INSTALLATION INSTRUCTIONS
Vertical Vent Installation
WARNING: Improper vent
installation can result in death, personal injury,
product damage, and/or poor performance.
NOTICES:
• Only Rheem-approved termination and parts
should be used during installation.
• Maintain the recommended air space clearance
to combustible materials and building insulation.
Cut a hole through the roof and interior ceiling
to accommodate the vent pipes.
Complete the vent pipe installation to the water
heater’s vent connector fittings. Use cleaner-
primer and PVC cement where the vent pipes
join the water heater.
Support vertical and horizontal runs as
described on page 35. Vertical supports are
required every 4 ft. (1.2 m) along a vertical pipe
route, after every transition to vertical, and after
every offset elbow.
NOTICE: Free-standing vent pipe that
penetrates a roof/ceiling requires another means of
support from a second location.
Determine the vent terminal height and install
the vent pipe accordingly. Refer to “Vertical Vent
Terminal Location” on page 44 for clearance
requirements.
Install adequate flashing where the vent pipe
passes through the roof.
