Thermo Products Comprehensive Oil Burner Nozzles Chart -

All installations and services must be performed by qualified service personnel.

STANDARD BURNER NOZZLES: The OL2, OH2, OC2 and OC1, along with the OL33, OL37 and OL39 have the nozzles already installed in the burners. The balance of the oil units has the nozzles shipped as loose items with the furnace. Below is a chart showing the heating capacity of the furnace for each approved nozzle size.
