Below diagrams are examples of vertical terminations.
Once the vent terminal location has been determined, make a hole through the exterior wall to accommodate
the vent pipe. Vent pipe must only exit exterior wall horizontally.
Place the 1/2" metal mesh screen inside the terminal fitting and connect it as shown to the vent pipe on the
exterior of the building.
Seal any opening around the vent pipe or fittings with mortar or silicone caulk "as shown" above.
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.
