inch per foot from the furnace to the vent termination. Long horizontal sections of the venting system must be supported at least every five (5) feet with metal straps to prevent sagging of the vent piping. Secure all joints in the vent connector with sheet metal screws or equivalent fasteners. Vent piping must not be inserted beyond the inside wall of the chimney flue. Power (Side-Wall) Venting – Important Note Regarding c CAUTION: Crown Boiler Company will NOT assume responsibility for damage to, and deterioration of, exterior building materials, e.g. brick, siding, clapboards, and etc., in close proximity to the vent terminal due to operation of a power vented, oil furnace. This policy is applicable regardless of the cause of sooting. Two (2) problems typically arise when power venting any oil-fired appliance. 1) Soot buildup may occur at an accelerated rate on critical components of the furnace oil burner, e.g. the primary control flame sensor (“cad cell”), the burner head, and oil nozzle. 2) Severe damage may occur to external surfaces of the structure in the event the furnace continually produces a high level of smoke in the flue gases. Excess smoke and soot can be produced for many reasons, some of which cannot be successfully controlled by the installer and the appliance manufacturer. NOTICE: Crown Boiler 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. Draft Regulator A barometric-type, draft regulator is supplied with the furnace. Installation or operating conditions that produce excess amounts of draft can reduce the heating efficiency of the furnace. The purpose of the regulator is to adjust and control the flow of flue gases from the furnace by stabilizing the amount of chimney draft to which the furnace is subjected. Generally, install the barometric draft regulator in the vent connector as close as possible to the flue outlet collar of the furnace. However, always refer to the draft regulator manufacturer’s installation instructions for application specific recommendations. 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. To obtain copies of these publications for a fee, contact the ACCA and the ASHRAE at the addresses given in Appendix A of this manual. All furnaces are tested over a range of external static pressure that simulates the airflow resistance of the ductwork, fittings, and diffusers connected to the furnace for a typical (average) duct system. The furnace blower and blower motor have been selected to work successfully against the following range of duct system resistance. Recommended range of duct system resistance for all models: 0.2 to 0.5 in. W.G. external static pressure. Due to the need to maintain an adequate supply of combustion and ventilation air, the furnace shall not be installed in small room without return air duct system. A duct the full size of the furnace return air opening shall extend to a location outside the furnace room. If the furnace is used in connection with summer air conditioning (cooling), the furnace should be installed in parallel with, or on the upstream side of, the evaporator coil to avoid water vapor condensation in the furnace heat exchanger. If the cooling unit is installed in a parallel flow arrangement, dampers (or other means used to control airflow) should be provided to prevent chilled air from entering the furnace. If such a damper is manually operated, it must be equipped with a means to prevent operation of either unit, unless the damper is placed in either the full heat or full cool position. NOTICE: Return air grilles and supply registers in the air distribution system should never be obstructed. Air Filter Mounting c CAUTION: If cutting openings in the furnace casing is required, DO NOT cut any supporting clips or angles. Cut as close to the scribed line as possible, but DO NOT cut the base clip or blower pan support angle. Lowboy furnaces are factory-equipped with permanent-type, air filters located above the blower compartment, in the rear of the furnaces. NOTICE: Horizontal / counterflow furnaces are not factory-equipped with an air filter or filter rack. Furthermore, the furnace blower compartment does not contain enough free space to permit an air filter to be mounted within the furnace casing. However, the installer should supply, or fabricate, a filter rack and mount an air filter in the return air plenum above, or u...
