Page 10: Chimney Inspection
Chimney Inspection The chimney, vent, or any passageway for the stack gases to flow to the outdoor atmosphere is a very important part of the heating system. No furnace, regardless of the efficiency of the design, can perform satisfactorily when the chimney to which it is connected is inadequate or in poor condition. -
Page 11: Power (Side-Wall) Venting - Important Note Regarding
NOTICE: Thermo Products recommends the use of a chimney to vent residential oil furnaces. If a power venter must be used, it is the responsibility of the installer and power venter manufacturer to design, assemble, and demonstrate proper operation of the power venting system with the furnace. -
Page 12: Duct Work And Air Conditioning
Duct Work and Air Conditioning Design and installation of the duct system should follow the current guidelines of the Air Conditioning Contractors of America (ACCA) or the American Society of Heating, Refrigeration and Air Conditioning Engineers, Inc. (ASHRAE). Refer to the Residential Duct Systems, Manual D, from the ACCA, and the ASHRAE Handbook Fundamentals volume, from ASHRAE, for recommended practices in duct system design and installation. - Page 13 On the highboy furnace, it is necessary to cut the return air opening in the lower side, or rear, of the casing depending upon the needs of the specific installation, refer to Figure Figure 3: Cutaway view of fan section of a typical highboy furnace. The side casings have each been pre-punched with four (4), square, knockout openings for use in locating the proper position for the return air filter rack.

Page 14: Electrical Connections
Electrical Connections NOTICE: All field wiring must conform to local, state, and national installation codes. A disconnecting switch equipped with overcurrent protection rated at 15 A. (e.g. a time delay-type fuse or inverse time, circuit breaker) should be installed in the service line for shutting down and protecting the furnace and electrical system. -
Page 15: Combustion Chamber
Generally, a room thermostat should be set at the lowest temperature that is comfortable to the building occupants. This will result in the lowest cost to heat the building. Combustion Chamber The furnace combustion chamber is a hollow, circular cylinder sealed at the bottom end and open at the top end. - Page 16 Install an appropriate replacement nozzle of the correct size, spray angle, and spray type. Refer to the Specification Sheets, in Appendix C of this manual, for nozzle recommendations. The furnace may have been handled roughly while in transit. Under some conditions, the combustion chamber can shift out of position.

Page 23: Furnace Limit And Blower Controls
Furnace Limit and Blower Controls All furnaces are equipped with a thermostatic high temperature limit. The high temperature limit is set such that it does not permit a supply (discharge) air temperature above 200ºF. The thermostatic fan control should be set so the greatest fuel utilization efficiency of the furnace is obtained. -
Page 24: Room Thermostat
Should airflow be restricted, the furnace might cycle on and off too frequently or become inoperative. The fan timer board will indicate this limit activation sequence by the flashing of the red LED. When this LED is flashing the call for heat is disrupted and the blower will run continuously until the limit has been satisfied. - Page 25 4) Demonstrate how to operate (turn on and off), the heating system and, if properly equipped, the cooling system and the circulating air blower. 5) Show the location of the oil primary safety control in the furnace. Describe when and demonstrate how to depress the oil primary reset button.

SERVICE Troubleshooting c WARNING: When testing electrical equipment, always follow standard electrical safety procedures. Before beginning these troubleshooting procedures, always review these basic points. 1) Check for 120 VAC power to the furnace. If there is no voltage, check the disconnecting switch for circuit breaker trip or blown fuses. - Page 27 2) Confirm there is 120 VAC at the junction box and the oil furnace control terminal S1. 3) Confirm the room thermostat is wired correctly, set on the “HEAT” mode, and “calling for heat”. 4) For all primary controls, lockout can be confirmed by measuring voltage from the oil primary safety control to the burner motor.
- Page 28 C. Symptom: Burner short cycles on high limit thermostat, but does not “lock out” on oil primary safety control. Items to check: 1) Open dampers or registers in the air distribution system. Clear any duct system restrictions. 2) Inspect and clean all air filters in the air distribution system. 3) Inspect blower for interference with rotation or locked rotor condition.
- Page 29 6) Measure the draft at the point where the vent connector attaches to the heat exchanger flue pipe. With the burner operating, the stack draft should not exceed 0.05 in. W.G. If the stack draft has been adjusted above this value to give the proper overfire draft, the heat exchanger will require cleaning.
