A CAUTION A CAUTION Model No. O23V-70/90/105/120 O23V-140/154 Installation of Lennox oil-fired furnaces must conform with the National Fire Protection Association Standard for the Installation of Oil Burning Equipment, NFPA No. 31, the National Electrical Code, ANSI/NFPA No.70 (in the U.S.A.), CSA Standard CAN/CSA-B139 (in Canada), Installation Cod[...]

Neither the nozzle setting nor the airadjustments are fac- tory set. The furnace is firetested andthe limit control is checked to make sure it functions properly; no factory set- tings are made. During installation, the furnace must be "set up." The installing dealer/contractor must have and use proper test equipment in order to correctly[...]

A, WARNING I A WARNING CAUTION NOTE - Oil burning equipment may be vented into an ap- proved masonry chimney or type L vent. (Type L vent is similar in construction to type B gas vent. Type L vent car- ties a higher temperature rating and is constructed with an inner liner of stainless steel, rather than aluminum.) Prior to installation of unit, ma[...]

16. Where condensation of vent gas is apparent, the vent should be repaired or replaced, Accumulation of con- densation in the vent is unacceptable. 17. Vent connectors serving this appliance shall not be connected into any portion of mechanical draft sys- tems operating under positive pressure, 18. Keep the area around the vent terminal free of sn[...]

Air from an Adjacent Space If the confined space housing the furnace adjoins space categorized as unconfined, air can be brought in by provid- ing two permanent openings between the two spaces. Each opening must have a minimum free area of 1 square inch (6.4 square centimeters) per 1,000 Btu (293 W) per hour of the total input rating of all fuel-fi[...]

One-Pipe Systems CAUTION The burner is shipped with fuel pump set for one-pipe op- eration. For one-pipe systems, the oil supply pipe is con- nected to the inlet tap on the pump. A one-pipe system should only be used where there is gravity oil flow to the pump and the pipe is not run at any point above the oil level in the tank. 1. Connect the inle[...]

IMPORTANT 2, Install the room thermostat and make wire connec- tions to the fan control board. Avoid installing thermo- stat on an outside wall or where it can be affected by radiant heat, Set the adjustable heat anticipator on thermostat according to the wiring diagram sticker pro- vided on unit, 3, Install a separate fused disconnect switch near [...]

ADJUST The ADJUST pins allow the motor to run at normal speed, approximately 15% higher than normal speed, or 15% low- er than normal speed. Table 6 gives three rows--NORM, (+), and (-) with their respective CFM volumes. Notice that the normal <'NORM" adjustment setting for cool speed position C in table 6 is 800 CFM The "(+)"[...]

Continuous Fan When the thermostat is set for "Continuous Fan" operation and there is no demand for heating or cooling, the blower control will provide 50% of the COOL CFM selected.

Before starting unit, make sure the oil tank is adequately filled with clean No, 1 or No, 2 furnace oil, NOTE - Water, rust or other contaminants in oil supply sys- tem will cause malfunction and failure of the internal parts of the fuel pump. CAUTION 1, Set thermostat for heating demand and turn on electri- cal supply to unit, 2, Check initial air[...]

causing the unit to start sooting/smoking, Things which might affect combustion include a nozzle going bad, draft that changes during different climatic condi- tions, dirty oil, dirt obstructing the air inlet, etc. To build in a "window of operation," set up the burner to be 2% less in CO2, For example, if you find a reading of 12% CO2, a[...]

4, Action: Established flame fails Response: • Burner motor is de-energized and oil primary con- trol goes into recycle mode, • If the fan off delay is longer than the recycle timing, the heat fan continues to run through the next trial for ignition. 5. Action: Limit Switch Opens Response: • Oil primary control shut off the burner. • Circul[...]

Source Procedure Causes Correction Burner Blown fuse Replace the fuse. Place the trouble light between the black and white leads to the burner motor. No light indicates that no power is getting to the motor. Place trouble light between the black and white leads to the blower motor. Light indicates power to the motor and burner fault. Binding burner[...]

Source Procedure Causes Correction Burner Motor Low line voltage Motor does not come up to speed and trips out on overload. Turn off power and rotate blower wheel by hand to check for binding or excessive drag. Check voltage at power source. Correct cause of voltage drop or the call power company. Pump or blower overloading motor Correct cause of o[...]

Source Procedure Correction Power Locate and secure connection. If voltage fluctuates, fault is in the power source. Recheck voltage at the power source. Causes Loose wiring connection Low or fluctuating line voltage Call power company.
