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 Homeowner/User Information and Routine Maintenance section of this manual. 2. Inform the user of the hazards of flammable liquids and vapors and to remove such liquids and vapors from the vicinity of the appliance.

II. GENERAL INSTRUCTIONS - READ BEFORE 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 provided by the Air Conditioning Contractors of America (ACCA) or the American Society of Heating, Refrigeration and Air Conditioning Engineers, Inc. (ASHRAE). 2. All local codes and/or regulations take precedence over the instructions in this manual and should be followed acco

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 sealed 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 internal construction of corrosion resistant tile, stainless steel, or some other material that will withstand flue gas temperatures up to 900°F is requ

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 attic, etc., and condensing occurs, the chimney must be insulated around its exterior to help the flue hold its temperature. Also, check to see if the chimney is too large for the furnace and other appliances connected to it. If so, reduce to p

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 method to improve chimney draft. 6. TIGHT JOINTS: All joints of the chimney must be tightly sealed. The inside of the chimney should

The vent connector pipe between the furnace and chimney shall 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 installed so that it has a continuous rise from the furnace to the chimney. The horizontal length of a connector to a natural draft chimney or vent serving a single appliance shall not be more than 75 percent of the height of th

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 operating, use a draft gauge to adjust the regulator to the proper setting. (refer to the instructions enclosed with draft regulator to adjust to the proper setting). When the burner a

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 contraction, 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 capacity (CFM) for a given pressure drop. Use a supplier's catalog for proper sizing of outlet and return air registers and grills to ensure that the

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 return grill) should then be summed together to determine the total pressure drop for each branch. This value should be close to the assumed valu

8. As a final step in the installation, the appliance must be adjusted to deliver a temperature rise within the range of 50° to 80°F. Adjust the blower motor speed to obtain a temperature rise within the acceptable range. The required blower speed will depend on the airflow resistance of a supply and return air duct systems. Fig. 9: Supply air duct sizing Example The RETURN AIR DUCT SYSTEM should equal the warm air duct system in airflow capabilities. NOTE: When a return registe

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 return air plenum. Access to the filters is through the removable blower door. For horizontal installations, it is recommended that return air grill filters be installed for homeowner access. 19.125" 3.000" Fig. 10: A typical filter rack and dimension
