G. BURNER INSTALLATION: NOTICE: Remove all cardboard packing from around chamber before installing burner. The oil burner will mount on three stud mounting bolts on the lower mounting plate covering the opening in the front of the heat exchanger. The end of the burner tube should be inserted no further than 1/4 inch back from the inside surface of the combustion chamber. A distance further than 1/4 inch back from the inside chamber wall may cause impingement and sooting. This unit is

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 ac

Qualified service personnel must perform all installations and services. The following are common chimney requirements necessary for the furnace to operate correctly: A masonry chimney serving a Thermo Pride oil fired furnace must comply with local codes and NFPA Standard for Chimneys, Fireplaces, Vents, and Solid Fuel Burning Appliances (NFPA211-1996 or latest edition). 1. PROPER CHIMNEY SIZE: The inside area of the chimney liner should equal, at minimum, the area of the vent pipe

occurs, then insulating the vent connector and/or reducing the efficiency of the furnace may have to be done to raise the chimney temperature. More detailed information may be obtained from the latest edition of the ASHRAE HVAC Systems and Equipment Handbook. 3. PROPER CHIMNEY HEIGHT: The chimney shall terminate at least 3 feet above the highest point where it passes through the roof of a building and at least 2 feet higher than any portion of a building within a horizontal distance
Summary of the content on the page No. 11
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 be free of any obstructions, such as loose brick, broken pieces of

NOTE: On the OL6 it is possible to rotate the flue elbow (which is factory installed for vertical discharge) 90° counter clockwise from the vertical position to adapt to various venting systems. Notice: Blocked Vent Switch Installation The blocked vent switch kit must be installed to comply with CAN STD B140.4 where applicable. For installation instructions see AOPS2687 kit. c CAUTION MUST BE TAKEN NOT TO EXCEED 90° ROTATION (OF THE FLUE ELBOW) . ROTATION OF FRONT FLUE ELBO

To measure the flue draft, punch a small hole in the vent connector pipe as close to the furnace as possible and always before the draft regulator. Note: Draft over fire may be positive for high fire applications but not to exceed (+).02" WC. D.

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 flow rate. 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 v

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.
