HORIZONTAL INSTALLATION (cont.)
Step 4.
Position the horizontal vent termination in the center of the 10 (254mm) square hole, and
attach to the exterior wall with the four wood screws provided. Before attaching the Vent
Termination to the exterior wall, run a bead of non-hardening mastic around its outside
edges, so as to make a seal between it and the wall. The arrow on the vent cap should be
pointing up. Insure that proper clearances to combustible materials are maintained (Figure
7).
NOTE:
(1)
The four wood screws provided should be replaced with appropriate fasteners to stucco,
brick, concrete, or other types of sidings.
(2)
For buildings with vinyl siding, a vinyl siding standoff (Simpson Dura-Vent part 950),
should be installed between the vent cap and the exterior wall (Figure 8). Attach the vinyl
siding standoff to the horizontal vent termination. The vinyl siding standoff prevents
excessive heat from possibly melting the vinyl siding material. Vent terminal shall not be
recessed into a wall or siding.
