1 SAFETY REGULATIONS 1.1 WARNING SAFETY LABELING AND WARNING SIGNS The words DANGER, WARNING AND CAUTION are used to identify the levels of seriousness of certain hazards. It is important that you understand their meaning. You will notice these words in the manual as follows: DANGER Immediate hazards that WILL result in death, serious bodily injury and/or property damage. WARNING Installations and repairs performed by unqualified persons can result in hazards to them and to others.
2.2 2 INSTALLATION The unit is shipped with a burner and its controls. It requires a 115VAC power supply to the control panel and thermostat hook-up as shown on the wiring diagram, one or more oil line connections, suitable ductwork and connection to a properly sized vent. All local and national code requirements governing the installation of oil burning equipment, wiring and the flue connection MUST be followed. Some of the codes that may apply are: CSA B139: Installation code for oil burning equipment.
Refer to the detailed instructions and wiring diagrams 2.4 VENTING supplied with the BVSO for the installation and wiring procedures. The length of wires supplied with the unit is such that the safety device must be installed between the flue outlet of the appliance and the draft regulator, as indicated in the instructions. WARNING Poisonous carbon monoxide gas hazard. Never install a hand operated damper in the vent pipe.
2.6.1 CONTAMINATED COMBUSTION AIR Installations in certain areas or types of structures will increase the exposure to chemicals or halogens that may harm the furnace. These conditions will require that only outside air be used for combustion. The following areas or types of structures may contain or be exposed to certain substances, potentially requiring outside air for combustion: a. b. c. Commercial buildings; Buildings with indoor pools; Furnaces installed near chemical storage areas. 2.
3.2 WARNING Poisonous carbon monoxide gas hazard. 1. Install the evaporator coil on the supply side of the furnace ducting ONLY. An evaporator coil installed on the return air side of the ducting can cause condensation to form inside the heat exchanger, resulting in heat exchanger failure. This in turn, can result in death, bodily injury and/or property damage. A clearance of 15 cm (6") is required between the bottom of the coil drain pan and the top of the heat exchanger.
3.3.3 COMBUSTION CHECK 3.3.6 IMPORTANT 1. The heat exchanger metal surfaces may have oil and the baffle insulation also contains binders. These products will burn or evaporate when the unit operates for the first time. Because of that, the smoke reading may be skewed during the first minutes of operation. Therefore, the unit must operate during at least 60 minutes before taking any readings to adjust the combustion quality. Let the unit cool down before making any adjustments. 2.
3.3.9 To decrease the airflow, loosen setscrew on the inner half of the motor pulley, looking at the shaft end. Turn the inner half of the pulley clockwise. After the adjustment, the setscrew must be tightened on the flat side of the motor shaft. Be sure that the blower belt tension is adequate. (Refer to the maintenance section). 1. 2. 3. Figure 1 – Pulley adjustment 4. 5.
4.2 4 MAINTENANCE WARNING Electrical shock hazard. Turn OFF power and fuel to the furnace before any disassembly or servicing. Failure to do so can result in death, bodily injury and/or property damage. Preventive maintenance is the best way to avoid unnecessary expense and inconvenience. Have your heating system and burner inspected by a qualified service technician at regular intervals.
4.7 MOTOR LUBRICATION Belt tension verification Do NOT lubricate the oil burner motor or the direct drive blower motor as they are permanently lubricated. 4.8 Ideally, belt tension should be checked with an appropriate gauge. If such a tool is not available, the tension can be checked by applying pressure to it in the centre between the pulleys. The belt displacement should be about 25.4 mm (1") (refer to Figure 4.1). Adjust the belt by using the two adjustment screws located near the motor base.
