II) DETAILED INSTRUCTIONS
1. Drill or cut an opening through the exterior wall and fasten
the vent terminal as shown in Figure 3.
2. Push the vent terminal from the outside through the wall
and fasten the outer shield with the 4 screws provided.
3. Seal around the perimeter of the outer shield with caulking
material which has a temperature rating of at least 167°F .
Note: A silicone type of caulking is recommended.
4. From inside the home, place the second shield around the
tube of the vent terminal and fasten it with the 4 screws
provided. Tighten the gear clamp securely. This completes
the installation of the vent terminal.
5. Maintain clearances to combustible material (2” x 4” or
2” x 6” framing) as per Figure 3. Note: If the flex duct is
to be located between joists, the spacers provided must
be used to maintain clearances to combustible material.
6. Inside the home, attach the smaller end of the flex duct to
the vent terminal. Use the 3 in. band clamp with the gasket
attached (inside the clamp). The edges of the band clamp
must engage both beads (the one on the vent terminal
and on the flex duct) so that the gasket straddles the joint.
7. Run the flex duct to the water heater. All bends should
be as generous as possible. Avoid sharp bends. Do not
kink the duct.
8. Support longer horizontal runs. Maximum spacing must
not exceed 3 ft. (see Figure 2).
If the flex duct is run between ceiling joists, the spacers as
provided must be used. See the details illustrated in Figure 4.
