The cross sectional area of the chimney and the height must be increased at minimum 4% per 1,000 feet of elevation above sea level. The installer must maintain minimal clearances from the vent pipe to combustible material as follows: -Type “L” doublewall vent - 6 inches -Single wall vent pipe - 18 inches The chimney size should be maintained as minimal, oversize chimneys could result in the formation of condensate in the chimney. Oil Vent Piping WARNING Long horizontal vent runs, excessive number of tees or elbows or other fittings that restrict the combustion flue gas flow can result in potential flue condensation, flue gas leakage and/or carbon monoxide emissions, which can lead to severe personal injury or death. When the burner and the ELITE are properly installed, the overfire draft on the ELITE should be approximately (-)0.01”w.c to (-)0.02”w.c. Minimum Chimney Size - Oil Fired ELITE Model Flue Outlet Diameter Minimum I=B=R Chimney Size Minimum Chimney Height Rectangle Round F-25 F-30 F-35 5 inch 8" x 8" 6" 15 ft F-40 F-45 7 inch 8" x 8" 7" 15 ft 24 Venting Install a barometric control device in the vent connector as shown in Fig. 13 and 13A and adjust per the manufacturer’s instruction when excess draft needs to be relieved or when applicable codes require a device. Install an induced draft fan in the chimney for applications in which: -Excessive resistance to the flow of flue gases is excepted -The cross-sectional area of the chimney is smaller than the minimal area required -The chimney height is less than the minimal requirement When using an induced draft fan the installer should seal all vent joints and provide an interlock system for the ELITE to ensure fan operation. Oil Vent - Direct Vent Applications The installer must read and comply with the direct vent instruction outline in Triangle Tube Oil-Fired Direct Vent Instructions. The installer should give attention to the location of the ELITE prior to installation. The installer should: -Locate the unit for shortest possible vent length and the most direct path to the outside wall. -Note that flue gases will form a white plume in colder climates which may obstruct window views -Note that prevailing winds could cause nuisance lockouts, freezing of condensate and water/ice build-up may occur on buildings, plants and roofs. The installer should consider the following when determining the location of the vent termination: -Locate or guard the vent termination in a manner to prevent accidental contact by people or pets. -Vent must terminate at least 4 feet below and 4 feet horizontally or 1 foot above any window, door or gravity air inlet to the building. -Vent must terminate not less than 7 feet above grade when located adjacent to a public sidewalk. -Terminate the vent at least 6 feet from adjacent walls -The bottom of the vent termination shall be located at least 1 foot above the grade, including normal snowline. -DO NOT terminate the vent into window wells, stairwells, alcoves, courtyards or other recess area. -DO NOT terminate vent above any window, door or gravity inlet as condensate can freeze causing ice formations. Fig. 13 Damper Damper Fig. 13A Oil Fired Installations 25 Venting Gas Venting -General Requirements The venting system must be installed in accordance with: -NFPA 54 National Fuel Gas Code, ANSI Z223.1. -NFPA 211 Standard for Chimneys, Vent and Solid Fuel Burning Appliances. For installations in Canada the venting system must be installed in accordance with: -CGA / B149 Installation Code for Gas Burning Equipment. -Prior to installing the appliance into an existing chimney or venting system, the vent system should be inspected for condition and obstructions. WARNING If the inspection reveals the vent system is not safe for the intended use, it shall be repaired, rebuilt, lined, relined or replaced with a vent or chimney to conform to NFPA 211, latest edition. Failure to conduct such an inspection and/or repair could result in severe personal injury, death or substantial property damage. -No portion of the venting system shall extend into or pass through any circulating air duct or furnace plenum. -The gas venting system shall be installed, supported and spaced in accordance with their listings and the manufacturer’s instructions. Masonry and Metal Chimneys -The NFPA code book severely limits the installation of the ELITE into a masonry chimney. For applications using either interior or exterior masonry chimney a listed, approved metal chimney lining system should be used. BEST PRACTICE For any applications using an exterior chimney it is recommended that an insulated or stainless steel chimney lining system be used. NOTICE A chimney with one or more sides exposed to the outside of the structure is considered to be an exterior chimney. -The chimney shall extend at least 5 feet above the highest connected appliance flue collar. -The chimney shall extend at least 3 feet above the highest point where it passes through a roof of a b...
