1 I. SAFETY SECTION This page and the following contains various w arnings and cautions found throughout the Oil Furnace Manual. Please read and comply with the statements below. c WARNING AND CAUTIONS: c WARNING: This furnace is not to be used as a construction heater.
2.
3 The entire text of these instructions must be read and understood, before installing the appliance. It is the installer's responsibility to do the following: 1.
4 b. Non-combustible material: “...material that is not capable of bei ng ignited and burned; such as material consisting entirely of, or a combination o f, steel, iron, brick, concrete, slate, asbestos, glass, and plaster.
5 II. GENERAL INSTRUCTIONS - READ BE FORE START OF INSTALLATION 1. The heating output capacity of the furnace proposed for installation should be based on a heat loss calculation made according to the.
6 A. CHIMNEY : The furnace must be connected to an adequate chimney or an approved vent in accordance with these instructions. An adequate chimney is one that is s ealed and lined with the capability of producing a (-).04" WC flue draft and having the capacity to handle the amount of stack gases that are introduced into it.
7 and reduce the stack gas temperature loss. Insulation may be added around the liner for further temperature stability. If the chimney is on the home's exterior or passes through a sizable, unheated area of the building, such as a porch, high ceiling atti c, etc.
8 Fig. 4: Proper insertion of the vent connector in the chimney . 5. PROPER CHIMNEY BOTTOM LEVEL: In cases where the chimney extends to the basement floor, the draft can usually be improved by filling the base of the chimney with sand to within 12 inches of the vent connector pipe after relocating the clean-out door.
9 Fig. 6: Suggested method to accommodate vent connector passage through a wall composed of a combustible material. Fig. 7: Alternate constructions that allow reduced clearances to combustible materials.
10 The vent connector pipe between the furnace and chimney s hall be of equal diameter as the flue outlet of the furnace. The vent connector pipe must be made of 24 gauge (or thicker) corrosion-resistant steel. The vent connector pipe should be as short as possible and inst alled so that it has a continuous rise from the furnace to the chimney.
11 The combustion air inlet can be installed through the either the lower left side casing knock-out or the lower right side casing knock-out. C. DRAFT REGULATORS: A draft regulator is supplied with the furnace and should be installed according to the regulator manufacturers recommendations.
12 2. To reduce the transmission of vibration and noise to the duct system and to reduce flexure of the duct system due to thermal expansion and c ontraction, it is recommended that flexible joints be installed at the supply and return duct connections to the unit.
13 The ASHRAE Handbook – Fundamentals is an excellent source of duct system design principles and pressure drop data. Conversely, for a specified type of fitting, it is also possible to determine the required size or diameter of the component for a specified pressure drop and flowrate.
14 8. As a final step in the installation, the appliance mu st be adjusted to deliver a temperature rise within the range of 50° to 80°F. Adjust the blower moto r speed to obtain a temperature rise within the acceptable range. The required blower speed w ill depend on the airflow resistance of a supply and return air duct systems.
15 E. Air Filters Filter Installation The OD6 comes with (2) two 18-3/4” x 12-3/4” reusable filters. A “W” style filter rack is shipped with the furnace for placement of the filters inside the retu rn air plenum. Access to the filters is through the removable blower door.
16 F. LIMIT POSITION AND LOCATION c WARNING: The predetermined limit locations on all of t he Thermo Pride oil fired furnaces have been tested and approved by Thermo Products, LLC.

22 I. OIL TANK AND PIPING: : All local codes and ordinances take precedence w ith regard to selection and installation of oil storage tank and oil supply (and return) lines.
23 When the oil tank is located below the level of the burner , it is necessary to “lift” the oil to the burner. A return line should be connected between the fuel pump and tank. This requires insertion of the "by-pass" plug into the fuel pump.

37 N. STARTUP PROCEDURES: A. Heating System 1. Initial Startup: : Turn off pow er to furnace. Before the oil piping system is placed into servi ce, it must have been leak tested by a qualified heating contractor. : For initial start-up of the appliance after installation, it may be necessary to purge the air out of the oil line.
38 To Turn Off Oil to Appliance: i. Set the thermostat to the lowest setting and set the operating mode switch to “OFF”. ii. If s ervice is to be performed, turn off t he electrical power to the appliance. iii. Turn the manual oil shutoff valve to the “OFF” position.
39 Figure 19: Preliminary A djustment of Burner Air Band and A ir Shutter i. When ignition is established, make a prelim inary burner air adjustment to attain a clean combustion flame.
40 The setting of the fan output according to the installation should be done only through the air damper. Should you want to adjust the setting of the combustion head, with the burner running, turn t.
41 Figure 22 1 st STAGE ADJUSTMENT: Adjustment of air shutter: place the small plug (9) of the economizer (10) into the position I (Item A). In this way the burner will remain permanently in the 1 st stage. Loosen the nut (2), turn the screw (3) until the air s hutter (1) reaches the position desired.
42 ii. CARBON DIOXIDE (CO 2 ) OR OXYGEN (O 2 ): Take a CO 2 sample from flue passageway. It is possible to achieve readings of up to 14% CO 2 (or 2% O 2 ), but it is better to have a slightly lower CO 2 (or higher O 2 ) reading with zero smoke measured.
43 a. With the oil shut off, remove the 1/8 in. NPT threaded pipe pl ug located on the lower rear side of the oil pump, refer to Figure 22. Attach a pressure gage, capable of measuring pressure in pounds per square inch gage, PSIG, in this opening, on t he discharge side, of the oil pump.
44 5. Checkout Procedure: Before any system of oil piping is finally put into serv ice, it shall be carefully tested to assure that it is “gas-tight”, as indicated in the Heating System Initial Startup section of this manual.
45 III. USERS INFORMATION SECTION A. OIL SUPPLY: Do not allow the fuel tank to run comp letely empty. During the summer, keep the tank full to prevent condensation of moisture on the inside surface of the tank. If the fuel tank runs completely dry, it may be necessary to purge the li nes of trapped air.
46 D. STARTING THE BURNER: 1. Turn the main service switch to "OFF" position. 2. Set thermostat substantia lly above room temperature. 3. Open shut-off valves in oil supply line to burner.
47 IV. INSTALLER'S INSTRUCTIONS TO USER: After completing the installation, the installer shall inform and/or demonstrate to the homeowner the follow ing items: 1. The location of these instructions. The instruct ions must be kept along with instructions for any accessories in the plastic pouch with the appliance.
48 V. DEALER MAINTENANCE: SAFETY DURING SERVICING AND INSPECTION : Personal injury or property damage could result from repair or service of this appliance by any one other than a qualified heating contractor. The user may only perform the activities described in the Homeowner/User Routine Maintenance section of this manual.
49 B. HEAT EXCHANGER: c WARNING: A qualified heating contractor must clean the heat exchanger. At least once a year, inspect the heat exchanger for evidence of corrosi on, pitting, warpage, deterioration, and carbon (soot) build-up.

51 4. Operational Check: c CAUTION: Before troubleshooting, familiarize yourself with the start up and check out procedures NOTICE: After reassembling the appliance, check for fuel oil leakage from the supply piping. a. Check proper operation of the ignition system and for proper combustion.
52 Figure 26: Location of Supply/Return A ir Filter Filter replacement: To ensure an adequate replacement filter is selected, shoul d the filter require replacing, refer to Table 4, in Air Filters section of this manual, for the minimum filter areas required for different types of available filters.
53 ON SHUTDOWN: 1. Close oil supply (or manual shutoff) valve. 2. Disconnect all electrical power to the unit. 3. Fill the oil tank to reduce water condensation in the tank. 4. If the shutdown period will exceed one heating s eason, an oil stabilizer should be added to the oil tank.
54 VI. HOMEOWNER/USER INFORM ATION AND ROUTINE MAINTENANCE: c WARNING: Never burn garbage or refuse in th is appliance. Never try to ignite oil by tossing burning papers or other material into the combustion chamber. c WARNING: Oil-fired appliances produced by Thermo Products are designed for burning No.
