venting installation
4.1 horizontal installation
16.7.1A
This application occurs when venting through an exterior
wall. Having determined the correct height for the air
terminal location, cut and frame a hole in the exterior wall,
as illustrated, to accommodate the fi restop assembly. Dry
fi t the fi restop assembly before proceeding to ensure the
brackets on the rear surface fi t to the inside surface of the
horizontal framing.
The vent shield must be installed to the full depth of
the combustible wall. The length of the vent shield may
cut shorter for combustible walls that less than 8 1/2”
(216mm) thick.
A. Fold the vent shield up so that it is perpendicular to the
spacer plate.
B. Bend the tabs located on either side of the vent shield so
that they are just shy of 90º to the spacer plate.
C. On both sides of the fi restop, fasten the (W570-0018)
screws through the clearance holes in the bend tabs and
threaded into the holes in the vent shield.
D. Apply a bead of caulking around the outer edge of the
fi restop assembly.
E. Screw the fi restop onto the wall/framing, using 4 screws.
F. Once the vent pipe is installed in its fi nal position, apply
red RTV silicone (W573-0002) (not supplied) between the
pipe and the fi restop.
Bend the tabs for reduced side clearances or move
the shield for reduced top clearances (dependent
on specifi c appliance clearances). Do not fi ll the air
space between the fi restop spacer and the exterior
wall with any type of insulating material (i.e. spray
foam).

• The fi restop assembly must be installed with the vent shield to the top.
• Terminals must not be recessed into a wall or siding more than the depth of the return fl ange of the mounting
plate.
• The vent shield must be fi xed in place by fastening the extended vent shield to the bend tabs using the
supplied fasteners.

Where the venting passes horizontally through a wall, you
MUST
use a Wolf Steel fi restop for all rigid and fl ex vent
systems. The gap between the outside diameter of the vent and the fi restop
MUST
be completely sealed with
high temperature RTV. When using fl ex venting, use fi restop assembly W010-3440 (not supplied).
When using rigid venting, use fi restop assembly 4DHFSN (not supplied).
