INSTALLATION
SIMPSON DURA-VENT VENTING
The Simpson
The minimum components required for a basic horizontal termination are:
1Horizontal Termination Cap
190o Elbow
1Flue Adaptor
1Wall Thimble
1Length of pipe to suit wall thickness (see chart)
Wall thickness is measured from the back standoffs to the inside mounting surface of termination cap. For siding other than vinyl furring strips may be used, instead of the vinyl siding standoff, to create a level surface to mount the vent terminal. The Terminal must not be recessed into siding. Measure the wall thickness including furring strips.
If a Vinyl Siding Standoff is required (it must be used with vinyl siding), measure to outside surface of wall without siding and add 2 inches.
