Only qualified service personnel shall perform installation and service.
1)Remove the oil burner from the shipping carton and remove any shipping materials adhering to the burner. Collect and save the burner mounting gasket and any instructions furnished with the burner.
2)If it is necessary to adjust the heating capacity of the furnace, by changing the oil burner nozzle, refer to the following directions.
a)The oil nozzle is factory installed in the oil burner. To change the oil nozzle, remove the nozzle through the front end of the burner air tube. Consult the oil burner manufacturer’s operating instructions (included with the burner) for detailed instructions on this procedure.
b)Install an appropriate replacement nozzle of the correct size, spray angle, and spray type. Refer to the Specification Sheets, in Appendix C of the furnace instruction manual, for nozzle recommendations.
3)On highboy furnace models, remove the burner access panel. This panel will be the upper access panel on the front of the furnace. On lowboy models, remove the front access panel. On horizontal / counterflow models, the burner is mounted on the front surface of the furnace.
4)Remove the three (3), 5/16 in. brass hex machine screw nuts and the three (3) steel flat washers from the threaded studs protruding through the burner mounting plate on the furnace. Retain this hardware for later reuse.
5)Rough handling of the furnace may occur while in transit. Under some conditions, the combustion chamber can shift out of position. The chamber should seat properly on the base of the heat exchanger. Check for proper alignment of the burner air tube with the circular opening in the combustion chamber and trial fit the burner to check the insertion depth of the oil burner into the combustion chamber. It may be necessary to remove the burner mounting plate to get sufficient access to the chamber.
The end of the burner air tube should be inserted no farther than 1/4 inch back from the inside surface of the combustion chamber, refer to Figure 1. DO NOT allow the burner head, at the end of the burner air tube, to physically touch or protrude into the chamber. High temperatures in the combustion chamber can result in damage to the tube, the burner head, or both. A distance greater than 1/4 inch back from the inside chamber wall may cause oil spray impingement on the combustion chamber wall and subsequent sooting and the formation of carbon char deposits.
