HEATER INSTALLATION
Step 10. COMMISSION THE APPLIANCE
240 VOLTS, RISK OF ELECTRICAL SHOCK!
When performing the commissioning, the appliance electrical power will need to be connected.
Exercise CAUTION as there is potential for electric shock from the exposed wiring and circuitry.
DO NOT leave the appliance unattended when power is connected and the panels are removed.
Installation and commissioning must be carried out by an Authorised person.
Wiring inside this appliance may be at 240V potential.
DO NOT test for gas escapes with an open flame.
To check and set burner pressures:
1. Refer to the appliance data plate located inside the appliance on the front of the base panel for correct gas
pressure settings.
2. Using a suitable screw driver loosen the captive Appliance
Test Point Pressure screw (ATPP) and fit the manometer,
(an electronic manometer is recommended). Refer images
for ATPP location.
3. Remove the dust cap from the regulator adjusting
screws.
4. High Pressure Setting:
Turn the appliance ‘ON’ and adjust to the highest setting, see
‘How to Operate Your Heater’ section page 19. Use a 10 mm
spanner to turn nut , lock screw with appropriate screw
driver to prevent it turning. Turning nut clockwise
increases the outlet pressure whilst turning anti-clock wise
decreases the outlet pressure.
5. Low Pressure Setting:
Turn ‘OFF’ the power to the POV by separating the
connector of the two yellow wires that power the POV. The
POV will automatically default to ‘Low Pressure’ operation.
Keep the high pressure adjusting nut stationary using a 10
mm spanner. Use an appropriate screwdriver for setting
screw . Turning clockwise increases the outlet pressure
whilst turning anticlockwise decreases the outlet pressure.
6. Replace the dust cap after pressure adjustments.
7. Reconnect the POV Yellow wires power connection.
To ensure the correct operation of the modulating valve (POV) it is necessary that the dust
Cap C is returned to its original location.
8. After re-checking the pressures, turn the appliance ‘OFF’, remove manometer and tighten the test point
sealing screw.
9. Turn the appliance ‘ON’ and ‘OFF’ a few times to confirm correct ignition and operation.
10. During the initial burn in period, some smoke and smell may be emitted. The appliance should be run on the
high position in a well ventilated room until these dissipate.
11. Check the flame pattern, see ‘Abnormal Flame Pattern’, section page 23 and page 41.
