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.

around the outer pipe of the vent hood with
a bead of high-temperature silicone sealant
(provided in Bagged Hardware).
