Thermo Products OL6RA072D48(B/R) J. Oil Filter, K. Electrical Wiriing, Maximum, Minimum, Assembly

J. OIL FILTER:

It is strongly recommended that an oil filter assembly be installed in the oil supply line to the unit. This filter should have the capacity to trap a 40-50 micron particle.

The filter cartridge should be replaced at least once a year. The filter body should be thoroughly cleaned before installing a new cartridge.

K. ELECTRICAL WIRIING:

: This appliance must be grounded in accordance with local codes, or in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70-1999, or the latest edition.

All wiring must conform to the provisions of local codes or, in the absence of local codes, with the provisions of the National Electrical Code, ANSI/NFPA 70-1999, or the latest edition, and this instruction manual.

This appliance requires 120 VAC, 60 Hz, single-phase power. Refer to Table 10 for typical electrical current draws of the individual appliance motors, recommended sizes for over-current and short circuit devices, and minimum recommended field wiring sizes. Electrical service must be brought to the unit from a circuit breaker, or fused disconnect switch, in accordance with local codes. The disconnecting switch must be located reasonably close to and within sight of the unit. Care must be taken to ensure correct polarity when wiring the furnace.

Two-wire service, one “hot” lead (L1) and a common (L2), plus a ground conductor, is required. Connect power to the appliance control system at the junction box in the burner compartment. (A knockout fitting is provided on the exterior of the burner compartment for this purpose.) A ground wire must be connected to the grounding wire in the junction box.

Field wiring of power circuits to the appliance should consist of copper conductors rated for at least

15 amp service with an insulation temperature rating of at least 75°C temperature rise. Depending upon code requirements, rigid or flexible conduit is recommended, and may be required. Connect the electric power supply as shown in the wiring diagram located on the inside of the front door.

Typically, control wiring between the appliance and the indoor thermostat, and if used, electronic air cleaner or humidifier, will be required. Field wiring of control circuits should consist of copper conductors rated for at least 15 amp service with an insulation temperature rating conforming to Type T wire, 35°C temperature rise. Depending upon code requirements, rigid or flexible conduit is recommended, and may be required. Make connections between the thermostat, and electronic air cleaner or humidifier (if used), and the fan control module, inside the vestibule. Consult the wiring diagram for the appropriate connection points on the thermostat and the fan control module.
