Installation
Section 3-2: INSTALLING A ROOF MOUNTED DIRECT VENT
TERMINATION (MVTK-1 / PVTK-1)
This section applies to installations where the direct vent termi-
nation will be roof mounted.
Section 3-2-1: VENTING LAYOUT
Selection of components and details of venting lay out should
adhere to the following guidelines:
 The maximum termination point is 32’ above the replace (NOTE:
if the maximum termination height is used, the ame pattern
may be affected).
 The Vertical termination must be a minimum 2’ higher than where
the termination exits the roong materials, (asphault shingles,
cedar shakes, etc). This distance should be measured from the
high side of the roof slope where the ue ashing intersects the
roong materials. (see Figures 11 to 11c *).
 Termination location must be a minimum 6’ from a mechanical
air inlet.
 Termination location must be a minimum 18” from a parapet wall.
 A maximum of two offsets (each offset is made up of 2-90°
bends) may be made.
 Install a restop at any location where venting passes through
combustible materials and construction.
 Utilize support straps, or support plates, and rings (as required)
to meet acceptable building practices.
 Install all roof ashing and storm collars as shown.
