. Have the appliance ignite by setting the room thermostat to call for heat by raising the set
point at least 2 deg C above the current room temperature.
3. Having successfully achieved ignition, after a period of 5 minutes, check the airflow at all the
registers and adjust the dampers to achieve design air quantities. The normal air delivery
temperature at the outlets should not exceed an average of 55 ºC. Maximum air delivery
temperature at the supply air connection should not exceed 60 ºC, or 55 ºC for Extra Air
models. If this requirement is not met the duct pressure balancing must be performed.
4. Check the operation of the over temperature switch by restricting the airflow (the over
temperature switch will automatically reset on cooling down). Restricting the airflow can be
achieved by blocking the area of the return air grille.
