It is not necessary to use bird screenswith the PVT-HL termination.Terminate at least 12" (300mm) above grade or above snow line.Terminate at least 7' (2.1m) above a public walkway, 6' (1.8m)from the combustion air intake of any appliance, and 3' (0.9m)from any other building opening, gas utility meter, service regulator etc.Terminate at least 3' (0.9m) above any forced air inlet within10' (3m) , 1' (0.3m) below, 1' (0.3m) horizontallyfrom or 1' (0.3m)above any door, window, or gravity air inlet into any building perNational Fuel Gas Code ANSI Z223.1/NFPA 54.Slope the horizontal vent 1/4" upwards for every 12" (300mm)toward the termination.Use a condensation drain if necessary.In the Commonwealth of Massachusetts a carbon monoxide detectoris required for all side wall horizontally vented gas fuel equipment.Please refer to Technical Bulletin TB 010606 for full installationinstructions.As illustrated on the left, make sure to keep a distanceof 3' (0.9m) or wider between the intake and exhaustwhen installing the vent piping.Terminate at least 6' (1.8m) from the combustion airintake of any appliance, and 3' (0.9m) from any otherbuilding opening, gas utility meter, service regulator etc.Enclose exterior vent systems below the roof line to limitcondensation and protect against mechanical failure.When the vent penetrates a floor or ceiling and is notrunning in a fire rated shaft, a firestop and support isrequired.When the vent termination is located not less than8' (2.4m) from a vertical wall or similar obstruction,terminate above the roof at least 2' (0.6m), but notmore than 6' (1.87m), in accordance with the NationalFuel Gas Code ANSI Z223.1/NFPA 54.Provide vertical support every 3' (0.9m) or as requiredby the vent pipe manufacturer's instructions.A short horizontal section is recommended to preventdebris from falling into the water heater.When using a horizontal section, slope the horizontalvent 1/4” upwards for every 12” (300mm) toward thetermination to drain condensate.**1' minimum recommended,but not required.* Not supplied with water heater,order separately.When choosing intake and exhaust terminations, you must use thesame type of elbow (i.e. both 90° elbows).This will help with proper combustion by putting both terminations inthe same pressure zone.When choosing intake and exhaust terminations, you must use thesame type of elbow (i.e. both 90° elbows).This will help with proper combustion by putting both terminations inthe same pressure zone.Insert BirdScreen* inEnd of90 ElbowInsert Bird Screen*in End of 90 Elbow3” Min.Vent Pipe Installation▲The illustration is an example.
