B.  INSTALLATION  OF THE VENT HOOD TERMINAL
1. Inspect Direct Vent Conversion Kit Carton for 
damage. DO NOT install if any damage is evident.
2.  Direct Vent Conversion Kit Carton includes (see 
Figures 15, 16, 17):
•  Direct Vent Hood Assembly (consists of Vent 
Hood Body and Vent Hood Tee) – 1 pc
•  Backing Plate – 1 pc
•  Vacuum Relief Valve VRV-4 – 1 pc
•  Hardware Bag (includes high temperature 
sealant, fasteners and inner pipe clamps) – 1 
pc 
•  Appliance (Boiler Flue Outlet) Adapter – 1 pc
•  Appliance Clamp Halves – 2 pcs
•  Cover Sleeve Assemblies – 2 pcs
•  Cover Ring Assemblies – 2 pcs
3. Remove vent system components from carton 
and set aside.
4.  Separate the vent hood tee from the vent hood 
body and set aside for later use. 
5. After determining the location of the venting 
system termination, cut the square hole in the 
wall sized according to “L” dimension in Table 
5, see Figure 14. 
6.  Wood or vinyl siding should be cut, so that vent 
hood base plate mounts directly on the wallboard 
to provide stable support. If siding thickness 
exceeds ½”, use a spacer bar or board behind 
the vent hood mounting (base) plate. See Figure 
15.
a.  Seal the backside of the vent hood base plate 
around the outer pipe of the vent hood with 
a bead of high-temperature silicone sealant 
(provided in Bagged Hardware).
b. Mount the vent hood body from outside, 
through the wall, keeping the outer pipe 
centered in the hole.
