3.5 Commissioning the Appliance

3.5.1 Pilot Ignition Check
1. Ignite the pilot light as described in the User Instructions
2. Check that the pilot flame stays alight
3. Extinguish the pilot light

2. Turn on the main burner as described in the User Instructions
3. Check that the pilot smoothly cross-lights to the main burner and that the main burner and
pilot stay alight
4. Extinguish the appliance fully

3.5.3 Pressure Check

The appliance is preset to give the correct heat inputs as listed in the technical details. No further
adjustment is necessary. Always check the inlet pressure and burner pressure.
1. Turn off the gas valve on the appliance
2. Release the screw on the Inlet Pressure test point on the gas valve and connect a manometer
3. Check that the measured pressure is as the prescribed supply pressure
4. Perform the test when the appliance is burning on full and with only the pilot alight
5. If the pressure is low, check the gas supply pipes are too a correct sizing
6. If the pressure is too high (more than 5 mbar over) the appliance may be installed, but the gas
supply company should be contacted
7. Release the screw on the Burner Pressure test point on the gas valve and connect a
manometer
8. Check that the measured pressure is as detailed in the Technical details
9. The measured value should be within +/- 10% of the described value. If this is not the case,
please contact the supplier.
Note: After checking the pressures and removing the manometers, the screws in the Pressure Test
points must be closed, and the system must be checked for gas-tightness.
