Page 2: Safety Considerations
INTRODUCTION The model PO8LAA furnaces are available in sizes 105,000 Btuh through 155,000 Btuh input capacities. The furnace is shipped as a packaged unit, complete with burner and controls. It requires a line voltage (115 vac) connection to control box, a thermostat hook-up as shown on wiring diagram, oil line connection(s), adequate duct work, and connection to a properly sized vent. -
Page 3: Location
LOCATION WARNING: This furnace is not water tight and is not designed for outdoor installation. This furnace shall be installed in such a manner as to protect electrical components from water. Outdoor installation would lead to a hazardous electrical condition and to premature furnace failure. WARNING: Do not use this furnace as a construction heater. -
Page 4: Duct Work Recommendations
2. One sq. in. per 4000 Btuh of total input rating when air is brought in through vertical ducts. 3. One sq. in. per 2000 Btuh of total input rating when air is transferred through horizontal ducts. When ducts are used to supply air, they must be of the same cross-sectional area as free area of openings to which they connect. The minimum dimension of rectangular air ducts must not be less than 3 in. -
Page 5: Pre-Installation Vent System Inspection
OIL-FIRED APPLIANCES SHALL BE CONNECTED TO FLUES HAVING SUFFICIENT DRAFT AT ALL TIMES TO ENSURE SAFE AND PROPER OPERATION OF APPLIANCE. For additional venting information, refer to ANSI/NFPA 211 (Chimney, Fireplaces, Vents, and Solid Fuel Burning Appliances) and/or CSA B139 (Installation Code). -
Page 6: Oil Burner
PROCEDURE 5—OIL BURNER This furnace is supplied with a high-pressure atomizing retention head type burner (for use with not heavier than grade 2 fuel oil). The air tube length, from face of mounting plate to extreme face of end cone, should be as shown in Table 3. Table 3–Oil Burner Air Tube Length UNIT SIZE LENGTH (IN.) -
Page 7: Recommended Installation Practices And Combustion Check
PROCEDURE 2—RECOMMENDED INSTALLATION PRACTICES AND COMBUSTION CHECK In order to obtain optimum performance from oil burner, the following setup procedures must be followed: 1. A test kit (Bacharach No. 5022 kit or equivalent) to measure smoke, stack draft, over-fire CO , and stack temperatures MUST be used in order to obtain proper air band setting. -

The procedure for nozzle installation and/or replacement is outlined in Oil Burner Instruction Manual which came with the furnace. For ease of maintenance the oiling procedure for burner motor, as outline in burner manual, should be performed at the same time. After replacement of nozzle, burner should be adjusted in accordance with Combustion Check section of the instruction. - Page 10 FLUE BOX PARTITION PANEL CLEANOUT CLEANOUT COVER PORT COVER GASKET CLEANOUT COVER CLAMP BRACKET WING CLAMP INSULATION A96311 Fig. 3–Reinstalling Cleanout Port Covers A96398 Fig. 4–Removing Combustion Chamber 7.
