Snorkel Terminations

For installations requiring a vertical rise on the exterior of the building, 14-inch and 36-inch tall snorkel terminations are available. When us- ing a snorkel, the stove can be vented directly out the back. There is a vent starter collar fastened to the stove (to vent straight out the back), remove the four screws securing the collar, rotate the collar 180 degrees and refasten using the same four screws. Make sure the gasket between the collar and the stove is properly positioned before refastening the collar. After rotating the collar, it will be positioned horizontally. When this pipe passes through a wall, a wall thimble - Simpson part number 942or Security™ part number SV4RSM is required. The hole in the wall for the wall thimble should be 9-1/4” wide by 10-1/4” high. To vent out the rear wall, add up to a 12” section of pipe and then the snorkel. When the stove is located in a corner of the room, to vent horizontally first add a 45 degree elbow, then up to a 12” section of pipe and lastly the snorkel. Installations using a snorkel have no restrictor installed in the pipe (see Pages 13 and 14 for restrictor positioning). Follow the same installation procedures as used for standard horizontal terminations. If the snorkel termination must be installed below grade, (i. e. basement application), proper drainage must be provided to prevent water from entering the snorkel. Do not attempt to enclose the snorkel within the wall, or any other type of enclosure. On vinyl siding, furring strips may be used to ensure that the snorkel is not recessed into the siding.
