adjustments for each model and firing rate. By
removing the burner cover and loosening the screws
that secure the air adjustment plate, the combustion air
can be adjusted. Move the adjusting plate to either
increase or decrease combustion air. When the proper
air setting is achieved, retighten the fixing screws.
Riello Balanced Flue (BF) Series
Riello burners are factory set with respect to nozzle
size; pump pressure, and turbulator adjustments for
each model and firing rate. The combustion air can be
adjusted with the burner cover on by first removing the
plastic cover on the top right hand side of the burner
cover. With a Philips head screw driver, turn the
adjustment screw clockwise to increase combustion air
or counter-clockwise to decrease combustion air.
When the combustion air is set, re-insert the plastic
