WALL GUIDE (WG)
1. The wall guide is used as a lateral guide to resist lateral or side load
only, it is not designed for carrying the weight of a vertical chimney.
It also ensure a minimum clearance of 1” to combustibles for model
DIS and 4” for model DAS. See Figure 27 (wall guide).
2. The proper location to install the wall guide is immediately below a
locking band. The locking band must be able to move without inter-
fering with the guide when thermal expansion occurs. See Figure 28
(wall guide location).
3. The wall guide can be installed with a wall band extension for greater
clearances up to 4-1/4” for model DIS and up to 7-1/4” for DAS. See
Figure 29 (wall guide extension).
4. Special considerations must be taken when installing on exterior wall.
A wall guide must be installed between 6’ and 10’ below the highest
wall support to stabilize the free standing portion of the chimney. Do
not install a expansion length in this area due to bending forces induced
by the freestanding portion. See Figure 30 (special considerations).

WALL SUPPORT (WS)
1. The wall support consists of an Anchor Plate and a prefabricated frame
with mounting brackets and angled struts for bracing.
2. Used to support the chimney in vertical runs, it maintains the chimney
at an adjustable distance between 2-1/2” and 7-1/2” from the wall (see
Figure 26).
3. The maximum weight allowable on the wall support depends if the
support is attached to a metal structure or a wood structure (see table
6 for maximum chimney height).
4. The installation begins by attaching the frame of the wall support to a
rigid metal or wood structure. Adjust the braces to have a minimum
of 45° angle from horizontal. Once the frame of the wall support is
fixed to a rigid structure, the installation is the same as the Anchor
Plate.
