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. Inform and demonstrate to the user, the correct operation and maintenance of the appliance, as explained in the Homeow ner/User Information and Routine Maintenance section of this ma[...]

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.” : Carefully read and thoroughly understand the following guidelines and w arnings before continuing w ith the installatio[...]

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 manuals provi ded by the Air Conditioning Contractors of America (ACCA) or the American Society of Heating, Refrigeration and Air Conditioning Engine[...]

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. A chimney with an i[...]

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., and condensing occurs, the chimney must be insulated around its exterior to hel[...]

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. (See Fig. 5). Fig. 5: Suggested[...]

REDUCTION OF CLEARANCES WITH SPECIFIED FORMS OF PROTECTION: Type of protection applied to and covering all surfaces of combustible material within[...]

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. The[...]

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. With the burner operat ing, use a draft gauge to adjust t[...]

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. 3. The return air duct system must equal the supply air duct system in the flow capa[...]

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. h. The resistance of the take-off and the outlet register (or[...]

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. Fig. 9: Supply [...]

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. For horizontal installations, it is recommended that return air grill[...]

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.
