Normal Vent Nipple and Cap
The Emergency Vent Kit requires that one of the openings on the tank be shared between two accessories due to
the addition of the emergency vent which requires its own dedicated connection. The normal vent and level
gauges can be combined to meet this requirement. Roth recommends a field assembled pipe manifold (Fig 1) to
provide mounting capability for both the normal vent and the level gauge.
Level Gauge
To share a tank opening with the vent, a field scalable level gauge is required, the standard Roth level gauge is
a fixed calibration and will not function properly if installed in the required manifold configuration (Fig 1). This
kit therefore includes a field scalable level gauge. Thread level gauge into manifold tee with thread sealant and
hand tighten, no wrenches are required.
The Level-Vent mounting manifold (Fig 1) can be easily field fabricated using the following materials

Installation Steps for Emergency Vent:
1) Inspect the unit for shipping damage. Replace unit if damage is found.
2) Check vent openings for foreign matter such as packaging material. Remove any that is found.
3) Inspect sealing surfaces between cover and body. Remove any dust or debris.
4) Ensure mounting pipe/connection is in the vertical (plumb) position.
5) Verify vent cover is moving freely before and after installation into the system.
6) Do not paint vent unless necessary. If painting, extreme caution must be exercised to make sure that the
paint does not inhibit proper vent operation.
7) Follow appropriate mounting instruction below.
