Each figure includes a chart with critical minimum and maximum dimensions which MUST be met. IMPORTANT: If using a venting configuration of only horizontal venting with no vertical run, a 1/4" rise for every 12" of run toward the termination is required. NOTICE: Do not seal termination cap to vent pipe. Cap must be removable for vent inspection and maintenance. WARNING: Never run vent downward as this may cause excessive temperatures which could cause a fire. Operation of improperly installed and maintained venting system could result in serious injury, property damage or loss of life. Horizontal Round Termination Round Termination * If installing this fireplace at altitudes of 4000 feet and above, it is recommended that an additional vertical height of 6" be added to the vent system. Figure 14 - Horizontal Termination Configuration for Square or Round Terminations CORNER INSTALLATION Recommended Applications: • Corner ground floor installation • Ground floor installation where pipe vents horizontally through wall (over 12" horizontal pipe) • Basement installation where one foot clearance from ground to termination is possible SNORKEL TERMINATION INSTALLATION Recommended Applications: • Installations requiring a vertical rise on building exterior • Any installation using snorkel termination to achieve one foot above ground Snorkel terminations are available for installations requiring a vertical rise on the exterior of the building. If installing snorkel termination below grade, you must provide proper drainage to prevent water from entering snorkel termination (see Figure 16). Do not back fill around snorkel termination.

Determine the route your vertical venting will take. If ceiling joists, roof rafters or other framing will obstruct the venting system, consider an offset (see Figure 19) to avoid cutting load bearing members. Note: Pay special attention to these installation instructions for required clearances (air space) to combustibles when passing through ceilings, walls, roofs, enclosures, attic rafters, etc. Do not pack air spaces with insulation. Also note maximum vertical rise of the venting system and any maximum horizontal offset limitations. 2. Set the fireplace in desired location. Drop a plumb line down from the ceiling to the position of the fireplace exit flue. Mark the center point where the vent will penetrate the ceiling. Drill a small locating hole at this point. Drop a plumb line from the inside of the roof to the locating hole in the ceiling. Mark the center point where the vent ...
