[. . . ] POWER VENTER SYSTEM Model: PVO-300, PVO-600 Included is one ETL and cETL listed Power Venter to be used primarily with a single 120VAC controlled oil fired furnace, boiler, or water heater. The PVO may be used to common vent multiple appliances with the addition of a Control Kit. Please consult Field Control's Technical Support for other options. TYPICAL VENTING SYSTEM COMPONENTS One PVO Series Power Venter with pre-wired controls; adjustable post purge relay timer, adjustable draft proving switch, direct access terminal blocks, and piping tee for multiple appliance systems. [. . . ] DO NOT install if any damage is apparent. Refer to unit sizing chart to check proper venting sizing. Location of the termination of the venting system should be installed in accordance with the National Fuel Gas Code, A. N. S. I. Z233. 1, manufacturer's recommendations, and/or local codes which are applicable. See the following requirements or refer to Diagram A for typical locations. The exit termination of mechanical draft systems shall not be less than 7' above grade when located adjacent to public walkways. A venting system shall terminate at least 3' above any forced air inlet located within 10'. The venting system of other than a direct vent appliance shall terminate at least 4' below, 4' horizontally from, or 1' above any door, window, or gravity air inlet into the building. When venting oil fired equipment with a Field Control's CAS-2 series Airboot® kit, the intake air hood can be mounted within 12 inches of the power venter exhaust. The vent termination of a direct vent appliance with an input of 50, 000 BTU/Hr or less, shall be located at least 9" from any opening through which vented gases could enter the building. With an input over 50, 000 BTU/Hr, a 12" termination clearance shall be required. The vent termination point shall not be installed closer than 3' from an inside corner of an L-shaped structure. The vent termination should not be mounted directly above or within 3' horizontally from an oil tank vent or gas meter. The bottom of the vent terminal shall be located at least 12" above finished grade. CONNECTING VENTER TO APPLIANCE The venting system should be installed and supported in accordance with the National Fuel Gas Code ANSIZ223. 1, or in accordance with any local codes. A vent pipe connector shall be supported for the design and weight of the material employed, to maintain clearances, prevent physical damage and separation of joints. A vent pipe increaser or reducer may be required for connecting the venter to the vent system. Smaller vent pipe sizes than a chimney-vented system may be used for the vent system. Route the vent pipe from the appliance to the venter using a minimum number of elbows as possible. The horizontal section of the vent pipe should have a slight upward slope from the appliance to the venter. For clearances to combustible materials, multiple appliance venting and other installation requirements, refer to the National Fuel Gas Code ANSIZ223. 1, and/or any applicable local codes or appliance manufacturer's installation instructions. GENERAL WIRING INSTRUCTIONS CAUTION: Disconnect electrical power before wiring power venter!The PVO is designed to be used with appliances with 120VAC control systems. [. . . ] If appliances are equipped with high and low flame control or flame modulation, check for proper main burner operation at low flame. Test for exhaust gas spillage at the draft hood or the barometric draft control after approximately 5 minutes of main burner operation. Use a draft meter or flame or smoke from match, candle or cigarette. If spillage occurs, adequate air is not available. [. . . ]
