Page 4: Introduction
The furnace must be installed and set up by a qualified contractor MODEL 80F Model 80F is an oil-fired upflow forced air furnace, with an output capacity range of 58,100 BTU/Hr. to 78,900 BTU/Hr. The 80F furnace equipped with a direct drive blower may be installed in both horizontal positions. -
Page 5: Horizontal Installation
2 degree slope from the oil burner casing towards the fire pot. Use shims made of noncombustible material. -
Page 6: Non-Suspended Installation
Suggestion; as a measure to prevent fuel oil from accumulating in locations other than the fire pot, as could be the case in the event of nozzle drip, install the furnace with an approximate 2 degree slope from the oil burner casing towards the fire pot. -
Page 7: Chimney Venting
If the chimney serves the furnace only, the vent should be sized at 4 inch minimum, 5 inch maximum. The table below is based on dedicated venting. If the furnace is to be co-vented with other appliances, refer to NFPA 31,... -

Page 9: Furnace Controls
CAN/CSA C22.1 Canadian Electrical Code, Part 1, and by local codes, where they prevail. The furnace should be wired to a separate and dedicated circuit in the main electrical panel; however, accessory equipment such as electronic air cleaners and humidifiers may be included on the furnace circuit. -
Page 10: Humidifier
Water or water droplets from the humidifier should not be allowed to come into contact with the furnace heat exchanger. Terminals (115 v) are provided on the ST9103 EFT control. Do not use direct drive motor connections as a source of power for 120 VAC humidifiers and humidifier transformers. -
Page 11: Oil Filter
When using an indoor oil tank, the oil filter may be installed at the tank downstream from the shut-off valve. If firing the furnace under the 0.65 gph rate, a 7 to 10 micron line filter should be installed as close to the oil burner as possible. -
Page 12: Burner Electrodes
Refer to Table A-2, page 18, for Riello oil burner air damper and turbulator settings. DESIGN Figure 5: Note A: Locate hole at least 6 inches on the furnace side of the draft control. Note B: Ideally, hole should be at least 12 inches from breeching or elbow. -
Page 13: Stack Temperature
60° and 90°F for the Model 80F, 55°F and 85°F for the Model 120F. If the venting from the furnace to the chimney is long, or exposed to cold ambient temperatures, it may be necessary to use L-Vent as the vent connector to reduce stack temperature loss to prevent condensation. -
Page 14: Circulating Air Blower
If the joining of the blower speed wiring is done in the YOUR SERVICE furnace junction box, tape off both ends of the unused wire. BELT DRIVE The HO-B Models are available with an optional belt drive blower assembly. -
Page 15: Maintenance And Service
During the routine service, inspect the general condition of the furnace watching for signs of oil leaks in the vicinity of the oil burner, soot forming on any external part of the furnace, soot forming around the joints in the vent pipe, etc. -
