DIRECT VENT OIL BURNERS
Riello Burners - All Riello direct vent burners are shipped with the nozzle for the 3 section boiler
installed. A separate nozzle is included in the burner carton for the 4 section and 5 section boilers.
See the burner set up page for the appropriate burner settings. Final burner adjustments must be
made using proper test equipment.
Boilers supplied with Riello burners will also be supplied with a 3” to 4” galvanized adapter.
The adapter is to be fastened directly to the flange opening on the burner cover using three sheet
metal screws.
The Riello BF5 burners for use with direct vent systems are shipped with the controls, which provide
pre and post purge. Pre purge is provided to ensure clean starts under all conditions. Post purge is
provided to ensure that the boiler fires at maximum efficiency and dependability throughout the
heating season. Post purge timing is variable. The factory set post purge timing should be set at
approximately 45 seconds. Post purge times in excess of 60 seconds will cause the Honeywell
Aquastat to lock out on an error code.
MAINTENANCE
The entire heating system, including the venting system must be checked annually by a qualified
heating professional.
