The location of the vent terminal depends on the following minimum clearances and considerations (see diagram at left):

Minimum twelve (12) inches (30 cm) above roof..2

Minimum twelve (12) inches (30 cm) above anticipated snow level..

Maximum twenty-four (24) inches (60 cm) above roof level without additional support for vent..

Four (4) feet (1..2 m) from any gable, dormer or other roof structure with building interior access (i..e.., vent, window, etc..)..

Ten (10) feet (3 m) 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..3

Notice: Only Rheem approved termination and parts should be used during installation.

Notice: Follow vent manufacturer’s installation instructions and their recommended clearances to combustibles as required.

Vertical Vent Installation

A fire stop plate should be installed at every penetration of a floor or ceiling if the vent is not running in a fire-rated shaft.. Maintain the recommended air space clearance to combustible materials and building insulation..

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 water heater vent collar outlet.. Support

vertical or horizontal runs as previously mentioned.. If required, use silicone sealant at the point the vent connector joins the water heater..

Install adequate flashing where the vent pipe passes through the roof.. Determine the vent terminal height and install the vent pipe accordingly.. Refer to the diagram above for proper vent terminal height..

The vent roof system must terminate at least

1 foot (30 cm) above the roof line and at least 2 feet (61 cm) higher than any portion of the
