Vertical Installation:
Vertical venting must be supported every 5 feet of vertical run and every 3 feet of horizontal run of vent pipe length.
Stress levels in the pipe and fittings can be significantly increased by improper installation. If rigid pipe clamps are
used to hold the pipe in place, or if the pipe cannot move freely through a wall penetration, the pipe may be directly
stressed, or high thermal stresses may be formed when the pipe heats up and expands. Install accordingly to minimize
such stresses.
Failure to properly support the vent piping with hangers and clamps may result in damage to the water heater
or venting system.
