Please contact Bosch Water Heating with any questions.

2.2Locating power vent hood and clearances

The maximum vent length from the water heater to the point of termination is 25 feet with one elbow. If using more than one 90° elbow, subtract 5 feet off the maximum vent length for each additional elbow used. Maximum of three elbows allowed.

The power vent motor must be installed as close as possible to the VH1-4 vent hood.

Clearances

The vent system must terminate so that proper clearances from the center of the vent hood (Fig.

1)are maintained as cited in the National Fuel Gas Code, ANSI Z223.1 and CSA B149.1 in Canada:

“The vent terminal shall also not be installed closer than 3 feet from the inside corner of an L-shaped structure, or less than 1 foot above grade or anticipated snow pack level.”

Also:

“The exit terminals of mechanical vent system shall be located not less than 7 feet above grade when located adjacent to a public walkway. The venting system shall terminate at least 3 feet above any forced air inlet within 10 feet. The venting system shall terminate at least 4 feet below, 4 feet horizontally from or 1 foot above any door, window or gravity air inlet into any building.”

2.3 Power vent hood

1.Attach the mounting template (on page 13) to the interior wall that the vent hood will be penetrating.

2.Ensure that the proposed vent termination clearances are met (Chapter 2.2) before cutting opening through wall. Using a 1/2” drill bit, drill two pilot holes where noted on the template. The drill bit must be long enough to penetrate to the building exterior.

3.Attach the template to the outside of the building aligning the pilot holes on the template with the pilot holes drilled in step 2.

4.Using a reciprocating saw, cut a hole through the building siding, wall board, etc., following the appropriate lines of the template.

5.Apply a bead of exterior-rated caulk to the vent hood flange to seal at the exterior of building.

6.Slide the vent hood through the opening and fasten to exterior wall using screws provided.

7.Install backdraft flapper using the instructions included with flapper.
