SIMPSON DURA-VENT VENTING
Horizontal or Vertical Terminations
The Simpson Dura-Vent Direct Vent System offers a complete line of component parts for installation of both horizontal and vertical installations. Many 
items are offered in decorative black, as well as galvanized fi nish. We recommend using the galvanized fi nish for installation with the P48-2.
The minimum components required for a basic 
horizontal termination are:
1 Horizontal
Termination
Cap
1 45
o
Elbow
1 Flue
Adaptor
1 Wall
Thimble
 1 Length 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.
