Mortar or Silicone Caulk Vent Pipe From Water Heater Pipe Coupling Horizontal Vent Installation 2' x 2' Sheet Metal Shieldon Brick or Masonry Walls Once the vent terminal location has been determined, make a hole through the exterior wall to accommodate the vent pipe. Vent pipe must exit exterior wall horizontally only. Vent Terminal with 1¼2" Mesh Protective Screen Inside Insert a small length of vent pipe through the wall and connect the coupling as shown to the left. Place the 1/2" mesh metal screen inside the terminal fitting and connect it as shown to the vent pipe on the exterior of the building. Outside of Building Wall Seal any opening around the vent pipe or fittings with mortar or silicone caulk as shown to the left. Complete the rest of the vent pipe installation to the water heater's vent connector fitting on the blower outlet. If necessary support horizontal run as previously mentioned. Care and Cleaning Insert 1/2" Mesh Protective Screen Inside Terminal Elbow Short Piece of Vent Pipe Min. 12" Above Roof Min. 12" Above Anticipated Snow Level. Elbows Max. 24" Above Roof (Without Additional Support) Vent Pipe Through Roof Vertical Vent Termination Location The location of the vent terminal depends on the following minimum clearances and considerations (see illustration): Minimum twelve (12) inches above roof. Minimum twelve (12) inches above anticipated snow level. Maximum twenty-four (24) inches above roof level without additional support for vent. Four (4) feet from any gable, dormer or other roof structure with building interior access (i.e., vent, window, etc.). Ten (10) feet from any forced air inlet to the building. Any fresh or make-up air inlet such as a dryer or furnace area is considered to be a forced air inlet. Troubleshooting Tips Vertical Vent Installation Once the vent terminal location has been determined, make a hole through the roof and interior ceiling to accommodate the vent pipe. Complete the vent pipe installation to the water heater's vent connector fitting on the blower outlet. Support vertical or horizontal runs as previously mentioned. Install adequate flashing where the vent pipe passes through the roof. Determine the vent terminal height and cut vent pipe accordingly. Refer to the above section for proper vent terminal height. Connect vent elbow onto vertical pipe through roof. Connect short piece of vent pipe (approximately 3" long) to elbow, then insert 1/2" mesh metal screen into terminal elbow and join it to the short piece of vent pipe. 15 Customer Service
