STARTING THE APPLIANCE

2Remove plastic cover from the burner casing (there is no plastic cover on the Riello burner). Fit a suitable pressure gauge to port (A) on the oil pump.

Adjust the air shutter (L) and pump pressure

(B) as shown in the table opposite. The burner should ignite following a pre-ignition period of approx. 15 seconds.

Boiler lockout indicator on:

If the burner fails to establish a normal firing pattern or flame failure occurs the flame monitoring photocell mounted in the burner body will alert the burner control box to shut the burner down and provide a safe lockout state indicated by the illumination of the lockout indicator (E).

Wait 2 minutes then press the lockout reset button (D) to initiate another start sequence.

Repeat procedure until a flame is established.

3Start and run for 3 minutes then switch off. Check for after-spurting from the nozzle, indicated by oil saturation on the combustion head (F).

If after-spurting occurs: Release the burner retainers.

Remove the burner, combustion head (F). and electrodes, hold the burner vertical to unscrew the nozzle and fill the nozzle

holder with oil.

Refit nozzle, electrodes, combustion head (F) and the burner.

Restart and run for 3 minute intervals until after-spurting stops.

4 Start and run for 20 minutes.

Remove sampling point plug (K) to check

the smoke reading is between 0-1. If the

smoke level is above 1, check the combustion

settings are correct and the oil nozzle is in

Note; smoke readings may be inaccurate until the smoke from burning organic binder in the access door insulation has ceased.

Check the CO2 levels and adjust the air shutter (L) setting according to the table opposite.

Check the flue gas temperature is close to the values shown in the table.

If the flue gas temperature is too high and the baffles are correctly fitted, then reduce the oil pump pressure (B) 5-10p.s.i. to compensate for nozzle variations.

Turn off the electrical supply.

Isolate the oil supply to the burner.

Remove the oil pressure gauge.

Refit the blanking plug (A).

Check and rectify any oil leaks.

5Switch on the oil supply. Switch on the electrical supply.

Restart the boiler and run for 5 minutes.

Recheck the CO2 levels and if required, adjust the air shutter setting (L) to obtain the correct CO2 level.
