7) Chimney Chase Installation - A vertical 80/125mm vent system can be installed in an unused masonry chimney. This
installation is similar to other vertical installations with the following exceptions (Also see Figure 7.36):
a) The chimney chase elbow kit (P/N 101492-01) is used at the base of the chimney. This kit consists of a support elbow
and a mounting bracket. Slip the elbow over the M10 x 35 screw in the support bracket. Determine the desired
vertical location of the support elbow in the chimney and mark the location of the pin on the back of the support
bracket on the back wall of the chimney. Drill a 7/16"dia x 2-1/2" deep hole at this location to support the back of the
bracket. The front of the elbow mounting bracket is supported by the bottom of the opening into the chimney or by an
installer supplied bracket.
b) Construct a weather-tight flat roof to cover the top of the old chimney. Install the vertical terminal through this roof
using the flat roof flashing.
• Do not attempt to construct a vertical vent system inside a chimney that is used to vent a fireplace or other
appliances.
• Do not attempt to construct a vertical vent system inside a chimney flue adjacent to another flue used by a
fireplace or other appliances.
